- If five beeps sound and “Ack Rcvd” is displayed, the status was received and 

acknowledged by the system.

P25 packet data transmission capability is available with Viking VP600 radios. A P25 
Packet Data option button (if programmed) or menu parameter can be used to toggle the 
data mode on and off. See Section 9, "Data Features" for details.

The P25 Packet Data mode allows a subscriber unit to act as a packet data modem for a 
remote application connected to the subscriber unit through an RS-232. The standard 
programming cable provides the RS-232 port (female DB9 connector) for connecting the 
external data equipment to a Viking Portable 600 radio.

Keypad programming can be enabled only if it has been enabled at the factory and a 
conventional mode option button or menu parameter is programmed for the Keypad 
Programming function. The keypad programming mode is indicated by “Chng Zone” and 

 in the display.
