When a call is received...
While on TSQ Condition, when UH-057 receives a code
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 TSQ 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, TSQ stops flashing
and Quiet operation resumes.
Responding to a call automatically removes the channel
from “Quiet" operation. The TSQ and CAL indicators
disappear from the LCD display.
Tone Squelch Scanning
If you are using two or more channels on TSQ Mode, you
can monitor all of these channels for selective calls by using
the TSQ Scanning.
To use this feature:
1. Select any programmed TSQ Channel.
UP
2. Press and hold the
O
switch for about
1
.5 seconds.
TSQ scanning starts and the SCN indicator appears on
the LCD display.
Unlike Normal Scanning, TSQ Scanning checks the
detected carrier for SELCALL information. If no information
is seen, TSQ scanning resumes.
