Your rst contact
Now that you have your IC-2720H installed in your car or
shack, you are probably excited to get on the air. We would
like to take you through a few basic operation steps to make
your rst On The Air an enjoyable experience.
1. Turning ON the transceiver
Before powering up your IC-2720H, you may want to make
sure the audio volume and squelch level controls are set in
910 oclock positions.
Although you have purchased a brand new transceiver, some
settings may be changed from the factory defaults because
of the QC process. Resetting the CPU is necessary to start
from factory default.
While pushing both bands [M/CALLMW], push [PWR] for
1 sec. to reset the CPU.
2. Selecting the main band
The IC-2720H displays 2 frequencies on left and right bands
simultaneously. However, transmission, some switches and
microphone keys operation are accepted for the main band
only.
Push the desired bands (left or right) [MAINBAND] to se-
lect the main band.
•“Q appears for the main band.
Using the HM-133
You can select the main band from the HM-133.
