8.6 SYSTEM/GROUP/CHANNEL SELECTION

In the following description of SYSTEM/GROUP/CHANNEL SELECTION, the term group is used

for both group and channel.

The M7300 SYSTEM/GROUP/CHANNEL knob and the ramp control are programmable for

maximum flexibility. If the SYSTEM/GROUP/CHANNEL knob is assigned to select groups, then the

ramp control is assigned to select systems. If the SYSTEM/GROUP/CHANNEL knob is assigned

to select systems, then the ramp control is assigned to select groups. System, group, and channel

selection is the primary function for these controls.

Either systems or groups can also be selected by entering the select mode and following the selection

mode rules described earlier. The system select or group select modes are entered by pressing SYS or

GRP, respectively, from the standard receive mode. Using the ramp control after entering a

particular selection mode in this manner is the secondary function of these keys.

Several methods, some of which depend on programming, can be used to select a new system. These

procedures are presumed to be starting from the normal receive display.

METHOD 1: If system selection is programmed to the SYSTEM/GROUP/CHANNEL knob, select a

system by turning the SYSTEM/GROUP/CHANNEL knob to the desired system

position. The display registers the new system name on line 1. If the wrap option is OFF

and the knob is moved to a position greater than the number of programmed systems, the

highest programmed system will remain selected.

METHOD 2: If system selection is programmed as the primary function of the ramp control,

select a system by pressing up or down to scroll through the system list. The display

registers the new system name on line 1.

METHOD 3: Press SYS to enter the system select mode and follow the selection mode rules detailed

earlier. Use the ramp control to scroll through the systems.

Several methods, some of which depend on programming, can be used to select a new group or channel.

These procedures assume 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 2. 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.
