User questions & answers

Question:

does it come with instruction mount mannual

Answer:

It depends on how wide your object is. The external dimensions are listed on the web site, but if you look at it, there are indentations around the sides and there is a slight taper from top to bottom. At the middle, it is only about 30/31 inches (Taper). At the sides it is 33/34 inches. It is about 20 inches deep and about 19/20 wide. So if you have a 36 inch level, you can place it in there diagonally. If it is a board 36 x 20 x 1 it might also fit diagonally - but not much else of any size would fit. You get the idea. Rob

Usage Scenarios

1. Channel key does not light----Check the AC power cord. Is it connected properly? Or change AC adapter to test.

2. Cannot receive response---- Please make sure the intercom set to designated channel? If not, be sure to release TALK when you are not speaking into the intercom. Also be sure to press TALK or CALL when the intercom is in MONITOR mode.

3. Cannot talk to another intercom---- Are both intercoms set to the same channel and code? Please make sure they are properly set up and that you’ve waited until the other user has finished talking.

4.Strong and continuous "beep" sound, static noise ----Move intercoms further apart to eliminate audio feedback. Or, change your intercom to another channel or code.

5. Unit doesn't work----Try the units in a different location. If the units work in a different location but not in your home, there may be a problem with your home concrete wall.

6. Cannot communicate----Confirm both units are set to the same channel and code when you want to communicate. Or, change locations by using Power Bank and moving to other locations for better reception and transmission. Or change the channel code.

Note:

1.The intercom system is a real-time communication system which has no memory or storage function. Because of this, you cannot receive any information while you are talking with others. Additionally, you cannot speak to another user if they are speaking at the same time.

2. Please note that you will need to set the same channel and code if you want 2 intercom stations to receive communication. It also means any other intercoms can also communicate if they have same channel code. For example, your neighbors may be able to interfere with your intercom system. We suggest setting another channel or code to avoid interference.

3. A tip for setting your home intercom system

For example, let’s say you have a 4 station intercom system for your home for different rooms. You can set all 4 stations with the same code A(code A, B or C are choices), then you set different channels for all 4 stations. In this case, you can just click a channel number to call others without set code because your codes are all the same. If your system receives interference, you can change it to another code for all of your stations without changing every station's channel making this a very convenient option.

4. We sincerely suggest that you can read User Manual before you use our intercom system.

Question:	Does this system work with homelink in cars
Answer:	Yes it does come with a good instructions and easy to follow.
Question:	Does the system allows for more than one phone number on the same apartment
Answer:	I am using my boxes for pistol 9mm and another for Rifle 30-06, and 12 gage shotgun, all stored in the boxes. All seem to fit, with some adjustment to how the boxes are placed depending on the caliber. It you store the ammo in the boxes then I would say it could store them in limited quantity, but if you loosely store, outside boxes, it in these containers it would store more for shorter periods of time. I found one box where the water seal, rubber ring, was not fitted correctly, and I am not using that box to store ammo. These boxes tapper from top to bottom, so they do not store the boxes easly without leaving some open space.
