Standard Conventional Calls
Standard conventional calls are calls to or from other mobile units 
on the selected channel. The proper coded Call Guard signaling (see 
page 27) may need to be transmitted for them to receive your call and 
also for you to receive their calls. Proceed as follows to place and receive 
these calls:
Placing a Standard Conventional Call
1. Turn power on and set the volume as described on page 16. Select the 
channel programmed for the mobile you want to call (see “Channel and

3. Press the PTT switch and the call proceeds as follows:
If the Busy Channel Lockout feature is programmed on the channel, 
the transmitter is automatically disabled if the channel is busy (see 
description on page 27). 
Otherwise, busy and out-of-range conditions are not indicated and 
speaking can begin after monitoring the channel. 
4. Press (and hold) the PTT switch to talk and release it to listen.
Receiving a Standard Conventional Call
1. Select or scan the channel programmed for the call you want to receive 
(refer to pages 20 and 30 for more scanning information).
2. When the call is received, press the PTT switch to talk and release it to 
listen. If scanning, you may have to respond before scanning resumes 
to ensure that the response occurs on the channel of the call.
