Feature

Selecting a Key

Using the Menu

1. Refer to the key-variable loader (KVL) manual for equipment connections
and setup.
2. Attach the KVL to the radio. The display shows "KEYLOADING." All other
radio functions, except for power down, backlight, and volume, are
locked out.
3. Refer to the KVL manual for how to load the encryption keys into the
radio.
4. When the key is loaded successfully, you will hear:
- On single-key radios — a short tone.
- On multikey radios — an alternating tone.
This feature allows the radio to be equipped with multiple encryption keys. It
can support up to two different encryption algorithms simultaneously (e.g.,
DVP-XL 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.
1. Press U until the display shows "KEY."
2. Press D, E, or F directly below "KEY." The display shows the last
user selected and stored encryption key, and the available menu
selections.
3. Press V or U to scroll through the list of encryption keys.
NOTE: If you select an erased key, the display shows the key and
"ERASED KEY."
4. Press D, E, or F directly below the desired menu.
- PSET = selects the preset or default encryption key.
