Motorola Solutions Inc. 89FT7036 Manuale Utente

Procedure:
Turn the preprogrammed Secure/Clear switch to the clear 
position.

If the selected channel is preprogrammed for secure-
only operation – when you press the PTT button, an 
invalid mode tone sounds and the display shows 
Secure TX only.

The radio will not transmit until you set the Secure/
Clear switch to the secure position.

Refer to the key-variable loader (KVL) manual for 
equipment connections and setup.

Attach the KVL to your radio. 

The display shows Keyloading, and all other radio 
functions, except for power down, backlight, and volume, 
are locked out.

Select the required keys and press the Menu Select button 
directly below LOAD on the KVL. This loads the encryption 
keys into your radio.

When the key has been loaded successfully, the radio 
sounds a short tone for single-key radios.
OR
When the key has been loaded successfully, the radio 
sounds an alternating tone for multikey radios.

This feature allows the radio to be equipped with as many as 48 
different encryption keys and supports the DES-OFB algorithm.

There are two types:

Conventional Multikey 

 The encryption keys can be tied 

(strapped), on a one-per-channel basis, through Customer 

Programming Software. In addition, you can have operator-

selectable keys, operator-selectable keysets, and operator-

selectable key erasure. If talkgroups are enabled in 

conventional, then the encryption keys are strapped to the 

talkgroups.

Trunked Multikey 

 If you use your radio for both 

conventional and trunked applications, you have to strap your 

encryption keys for trunking on a per-talkgroup or 

announcement-group basis. In addition, you may strap a 

different key to other features, such as dynamic regrouping, 

failsoft, or emergency talkgroup. You can have operator-

selectable key erasure.
