Check that MP50 and the PNG Base Station
configuration are set correctly, refer to section 2.14

No transmit in VOX mode

configured VOX Min level, refer to section 2.11
VOX sensitivity.
•
Reduce the VOX Min level, refer to section

The MP50 may also incorrectly detect the
microphone. If the microphone type is known, the
microphone detect can be overridden in the menu,
refer to section 2.19 Menu.

trigger level may be too low. The following actions

section 2.11 VOX sensitivity.
•
Increase the VOX Min level, refer to section
2.11 VOX sensitivity.
