I have a two way motorola sx800r. I bought 5 sets of the radios. I can hear from any radio. But only one radio will transmit to the rest of them. It has to be a setting. I just don't know which one. All the radios are set up with channel 8 code 0. HELP!
We could not immediately find a manual for the SX800, but here is a link to the SX700 which is very similar. http://www.giantintl.com/ContentManage/manuals/Moto/SX700.pdf
With the radio unlocked: You should check your Qt filter to see that it is also programmed the same. It is recommended you use it in the off or minus position for best communications. If this does not solve the problem, try setting all the radios back to the basic Channel 1, Code off, Qt off, position and see if they will work together. Shut off any special features such as vibra call and call alert, as these when not used correctly can also cause issues with inexperienced users.
If this does not solve the problem. Lastly, check your chargers and batteries. Clean battery contacts with a pencil eraser. Trade batteries from the known good unit into one of the others to see if it solves the problem. Read More At : Radio Communications...
