Transmission or receiving problem

Here is a link to the user guide for the T4900. You will find the programming instructions beginning on page 16.

Best regards.

Transmit issues can be related to a bad or poorly charged battery. It takes more energy to transmit than to receive. Try swapping batteries with a known good radio to see if it solves the problem. Clean your battery contacts with a pencil eraser and if needed replace the battery pack.

Best regards.

A few items to check:
Be certain both radios are set to the same:
Frequency
Interference Eliminator Code
Qt filter

For a simple test set the Code, Qt filter, and any other special features to off or zero. This will allow you to find out if the radios will work simply on their frequency. Once you establish this, you can add in the features as you need them.

Are you certain they both have the same privacy codes, not just the same channels?

Try trading the batteries between the units and see if the problem moves to the other radio. If so, replace the battery pack. If the problem persists, you have a defect radio, which needs replaced.

motorola has extra security and will not operate with other radio makes very well. It must be locking out the uniden radios.

Hello snorker,

It could be battery / power issue. Two-way radios draw much more power when transmitting then receiving. If the batteries are weak the radio might work perfectly fine on receive and then cut-out when you depress the Push-To-Talk.

Hi again,

It would seem that you posted twice. Here is the link to your other post with my response.

Cheers.

If you have already checked both radios have the same code and channel both radios must reicive and transmit between each other check if you have any QT in any display this is a third condition to reicive.
