Viking Portable 600 Radio Operating Manual

To place a Standard Group call:

1 Turn power on and set the volume as described in Section 3.1, Turning Power On and 

Setting Volume. Select the channel programmed for the talkgroup you want to call (see 
Section 3.3, Zone and Channel Select).

2 If the talkgroup is programmed for encryption and is not strapped to Clear or Secure, 

select the desired mode by pressing the Clear/Secure option button or selecting that 
menu parameter. The status cannot be changed if the talkgroup is strapped to Clear or 
Secure. When you change to Secure mode, the display will briefly display the Key 
Alias assigned to this encryption key. Refer to Section 8.3, Clear / Secure Strapping for 
more information.

3 Press the PTT switch and begin talking. An optional talk permit tone may sound to 

indicate when talking can begin. Events that may occur are as follows:

- If in the secure mode and your radio is not programmed with the proper encryption 

key, “Key Fail” is displayed and the call must be made in the clear mode or the proper 
key must be programmed.

The user hears the key fail tone, and will not be allowed to transmit until secure 
mode is disabled or the proper key is loaded to the radio.

- If the busy tone sounds and “Busy” is displayed, the system is busy. Release the PTT 

switch and wait for the call back tone to sound. Then press the PTT switch within 
three seconds.

- If a continuous tone sounds and “Out of Rng” is displayed, you may be out-of-range. 

Drive closer or away from shielding objects and try again.

- If your unit ID is denied, the radio will not affiliate and is denied system access if the 

Unit ID is not programmed on system.

- If an attempt is made to change an analog call from the clear to secure mode and there 

is no available secure channel, “No Secure” is flashed, an error tone sounds, and the 
call is terminated. (SmartNet Only)

- If an attempt is made to change an analog channel from the secure to clear mode, 

“Sec Only” is displayed, an error tone sounds, and the call is terminated.

- If the secure mode is selected by the Secure/Clear option button or menu parameter 

and an attempt is made to transmit on a channel strapped as clear, “Clear Only” is 
displayed and the transmission is denied. Likewise, if the clear mode is selected and 
the channel is strapped as secure, “Sec Only” is displayed and the transmission is 
denied.
