GENERAL OPERATION

The relative volume level can be determined by noting the position of the index on the On-Off/Volume knob. To enable a reference tone for setting the volume, proceed as follows:

•If key press tones are enabled (see page 20), a short tone sounds when front panel keys are pressed.

•If a conventional channel is selected and the Monitor option switch is programmed (see page 26), pressing that switch unsquelches/squelches the receiver and either voice or background noise is heard. If a SMARTNET/SmartZone channel is selected, the receiver cannot be manually unsquelched.

Backlight

The backlight for the display and keypad can be manually turned on by pressing the Backlight option switch if it is available. It can also be dealer programmed to automatically turn on when any key is pressed. It then automatically turns off after a programmed delay so that battery drain is minimized.

Option Switches

The programmable option switches are as follows:

•F1, F2, and F3 on front panel. In addition, with full keypad (15-key) models, the *, and # keys are programmable.

•AUX and FCN on the side panel

If your radio is programmed with both conventional and SMARTNET/SmartZone channels (see page 23), these option switches can be dealer programmed to control a different set of functions for each channel type. For example, the F1 switch could select Hi/Lo Power when a conventional channel is selected and Private Calls when a SMARTNET/SmartZone channel is selected. The available functions in each mode are indicated in the tables on pages 9 and 10. If the programmed functions are not indicated in these tables, consult your
