NOTE: The above values for settings are examples only. Each transceiver has its own
specific values for each setting.
* DO NOT change the “FM Deviation” value when adjusting UHF models. The
value must be 80 for these models.

5.1.2 TEST CHANNELS AND POWER SELECT
Test channels at the low, middle, and high ends of
the operating band are required to perform the adjust-
ments in this section. These test channels are listed in

* These channels must also be programmed with a digital
Call Guard (DTCS) code of 007N.
Table 5-1, and they must be programmed as regular
channels using the programming software described in
Section 3. There are no fixed test channels or test
modes available with this transceiver.
In addition, the High/Low power switch should
be programmed. However, if the PC board is removed
from the chassis (see Section 5.2), this switch is not
available. Therefore, some frequencies need to have
one channel programmed for low power and another
for high power so that power can be selected from the
computer by changing the channel.
5.1.3 COMPUTER-AIDED TUNING
To make most adjustments described in the fol-
lowing information, the computer setup used for pro-
gramming (see Section 3) and special Adjust software
are required. The Adjust software is included on the
disk with the programming software in a separate sub-
directory called ADJ. To set up the transceiver for use
with this equipment, proceed as follows:
