numbers for selecting a channel and leading zeros are not required.

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.

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

Main
menu is entered, the
message

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
