Connecting Audio Accessories
Plug the audio accessories into the following audio connectors.
The following steps apply to the handsets and headset.
1. Set the
P
OWER
knob to
HI
or
LO
(low power reduces battery drain).
2. Set the
M
ODE
knob to USB. You should hear a background noise in the
handset.
3. Turn the
C
HANNEL
knob to the desired position (
refer to "Tuning the
Antenna" on page 3-5
to set a new frequency).
4. Turn the
V
OLUME
knob to the desired sound level.
5. Transmit by pressing the PTT switch on the handset and speaking into the
microphone.
Note:
The H-250/U handset has a noise cancelling microphone. There is
almost no output when speaking more than 1/2 inch from the microphone.
6. To receive, release PTT.
7. Eliminate background noise by turning the
M
ODE
knob to
SQUELCH
.
This also reduces the receiver current drain.
