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.
