Adjusting volume
Depending on the headset/helmet connected to the MP50, the volume may be individually
set to preferred volume by using the volume up/down buttons on the side of the MP50. When
the MP50 is power off-on cycled, it will start up with a default volume setting.
The volume in walkie-talkie mode and headset mode are set individually.
VOX / PTT mode
When a headset is connected to the MP50, it will by default be set to VOX mode. It will
remain in VOX mode until PTT mode is activated by pressing the primary PTT button.
Pressing the secondary PTT button will not take the MP50 to PTT mode, but activate
transmission to the secondary group as defined by the active configuration.
When the MP50 is in PTT mode, VOX mode can be re-enabled by pressing the
Configuration Down and the primary PTT simultaneously. A power off/on will reset to VOX as
well.
