6.19 HELP MENU
The options on this menu are as follows:
EMERGENCY TX
CARRIER OFF This provides a short route to switch off the Tx carrier in an emergency. It
is operational even when under Remote M&C and normal access to the carrier
on/off control is disabled (along with most other local control). A single further
submenu provides the `are you sure` type check, pressing 1 at this next menu will
switch off the Tx carrier. Note the key sequence to switch off the carrier is
therefore `911` from the main menu. So the key sequence Main, 9,1,1 will kill
the Tx carrier whatever screen was left active on the display.
NOTE: This is an OFF only selection, to switch the carrier on again you must use
the normal sequence, Change, Tx, Mod, Carrier, On. Although `911` is available
in both local and remote M&C, access to the normal carrier on/off control is only
available under local control. So if a unit is set for remote control, either the
carrier must be switched on by remote M&C, or the unit must be returned to local
control.
