10. Troubleshooting

If you experience problems with your PMR-506TX first check
the battery power level as low batteries can cause problems
such as no transmission, weak reception and poor sound quality.
Check the manual and radio display to ensure that a function
(such as VOX) has not been activated by accident.
If this does not solve the problem reset your unit as follows:
1) Switch off the radio.
2) Press and hold the Up button and PTT button together.
3) Switch on the radio.
This will reset the radio to the factory settings and should fix
most problems.
