Viking™ VP600 Portable Radio Operating Manual

• If the Radio ID feature is enabled, the radio will display the (up to twelve-characters) 

Radio ID alias right below the firmware version after the Self Test message during 
startup. Radio ID identifies the personality file used to program the radio, the service 
area for which the radio is programmed, or functional grouping for which the radio is 
programmed. The Radio ID alias display will be included with the Radio Info display 
items in both button/scroll and menu modes. If disabled, the Radio ID menu mode will 
display “N/A”.

• The current power up zone is displayed. If you are on a channel without a unit ID 

(Analog), only the zone is displayed.

• The Individual (Unit/Unique) ID programmed for the power up channel is displayed.

• A tone sounds (if tones are enabled) and the alias of the selected talkgroup is displayed 

continuously.

Programming determines if the radio powers up on the last selected zone or the pre-
programmed home zone. Refer to Section 3.3 for information on the channel that is 
selected. The minimum volume level may be set by programming. This can prevent 
missed messages resulting from inadvertently turning the volume to an inaudible level.

To turn power off, rotate the ON-OFF/Volume control counterclockwise until a click 
occurs. Power may remain on for an instant after turn-off occurs.

A soft power down feature can be programmed to prevent radio power from being turned 
off by accidentally turning the on-off/volume control. Any side button can be programmed 
for this function in addition to its normal function. To turn power off, press this button 
during or after power is turned off in the normal manner (there is no time out).

The enhanced soft power down feature adds a “standby” mode which mutes audio, turns 
off lights, and can block a combination of buttons and switches.

Enhanced Soft Power Down has two modes of operation. The preferred mode can be 
programmed to determine the power down mode completed by the radio.

Normal Mode. If the power/volume knob is turned off nothing happens until the 
programmed side button is pressed.

Standby Mode. When the power/volume knob is turned off,

 the radio displays 

“Standby”,

 audio is muted, and the indicator lights are turned off. The radio remains in 

“Standby” until the power knob is turned back on or the user presses a button that has 
not been disabled.
