Group And Channel Selection

Several methods, some of which depend on programming, can be used to se-
lect a new group or channel. These procedures are presumed to be starting
from the normal receive display.
METHOD 1 If group selection is programmed to the SYSTEM/GROUP/
CHANNEL knob, select a group by turning the SYSTEM/
GROUP/CHANNEL knob to the desired group. The display
registers the new group name on line two. If the wrap option
is off and the knob is moved to a position greater than the
number of programmed groups, the highest programmed
group will remain selected.
METHOD 2 If group selection is programmed as the primary function of
the RAMP control
,
isters the new group name on line two.
METHOD 3 Press
selection mode rules detailed earlier. Presses of the RAMP
control will now scroll through different groups.

TRUNKED MODE OPERATION

Digital trunking provides fast communication access at all times, even dur-
ing busy hours. In this mode the operator selects a communications system
and group and the audio communication or working channel (WC) is allo-
cated through digital signaling with the site.

Receiving A Call

1. Turn on the radio by rotating the POWER ON-OFF/VOLUME knob
clockwise (out of detente). A short alert signal (if enabled through pro-
gramming) indicates the radio is ready to use.
2. The display shows the last selected or the power up (depending on pro-
gramming) system and group names. If the radio is unable to obtain a
control channel, line two shows CC SCAN.
3. Adjust the POWER ON-OFF/VOLUME knob to the desired volume
level.
