When a call is received...
While on TSO Condition, when
matching your SELCALL ID, it will do the following opera- tion.
1.Automatically responds to the caller by transmitting Acknowledge tones.
2.Informs you that a caller is on the channel by emitting a CALL ALARM (three successive tones in a regular interval for 10 seconds.) and displays the CAL indicator.
3.Flashes the TSO indicator for about 20 seconds allowing you to use the PTT Switch. If you will not be able to respond within the 20 second period, TSO stops flashing and Ouiet operation resumes.
Responding to a call automatically removes the channel from "Ouiet" operation. The TSO and CAL indicators disappear from the LCD display.
Tone Squelch Scanning
If you are using two or more channels on TSO Mode, you can monitor all of these channels for selective calls by using the TSO Scanning.
To use this feature:
1. Select any programmed TSO Channel.
UP
2.Press and hold the 0 switch for about 1.5 seconds. TSO scanning starts and the SCN indicator appears on the LCD display.
Unlike Normal Scanning, TSO Scanning checks the detected carrier for SELCALL information. If no information
is seen, TSO scanning resumes.
