5.13.9 Call Alert
The Call Alert™ feature allows pages to be sent and received on P25 conventional
channels. The Call Alert Encode and Decode options must be enabled (by programming)
to send or receive an alert. Operation is similar to SMARTNET/SmartZone and P25
Trunking channels.
To answer a page:
