* The rate the P1 and P2 channels are sampled while listening to a non-

priority channel depends whether RF carrier is present or not. If no carrier

is present on P1 or P2, the scan rate is fast. If carrier is detected but

incorrect Channel Guard is present, the rate slows considerably. This

prevents the non-priority signal from being badly distorted by the larger

mute times needed to detect Channel Guard. If Channel Guard is not

programmed for P1 or P2 the scan rate remains fast.

TRANSMIT IN SCAN MODE

Several characteristics in the transmit mode occur if the radio has been placed in

the scan mode of operation.

∗ Radio is in scan mode but there is no carrier activity to stop the scan on any

channel. Removing the microphone from its hookswitch will stop the

scanning activity and the radio will revert to the pre-scan selected channel.

Replacing the microphone will enable the scan mode after a few seconds

delay.

∗ Radio is in scan mode and carrier activity on a channel has caused scan to

stop. Removing the microphone from its hookswitch will keep that channel

selected. When push-to-talk (PTT) is pressed on the microphone, the

transmit channel will be the displayed channel. The channel can be changed

during this time as needed but will be forgotten when scanning resumes.

Placing the microphone back on the hookswitch will cause scan to resume,

after a few seconds delay.

∗

The Channel Guard decode is disabled whenever the microphone is

removed from its hookswitch.

∗ During the scan mode the MONITOR and CHANNEL selection functions

are disabled if scan is not stopped on a channel.

TO PROGRAM SCAN CHANNELS AND SELECT

PRIORITY

The selection of scan channels and priority is front panel programmable using

the SCAN switch in conjunction with the ADD and DELETE switch.

NON-PRIORITY(S)

1. Confirm that radio is turned on (channel number is lit). If not, press the

POWER switch.

2. If SCAN indicator is lit, press and release the SCAN switch to disable scan

function.

Select desired channel using the ADD or DELETE switch.

4. Press and hold SCAN switch, then press the ADD switch once to add the
