User questions & answers

Question:	If I want to add an additional remote sensor, what is the model number
Answer:	I purchased this only to find the TGR122N & TGR122NX will not work with it. Therefore it is not a replacement for the BAR208SA. This link will give you the sensors that work with the BAR208HGX. https://www.oregonscientificstore.com/c-206-bar208sx.aspx
Question:	how far away
Answer:	I have 2 different Oregon Sci. stations. This one took a day to reset to daylight savings time and I had to move it to an outside window for it to adjust. The other one changed right at 2am without moving. I don't know if it is the unit I have or the model that has this issue. This station has also had a problem recognizing sensors. This may be the distance issue you are referring to. The manual says 100ft, but I see difficulty at 20ft and a wall between them.
Question:	Does it measure in Celsius
Answer:	Yes, you can choose between C and F for the temperature display.
Question:	can unit be hung on a wall
Answer:	The main unit (the piece with all the information) can't be hung on a wall. Only the outside unit (the smaller piece in the picture) can be hung.

User questions & answers

Question:	Does the clock have different alarm tones
Answer:	Yes you can just pull down off your nose to your chin
Question:	if i leave unit projecting 24/7 does it wear out sooner
Answer:	I would not say waterproof. A little water resistant, but in a steady rain it will absorb water.
Question:	Does this clock have a blue projection light
Answer:	It doesn't have ear holes but thin enough to hear music. I'd say it's definitely dust filtered and breathable at the same time. I use this for my Yellow Ranger cosplay and it's good.
Question:	How can I reverse the projection on the ceiling? I don't see anything in the instructions
Answer:	It’s thin,works great under a motorcycle helmet,so it shouldn’t be a problem

Oregon Scientific RM313PNA_BL Model RM313PNA Projection Atomic Alarm Clock, Indoor Thermometer, HiGlo Electro-luminescent Backlight, Crescendo Alarm with Snooze Function, Blue

These cool little clocks automatically set to the U.S. Atomic Clock and never need adjusting for Daylight Saving Time. The projection feature offers a unique way to read time in the dark by casting soft glowing red numbers on a wall, ceiling, or just about any surface

Key Features

• Automatically sets itself to the U.S. Atomic Clock, never needs adjusting for Daylight Saving Time
• Indoor thermometer
• Projects time onto wall, ceiling, or just about any surface
• Illuminated with HiGlo electro-luminescent backlight
• Crescendo alarm with snooze function
• Icon display of U.S. map with designated time zones

Specifications

• AC adapter included for continuous projection
• Batteries: 2 AA (Not included)
• Dimensions: 4.25" x 2.5" x 4.5"
• Indoor Temperature: Yes
• AC Adapter: No
• Alarm Functions: Yes
• Snooze Function: Yes
• Projection Color: Red

Housed in high-tech blue plastic, this alarm clock is far more sophisticated than its cute appearance may lead one to believe. Whether you check on the time by consulting the clock's LCD screen or by looking at a large red-light projection of the time beamed onto a wall or ceiling, you'll know it's accurate. That's because the clock is equipped with a radio receiver tuned to the U.S. Atomic Clock, and keeps time with split-second accuracy by automatically adjusting, if necessary, to the Atomic Clock's signals six times every 24 hours. From those signals, the 5-1/4-by-4-1/2-inch clock (2-1/2 inches thick) not only shows the precise time, but also displays the date and day, with automatic adjustment for daylight-saving time and leap year, according to the North American time zone for which the clock is set. (The day can be shown in English, Spanish, or French.)

The red-light projection makes it possible to check the time without squinting. If the clock is in battery mode (two AA batteries required but not included), pressing the clock's snooze bar will beam the time onto the ceiling for five seconds--and also backlight the LCD screen. If the clock is plugged into a wall socket with an AC adapter (included), the projection and backlighting will be available either for five seconds with the snooze bar or continuously if a continuous-beam control is set. As a backup, you can set the time, day, and date manually as well as automatically. --Fred Brack

User questions & answers

Question:	I've had this clock for a year now. The projection light will no longer stay permanently on - it used to. What's broken
Answer:	I can only say that we have had about 5 different Oregon Scientific RM 313 PNA self setting projection clocks and after about 6 months the projection light goes out and we have to re order another one because we don't know what to do about it.we also need an answer
Question:	once it rings, I can turn alarm off pushing alarm icon; but I can't deactivate the alarm pushing same icon. clock alarms at 5 a.m. every day. help
Answer:	Pushing the alarm button once turns it off for the day. Pushing it twice turns the alarm off, period. (Look at the display & you can see the alarm is not set.) To set the alarm again, push the button. Look at the display, & the alarm will show as set.
Question:	Can the projection light be repaired
Answer:	I have no idea. I have had it several years and have never had a problem with it. My hunch is that it would cost more to repair it than to buy a new one, but that is just my quess.
Question:	if the power goes off in the middle of the night will the alarm still go off in morning
Answer:	Yes, presuming that the batteries are in and working. When the electrical power goes off, the ceiling projection light goes off but the clock, face illumination and alarm still work.

Question:	Is there a way to focus the projection mine is blurry on my ceiling
Answer:	I’ve had no problem with the focus on my ceiling... and I don’t think it is adjustable. Maybe there is a protective film covering the projector. You may have to return it.
Question:	Does it work in the mountains
Answer:	Assuming the clock can receive the signal from the US atomic clock, it should work in the mountains. The clocks have a time-zone setting on them.
Question:	Does this clock automatically change between standard time and daylight savings time? if not, how does the owner adjust it
Answer:	it is supposed to, but we would have to take it to another part of the house to pick up the radio signal. We just change the time zone back and forth from mountain time to pacific time. Much easier than resetting the clock every six months!

User questions & answers

Question:	can the projection light be turned off when not needed
Answer:	Measuring the area where the temperature sensitive paper is located, the thickness is 8 mil or 0.008".
Question:	is the projection feature an option do you have to use it
Answer:	We do have a Thermolabel TL8-100 but do not offer it through Amazon because of the special shipping/special packaging required to safely ship low temperature indicators in warm weather.
Question:	i want the projected display to stay on the whole night while plugged - both light go off after few seconds - it defies the purpose
Answer:	It marks when you get to the temperature that the particular stick is designed for. If your not getting a mark then your material has not reached the appropriate temperature.
Question:	how big is the display on the ceiling
Answer:	I had fired my .308 WIN brass five times and noticed that my groups had opened widely. Being a novice reloader at the time, I did an internet search and learned about work-hardened brass and how it can be corrected by annealing. I created a device that will rotate the brass while being heated with a propane torch for uniform heating. I put a "cam" on the rotating base that trips a switch that lights a light. I touch the Markal to heated brass to see if it melts. It's been a few years since I've done it but I think it took seven revolutions (approximately 10 seconds) to heat the brass to melt the Markal stick(~750°) which is the recommended temp that I found in my internet searches for annealing brass. You will want to start with scrap brass to get your time duration as the Markal leaves some residue on the brass that is difficult to remove.

User questions & answers

Question:	Does it show seconds on the screen and does it project seconds
Answer:	It does show seconds on the screen, but does not project them.
Question:	how do you flip so the date is showing correctly on the ceiling
Answer:	We show only the time of day on the ceiling. The time also shows AM or PM. We have elected to not attempt showing the date.
Question:	How big is it
Answer:	Hi John I can guestimate ...it's about 4" in height and about 5" width and2" deep. I recommend it
Question:	Is the projection angle adjustable? In other words, if the clock is on the nightstand, can I set it to project the time above the middle of the bed
Answer:	I'm able to angle it. But, when you get it too far away from you (like across the room), it distorts the numbers. I like it on my night stand because it gives a nice, crisp reading. And, I don't have to move my head much to see it.

Answer:	There is a sending unit that you put outside that sends the reading to the clock. We have our sending unit under our deck out of the direct sun for a more accurate reading
Question:	Why clock did not change for dst last night
Answer:	Mine did not change last night. I removed the batteries from both and installed new batteries. It is 9:29 am DST; clock still shows 10:29 am EST. I guess I will wait a few more hours. I have another atomic clock and it changed within 2 hours.

User questions & answers

Question:	There are 3 different answers for the siaze of the numberals and letters on the face. Does anybody know the right size? Thank you
Answer:	I get 1 1/8 inch in height and approx. 3/4 inch wide for the numbers in the time. The only letters on the face are am/pm and time zone which are very small at 1/4 inch, and the day of the week which is 3/4 inches wide and 1/2 in height
Question:	Can anyone tell me the actual depth? Thank you
Answer:	The numbers are: Wide 24,5 - Height 16,0 & Depth 4,5 cms
Question:	is it backlit
Answer:	Yes. The backlighting can be turned on and off. However, when it is on it is not bright enough to read the numbers clearly during the day. The backlighting is sufficient for reading the numbers when it is dark. You can also push the snooze button on top to temporarily increase the intensity of the backlighting and then it can be read in the daylight. Note that the photograph that is shown on Amazon appears to be the increased intensity backlighting provided by pressing the snooze button.
Question:	How accurate is the clock time ? Some clocks take their time from the electrical system, others have their own timing oscillator
Answer:	The clock is battery powered, so it won't be using the oscillation frequency of your AC power to keep time. As with many of Marathon's clocks, it resets itself each night using the WWVB radio signal broadcast by NIST from the site of their atomic clock in Colorado. It does its own internal timekeeping for the following 24-ish hours, until it resets again the next night (they do it at night because the atmospheric conditions are better then for signal reception). As long as it is placed somewhere that can receive the signal reliably, it'll be quite accurate (usually within a second of the correct time); the nightly reset corrects for any drift present in the clock's internal circuitry. I have one of Marathon's larger wall clocks that operates on the same principal, and halfway through its 24 hour cycle, it's within a fraction of a second of an extremely accurate time source (iOS apps called "Atomic Clock (Gorgy Timing)" and "Emerald Time", which actively get current NTP readings that are accurate to within 100 milliseconds).

Product features

Large Easy-to-Read Display

The large wide-angle easy to read display can select Fahrenheit or Centigrade for the indoor temperature display. Along with the time, day, date and indoor temperature, this clock also displays indoor humidity.

Atomic Self Setting

This Marathon atomic clock is self-adjusting and self-setting, eliminating the need to manually input the time and date. Simply insert the batteries provided with the clock and it will synchronize to the time set out by the atomic clock in Colorado once the signal is received. The clock includes all 8 North American time zones – a worldwide exclusive Marathon clock feature! It can be used anywhere within continental North American including Hawaii.

Auto Backlight

The ambient light sensor ensures the face of the clock is illuminated in the dark and easy to read. this sensor triggers a soft glow to illuminate the dial when placed in low light.
