6 Volume adjustment when you use an
earphone
r
CAUT/ON
If you use an earphone, you may feel that the
volume is too high even if the volume level is set to
minimum. We recommend that before connecting
the earphone, you set the volume level to the
minimum and perform the following operation to
protect your ears.
1 Press and hold the 4 key and turn the power switch
This operation reduces the volume below the original
minimum volume level.
2 Minimize the volume levels for both bands.
3 Connect your earphone to the External Speaker jack.
4 Set the volume to a comfortable level.
If you perform this operation, the internal speaker
volume is also reduced. If you stop using the
earphone, repeat step 1 to return to the original
7 Switching speaker output when a
speaker-microphone is connected
If you connect a speaker-microphone to the external
speaker jack, you will hear the mixed receive tones
of the VHF and UHF bands from the speaker-
microphone. These tones can be separated to the
transceiver’s internal speaker and the speaker-
microphone.
1 Press the F key then the 6 key.
You will hear the receive audio of the active band
from the speaker-microphone and the receive audio of
the sub-band from the internal speaker.
2 If you want to change the speaker output, press and
hold the F key for longer than one second, then
press the 6 key.
