Just opened my new MH230R radios and the backlight function is only working on 1 of them.

Check your programming. It sounds like you have chosen a code number in one radio and the other radio has code turned off (zero).

Strange. Could it be any of the radios are from different countries? The channels are not worldwide. For instance, Canadian radios are on different frequencies than USA radios. They look identical.

This is the manual and guide:

It's best to contact Motorola Solutions.

is it water proof? did you dip it in water?... if you did that's why the mic isn't working, the call and mic isnt working

make sure the channel is on the right channel for the walkie talkie

Take the radios back to a very basic setting with all special features turned off. If the radios have a Qt filter check to see it is turned off, and set your Code to zero (off) on both units. Also, check to see your battery is good in both units. Trade the battery with a known good radio to see if the problem moves to the other radio, is a simple test.

buy a new battery

if not :
these are one-way radios. no service, no spareparts. just trough away and buy new
