CONVENTIONAL FEATURES

Automatic Channel Monitoring

If the selected channel is programmed for Busy Channel Lockout feature (consult your dealer), monitoring is performed automatically. Refer to the description of this feature on page 27 for more information.

Manual Channel Monitoring

The automatic monitoring just described may not be programmed or it may occasionally disable the transmitter even if the channel is not in use. In this case, the channel must be monitored manually as follows:

Rx Indicator - With scanning disabled, note if the green RX indicator on the top panel is on. If it is not, the channel is not being used and you can transmit your call. If it is on, the channel may be busy and you should not place your call (see next paragraph).

Monitor Mode - There may be times when the busy indication is displayed even though no one is using the channel. Monitoring should then be performed by disabling Call Guard squelch using the Normal/ Selective option switch as described on page 28 or the monitor mode described next.

Monitor Mode

The monitor mode temporarily disables squelch control features (such as Call Guard® squelch) so that all messages are heard on the selected channel. It also overrides the Busy Channel Lockout feature (see next section) and temporarily halts scanning.

To monitor the selected transmit channel, select the monitor mode by briefly pressing the Monitor option switch (if available). The icon is displayed and the receiver unsquelches when the monitor mode is enabled. To disable the monitor mode and return to normal operation, press the Monitor switch a second time.

To monitor the selected receive channel instead of the transmit channel, press and hold the Monitor switch until the alert tone sounds
