7.2.2

W4, W5, W7, and W9 Control Heads

To load an encryption key into a W4, W5, W7, or W9 control-head equipped radio:
1. Turn on the radio and set the volume level.
The position of the D button is not important.
2. Connect the cable from the key-variable loader (KVL) to the microphone connector
on the radio.
3. Load an encryption key into the radio's memory from a KVL using the correct loader
for the radio's encryption type.
Refer to your KVL user's manual for more information on keyloading.

Advanced Secure Operation

NOTE: The Advanced Secure feature is available only on radios that have been equipped by the
factory to support it. The radio must also be equipped with an encryption module.
Advanced Secure incorporates the Multikey feature and a dual-encryption feature into the existing
secure system. Multikey allows a radio to be equipped with multiple encryption keys. A default key is
included and is associated with the current mode. The keys are strapped to a given mode or are
operator-selectable and can be indexed into groups of keys called keysets. The keys are loaded
using a manual keyloader.
In addition, your radio can support up to eight different encryption algorithms simultaneously.
7.3.1

Multikey Operation

The multikey feature can be used in both conventional and trunked applications.
• Conventional Multikey - The encryption keys can be selectively strapped, one per each
channel. In addition, the programmable radio features include operator-selectable keys,
operator-selectable indices, and operator-selectable key erasure. Encryption keys are loaded
into the radio through a KVL.
• Trunked Multikey - If the radio is used for both conventional and trunked applications, the
encryption keys have to be strapped for trunking on a talkgroup, or announcement group, basis.
In addition, a different encryption key can be strapped to other features, such as Private Call,
Dynamic Regrouping, Failsoft, Interconnect, System Wide, or Emergency Talkgroup.
7.4

Erase a Key

This feature allows you to select any one, or all, of the encryption keys to erase.
