VOX causes the radio
to accidentally enable
transmission
The sensitivity and/or environmental
noise are too high.
Reduce the VOX sensitivity.
The VOX feature
requires speaking in a
loud voice
The sensitivity is too low.
If the environmental noise is not high,
increase the sensitivity or use an
optional microphone.
Logic related faults
(unreadable displayed
symbols, functions )
Incorrect setting caused by a problem
with the power supply.
Recharge the battery pack.
The autonomy of the
battery pack is limited
Commission time is too high.
Try reducing the transmission time
and/or using a low power.
For NiMH battery packs only: memo-
ry effect on the battery pack
Eliminate the memory effect.
