SOURCE: I have 2 Motorola P110 2 Ch Radios. One powers up

There a a few things which could cause this:

1) You have the radio set to an unprogrammed channel.

2) You have a bad, low or defective battery. (Try switching batteries with the other unit and see if the problem goes away.)

3) Your radio needs repair.

4) Your radio has busy-channel-lock-out activated and you are trying to transmit on a frequency which has activity in your area.

The T4500 is a stripped down version of the TalkAbout radios, it does not offer an option to turn the Roger Beep on or off. Sorry.

How to replace the ptt button on a motorola rdu4100


If you are referring to the external button on the radio, the entire front housing assembly must be replaced. If you are speaking of the internal PTT button on the component board you may want to send the radio for repair (approx. $79). Or if you are equipped with a soldering station, you can replace this component yourself by removing the defective part and soldering on the new switch.

Is it possible to fix a non working PTT button on a RDV2020


The PTT button is one of the common failure parts. It is replaceable, but best done by an experienced repair center.

The following things can happen over time:
1) The internal PTT switch can wear out from frequent usage.
2) The user begins to press harder to get the PTT to work, bending the PTT switch further away from the external button the user is pressing.
3) Plastic diaphram, if any present, gets broken in half, and the external PTT switch doesn't work anymore.

Several companies offer flat rate repair on this style unit for around $85.

Best regards.

I can hear what others are saying however i cannot talk to them. I know that i'm on the right channel. RDU4100 Motorola Walkie Talkie


The "others" have an Interference Eliminator Code ( aka PL or code) applied to their frequency. You would need to program the same "code" into your radio.

Here is a link to the user guide: http://www.mytoolstore.com/motorola/rdx_userguide.pdf

You can with the manual determine how to program and/or read-out the radios.
