8.18.3Private Mode

The Private Mode allows the radio to transmit encrypted messages and receive clear or private transmissions. The radio transmits private if the group/channel is programmed for private operation and forced operation is pre-programmed. If auto-select operation is pre-programmed and the radio is in the Private Mode, the radio transmits in the mode of the received call if the hang time is active. If no hang time is active, the radio transmits private.

Cryptographic keys are transferred to the radio using a cryptographic Keyloader. Up to seven (7) different cryptographic keys, numbered 1-7, can be transferred from a Keyloader and stored in the radio. An individual key is automatically selected on a per-group/channel basis according to the radio programming. Groups and channels within the digital system can be programmed for keys 1-7 (private). Up to 8 banks of 7 keys can be stored for private systems. The bank is specified per system.

When operating on a group or channel programmed for Private Mode, all transmissions are private

transmissions and the radio receives clear and private signals. The status icon is displayed when the Private Mode is enabled. If the selected group or channel is programmed for auto-select capability, the

mode may be toggled between private and clear with the key, then following the selection mode rules. Radios programmed for forced private operation do not allow a change of the transmit mode.

8.18.3.1 Displaying the Currently Used Cryptographic Key Number

To Display the Currently Used Cryptographic Key Number for either the system encryption key (for special call such as individual, phone, all, agency or fleet) or the group/channel key (for group or conventional calls), perform the following procedure:

1.Press the button.

2.Use the or button to select "DISP KEY."

8.18.3.2 Key Zero

All cryptographic keys can be zeroed (erased from radio memory) by pressing the button and while still pressing this button, press and hold the OPTION button. Press both buttons for 2 seconds. A series of beeps will begin at the start of the 2 second period and then switch to a solid tone after the keys have been zeroed. The display will indicate KEY ZERO.
