3. To erase a key, hold down the green side button 1
and the orange top button at the same time. When
key erase is complete, the display will show
“ERASED.”
Note: Do not press the orange top button first.
This button may have been programmed for
emergency operation.
If the battery is removed for more than
approximately 30 seconds from a radio that is
turned off, the key may be lost. The key may also
be lost from a radio that is turned on if the battery
is removed for any length of time, or if the battery’s
charge is allowed to drop to too low a level. If the
key is lost, it will have to be reloaded using the
KVL. Battery removal
is not
a guaranteed method
of key erasure.
4. On SECURENET-equipped radios, the two-position
concentric switch selects whether the radio will be
transmitting clear or secure audio, if a mode is
programmed for neither secure- nor clear-only
operation. The two-position concentric switch will
set the transmit operation of the radio before PTT.
The switch cannot change the transmit operation
while the PTT is pressed.
If a mode is programmed for SECURENET-only
operation, and the two-position concentric switch is
in the clear ( ) position, when the PTT switch is
pressed, the display will show “SECURE ONLY,” an
invalid-mode tone will sound, and the radio will not
transmit until the two-position concentric switch is
set to the SECURENET ( ) position.
If a mode is programmed for clear-only operation,
and the two-position concentric switch is in the
SECURENET ( ) position, when the PTT switch is
pressed, the display will show “CLEAR ONLY,” an
invalid-mode tone will sound, and the radio will not
transmit until the two-position concentric switch is
set to the clear ( ) position.
