3.6.8.5 Channel Number Mode
Chan#: Numeric, Alphanum
The channel number may be set as Numeric or Alphanumeric.
When set to Numeric, the channel numbers are 001-255. When in Numeric mode the Goto channel uses
numbers for selecting a channel and leading zeros are not required.
When set to Alphanumeric, the channel label is used in place of the channel number, and may include
letters and symbols. When in Alphanumeric mode the Goto channel function uses numbers and letters for
selecting channels and the entire three-character channel label must be entered.
3.7 Channel

The channel menu allows access to the menus for editing main channels, guard channels, zones and
scan lists. See sections
3.7.1 thru 3.7.4 for details.
3.7.1 Edit Main Channel Menu (Edit Main)
Channel Menu...
Edit Main?
The Edit Main menu allows the operator to change the parameters of the channels on the main transceiver.
To edit guard channels see the Edit Guard menu, section 3.7.2.
The Main receiver continues to operate with the original settings until the Edit Main menu is exited and
normal operating mode is entered. The transmitter is locked out from operation when in the Edit Main
menu.
Select a different channel using the CHAN +/– switch to scroll to the required channel.
Only unlocked channels may be edited from the Edit
Main menu. Channels may be locked from the serial
load program. When channels are locked the message LOCKED! is shown on the lower display and no
channel parameters are displayed.
To edit a locked channel (all channel parameters can be changed), turn the Master Edit mode 'on' from
the maintenance menu (Section
3.10). If master edit mode is on when the Edit Main menu is entered, the
message MASTER EDIT MODE is flashed three times.
To ensure that no channel parameters may be changed, a shorting block may be installed on the agile
edit jumper. In this case, when the Edit
Main menu is entered, the message EDIT DISABLED! is flashed
three times and the Edit Main menu is shown.
When allowed, the channel's parameters that may be changed from the Edit Main menu are listed as
follows.
