Enhancements
PTT ID (Encode)
When on a channel with the PTT ID
feature, the radio transmits an iden-
tification code (unit ID) to the base
station, indicating which portable is
in operation. This code is sent
whenever the PTT button is
depressed. A sidetone is heard as
the ID is being transmitted; when
the tone ends, start your voice mes-
sage in the standard manner. The
LED glows red during the time that
the ID is sent out.
Call Alert (Decode)
Call Alert works similarly to tone-only pagers. When a Call
Alert (page) is received, a series of 4 beep decode tones
are heard while the LED flashes yellow. The LED continues
flashing yellow and the alert tone continues until the call
alert is acknowledged by the radio. If you transmit by push-
ing the PTT button or change the rotary channel selector
while a Call Alert signal is in progress, the LED stops flash-
ing and the Call Alert tone is disabled.
Voice Selective Call (Decode)
This feature operates like a standard pager providing a one-
time voice message. When a Voice Selective Call is
received by the radio, a one-time 2 beep decode tone is
heard while the LED flashes yellow. The radio unmutes and
the voice message is heard. The LED continues flashing
yellow while the voice message is heard. The Voice Selec-
tive Call feature does not require any action to acknowledge
the message and after the transmission is completed, the
radio returns to normal operation.
Signalling and Channel Scan
Signalling and channel scan are compatible in the P110
radio. However, during scan operation, a Voice Selective
Call on a particular channel could be missed since the radio
may not be checking that channel when the Voice Selective
Call is being sent.
It is recommended that priority scan be selected and the sig-
nalling channel be designated the priority channel to improve
the likelihood that the Voice Selective Call is received.
