Motorola Talkabout T5420. When turned on are on different channels. Hold down Menu button on one nothing happens, on other only a ringing tone. Both cases no change on screen. What is the problem?

The following instructions are for the T289, which is very similar to the T250. It is possible they will work to turn off your beeps.

Alert Tones

The Alert Tones (beeps) on the Talkabout radios are set at a fixed volume

level and cannot be lowered. However, Alert Tones can be disabled. When

Alert Tones are disabled, the radio will receive messages at the volume

setting you've selected, but you will not hear beeps when you press control

buttons.

Disabling Alert Tones:

1. Hold down the Monitor button while you turn radio on.

2. To re-activate Alert Tones, turn the radio off, then on again while holding
the Monitor button down.

Here is a link to the user guide: http://www.motorola.com/mdirect/manuals/T289_User_Manual.pdf

Since you say the frequency is set the same, you possibly have the code set differently. Check your interference eliminator code. It must be set the same on all radios. For basic operation turn the code off (zero).

Best regards.

On most TalkAbout radios you hold in the plus (+) button while turning on the radio.

Hold in the + button while turning the radio on will turn on/off the roger beep. Here is a link to the user's guide: http://www.giantintl.com/ContentManage/manuals/Moto/T5320_T5410_T5420_User_Manual_E.pdf

You can find the manual here http://www.giantintl.com/motorolafrsold.htm by using the menu to select your radio model.

You most likely will need to program your radios to match one another. Pay special attention to the interference eliminator code and the the Qt filter (if any). Both radios must match perfectly to communicate.

google this :manual for Motorola talkabout t5420.

I have not looked up the T5420 user guide, however, on most Motorola TalkAbouts you hold in the minus (-) button while turning the radio on. Post back if this doesn't work, and we'll find the manual for you.
