Viking™ VP600 Portable Radio Operating Manual
SmartNet / SmartZone / P25 Trunked Features
If an emergency call is received by the radio on the selected channel, the emergency alarm 
ACK tone will sound (five consecutive tones), and the “Emerg Rcvd” message is 
displayed, followed by the unit ID of the emergency radio. If any other emergency calls 
are made after this initial one using a different radio, the tone will not sound, but the unit 
ID will be updated to reflect the most recent emergency call. To exit this state, press the 
button programmed for “Emergency Clear”. The radio returns to its normal display, and 
the “Emerg Rcvd” message no longer displays.
6.8.3 Emergency Calls
An emergency call urgently requests access to a voice channel (an emergency tone usually 
does not sound at the console unless the call is combined with an Emergency Alarm). An 
emergency call is placed by pressing the PTT switch after pressing the Emergency option 
button or selecting the Emergency menu parameter. If the Emergency Hot Mic feature is 
enabled, the emergency call is automatically transmitted without having to press the PTT 
switch (see following description).
6.8.3.1
Emergency Hot Mic
If Emergency Hot Mic has been enabled for emergency calls, automatic transmitting 
occurs with microphone audio unmuted without having to manually press the PTT switch. 
The automatic transmit period is programmed for 0 to 120 seconds in one-second 
intervals. If this feature or emergency calls are not enabled by programming, automatic 
transmitting does not occur. This feature is initiated only on the first press of the 
Emergency button. Subsequent presses do not trigger automatic transmissions. To reset 
this function, cycle power or press and hold the Emergency button.
6.8.3.2
Placing an Emergency Call
If required, select a channel of a system on which Emergency Calls are enabled and 
press the Emergency option button or select that menu parameter. The Emergency 
Alarm is then sent as described in Section 5.9.1, Emergency Alarms if applicable.
Emergency Alarm entry is displayed upon the pressing of the Emergency button. 
Console Ack is displayed when an ack is received back from the console for an 
Emergency Alarm, indicating that the dispatcher acknowledges the emergency. 
Emergency Exit is displayed when the user presses and holds the emergency button. 
Below are the tones for Emergency.
