Viking Portable 600 Radio Operating Manual

The telephone call feature allows telephone calls to be placed and received over the public 
telephone system using your radio. For P25 Trunked/Conventional/Smartnet/SmartZone/
Multi-Net Telephone Calls, the Land Mobile Radio System must be connected to a 
telephone system. Users should check with the System Administrator to see if Telephone 
Calls are allowed on their system. Telephone calls are programmed to operate in one of 
the following modes:

• Disabled

• Answer-only capability

• List only - Telephone numbers can be selected from a pre programmed list only (direct 

entry using the keypad is not allowed).

• Unlimited - Telephone numbers can be selected from a list and also dialed directly 

using the keypad.

DTMF keypad models can place telephone calls by recalling the telephone number from a 
pre programmed list as just described. However, only DTMF keypad models can directly 
dial telephone numbers using the keypad. The keypad remains active during a call for 
overdialing DTMF digits.
