Encryption: Multikey Feature 7-3
7.2 Multikey Feature
This feature allows the radio to be equipped with multiple encryption keys. It can support two or more
encryption algorithms simultaneously (e.g., AES and DES-XL).
• Conventional Multikey – The encryption keys can be tied (strapped), on a one-per-channel
basis. In addition, the radio can have operator-selectable keys, operator-selectable indices, and
operator-selectable key erasure. If talkgroups are enabled in conventional, then the encryption
keys are strapped to the talkgroups.
• Trunked Multikey – If the radio is used for both conventional and trunked applications, strap
the encryption keys for trunking on a per- talkgroup or announcement group basis. In addition,
a different key can be strapped to other features; for example, dynamic regrouping, failsoft, or
emergency talkgroup. The radio can have operator-selectable key erasure.
7.3 Select an Encryption Key
You can select an encryption key using either the menu or the keypad.
7.3.1 Use the Menu
To select an encryption key using the menu:
1. Press
> until the display shows “Key”.
2. Press
{, |, or } directly below “Key”. The display shows the last user-selected and
-stored encryption key.
3. Press
^ or v to scroll through the list of encryption keys.
NOTE: If a deleted key is selected, “ERASED KEY” will be displayed.
4. Press
{, |, or } directly below the desired menu.
• SEL = saves the newly selected key and returns to the home display.
5. Press

Multi-function knob to exit this menu.
• If the selected key is erased, the display shows “KEY FAIL” and the radio sounds a
momentary keyfail tone.
• If the selected key is not allowed, the display shows “ILLEGAL KEY” and the radio sounds a
momentary illegal key tone.
