CONVENTIONAL FEATURES

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 Zone Selection” on page 18).

2.Monitor the channel automatically or manually as described on page 25.

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.
