Pressing the High/Low Power switch toggles the power setting. The new level is flashed in the display when this switch is pressed as “HI POWER” or “LO POWER”. If power selection is not permitted on the channel, the fixed power level is flashed and no power change occurs. Turning power off or changing channels does not change the power setting selected for a channel.

Conventional Mode Scanning

General

The following information describes scanning features unique to conventional operation. Scan operation common to all modes is described starting on page 20, and scan operation unique to SMARTNET/ SmartZone operation is described starting on page 48.

Selecting a Scan List

When standard scanning with full keypad (15-key) models, one of up to three scan lists can be selected. These lists can be dealer or user programmed as described in the information which follows. With limited keypad (3-key) models, only one scan list is available and it cannot be user programmed. However, nuisance channels can still be temporarily deleted as described on page 23.

Proceed as follows to select a scan list with full keypad models:

1.Press the Scan option switch to enable scanning. The currently selected scan list is momentarily indicated as “Scan x”, where “x” is the list number (1-3).

2.To select one of the other lists, press the number key corresponding to the desired list (1-3) and the selected list is then momentarily displayed as “Scan x”. The selected scan list is stored in memory and does not change until this procedure is repeated.
