Receiving a Voice Selective Call
1 When a call is received, the green LED blinks,
and a one-time, two-beep alert tone is emitted;
on the display, the call-received status
annunciator (F) blinks. A voice message will
follow.
2 The display shows the
incoming caller's ID
number momentarily.
3 Return the radio back to voice selective call
operation by pressing the monitor button, or if
so programmed, the radio can automatically
reset to voice selective call.
4 The radio returns to the
home display.

caller's ID number is stored in your radio as
the "last ID number received".
• Two automatic-reset features are available
for voice selective-call. These features
reset the radio to voice selective call when
the automatic reset timer expires.
1. Automatic Reset Without Carrier Override
The automatic-reset timer starts after the last
voice message is completed, or after the radio
is de-keyed (you released the PTT switch).
2. Automatic Reset With Carrier Override
When a carrier is detected, the automatic reset
timer stops; when the carrier is lost, the
automatic-reset timer starts over.
• Voice selective call automatic reset is
cancelled when the monitor button is
pressed, or when the mode is changed.
The automatic-reset timer is started over if
it was running when either a voice
selective call was again decoded or a
successful transmission was completed.
Making a Voice Selective Call
There are four phases in making a Voice Selective
call, namely
• initiating a Voice Selective call,
• entering the desired radio ID number,
• sending the radio ID number, and
• having the conversation.
