Adjustment Condition & Tuning
Check that the deviation in the bandwidth is as the
values below.
WIDE ± 3.60 ~ 4.50 kHz
NARROW ± 1.80 ~ 2.30 kHz
Check that the modulation in the bandwidthtion is as
the value below
WIDE/NARROW
Connect a linear detector via the attenuator
to the antenna terminal, then reset so that
each signaling type can be output.
DTCS CODE 007
CTCSS 88.5 Hz

DTMF # (Auto Dial Setting)
Set the linear detector to the following.
HPF OFF
LPF 20 kHz
De-emphasis OFF

Transmit while making sure no input is
applied to the mic (or mic terminal), and
check that each version in it's bandwidth
is as the values below, respectively.
