User questions & answers

Question:	Does the scroll ring on this mouse have clicks that you can feel while scrolling - when scrolling through a set of images to be able to know that you
Answer:	Only compatible with standard definition receivers like the D12, R16, H20 thru H24. Also note that if you have an H25 HD receiver or Genie, these receivers are only SWM compatible (you will need a SlimLine SWM dish) and will not work with a standalone 18" round dish.
Question:	Can the Expert side scroll? I use spreadsheets that are really wide and have a lot of columns and need that feature
Answer:	No, the pipe is too small. It requires 2" outer diameter mast. You can use a pipe adapter instead of buying a new tripod if it won't hold a 2" OD pole.
Question:	Does it work on Linux
Answer:	The RG6 coaxial cable is sold separately and does not come with it. I recommend Solid Copper Core conductor RG6 cable with compression connectors on each end.
Question:	does left click result in double click after use
Answer:	Tell you truth, I could never get the damn thing to work at all with my HR54. I finally just gave up and bought a Dish Playmaker for my RV.

User questions & answers

Question:	Are the dimensions given in the Technical Details on this sales page (4.25 x 2.5 x 1.25 inches) correct
Answer:	Mine measures 4.0x2.375x1.25.
Question:	Does this use the k75228ww receiver? i have a pro fit wireless keyboard (w/o receiver), and so i'd like to get a compatible mouse and connect both
Answer:	Hi, sorry that the K75228WW receiver won't be compatible with Pro Fit Wireless Keyboard. Thank you for your question!
Question:	Does the nano receiver need to remain plugged into the computer's USB in order to use the mouse
Answer:	Hi, this wireless mouse is connecting through the USB receiver so please keep the USB receiver plugged into your device while using. Thank you for your question.
Question:	Can you turn off both the mouse wheel light and the logo light
Answer:	As far as I've found, you can use the annoying software to turn off the lights. I haven't tried this yet, but maybe you could take it apart and remove/destroy the LEDs, or cover the logo with hockey tape.
Question:	Is it the 2013 edition
Answer:	As of my purchase in 2018, this is now called the DeathAdder Expert although it looks and feels exactly like the 2013 edition I used to have -- in case anyone is looking at these questions now and wondering.
Question:	For left handlers
Answer:	Yes, I own and use 2 - one on my desktop where I play WOW and one on my laptop where it functions as a regular mouse. If you search on Amazon for 'Razer Deathadder', you will find various titles: Razer Deathadder Black 3500 High Precision 3.5G Infrared Gaming Mouse, Razer DeathAdder - Gaming Mouse Left Hand Edition and more. It's all the same mouse. The title of the page varies dependent on which selection it decided you wanted and how you worded your search. Don't worry about it. The important things is that right below where it says "In Stock", there will be a line that says 'style'. It's here where you can choose 'left-hand edition'. If you do that and there are no screw ups, you'll get a left handed version of this mouse. Note, this will be the previous model. When I checked inorder to answer you, I saw there is a 2013 edition. I chose left hand edition, I went to the left hand previous model. I don't know if there is a left hand version of the 2013 version. We would have to call Razer. The left hand version is simplistic as I stated in my review if compared to right handed gaming mice. But it's a good mouse and it's left handed. Please contact me again if I can help further.
Question:	Do all the buttons work in OS X? (Primarily the side buttons) I don't care about drivers, just as long as the buttons function
Answer:	The primary buttons work as expected (top left, right, and center click), and the scroll wheel works as expected. In addition, there are two buttons on the right side arranged front to rear, which can be programmed for a variety of functions using System Preferences in Mac OS X. I do not use the side buttons, but I discovered that I could use them for things like Mission Control, Application Windows, Show Desktop, or Show Dashboard.

User questions & answers

Question:	How do you scroll with the Orbit Wireless Mobile Trackball
Answer:	There is a touch pad on both sides of the trackball that you swipe up or down to scroll. The positioning of the touch pads make it so I can use this mouse with either hand. The only caution I have is that you do not touch the top of the mouse while you are operating the trackball. I have small hands, so when using the trackball with my right hand, I usually put my thumb on the left button, my index finger on the track ball, the middle finger above the touch pads on the mouse where it can easily be put to use on scroll pad, and my ring finger on the right button. I invert this position when I am using my left hand.
Question:	Would you please tell me the length,width and depth. Also from the size from the wrist area to the ball. Thank you
Answer:	Depth = 1 1/2", Legnth approx 4", width = 3 1/2" down to 3 1/4", Wrist area to ball is approx 3". It works well, though is only prefers batteries with a stronger strength to them.
Question:	Has anyone figured out how to disable the scroll ring? I don't see how to do it in TrackBallWorks. maybe a device modification
Answer:	The scroll ring sensor can be disconnected with a few minutes work. Switch off the trackball device and push out the red trackball. I removed the batteries. With a tiny, thin screwdriver pry up the sensor ring (the flat black ring around the red trackball when it's installed). The sensor ring is one fairly sturdy piece. Take your time, attacking at several points, using more than one screwdriver, and you will get the sensor ring out. I did it without scratching the trackball device. At the front of the sensor ring is a ribbon cable. Pull the ribbon cable out of the sensor ring cable connector, fold the cable up and stick it down into the trackball body, then reassemble. It looks and works great. Wear safety glasses! You assume all liabilty for your actions; this is an information-only story how I did it. I like the track ball a lot now that it no longer causes random stuff to happen at random times. If you have mini security allen wrenches for disassembly, you can take the bottom off and likely reach the other end of the cable.
Question:	Is there a way to get scroll click or middle click results with this mouse
Answer:	Yes, definitely. I configured mine to perform middle-click whenever I press both the left and right buttons simultaneously. I had to download Kensington' Trackball Works driver software to get this functionality in Windows 8.1.
