8 EDACS OPERATION
8.1 TURNING ON THE RADIO
1. Power ON the radio by rotating the POWER ON-OFF/VOLUME knob clockwise. A short alert
signal (if enabled through programming) indicates the radio is ready to use. Refer to Figure 8-1 for
location of the POWER ON-OFF/VOLUME KNOB.
2. The display shows the last selected system and group or a default system and group (depending on
programming).
3. Adjust the POWER ON-OFF/VOLUME knob to the desired volume level.
4. Select the desired system and group. The display indicates the current system and group names.
5. The radio is now ready to transmit and receive calls.
In the trunked environment, CC SCAN will be displayed if communication with the
system's control channel cannot be established. This may occur if, for example, the
radio is out of range of the trunking site. It may be necessary to move to another
location or select another trunking system to re-establish the control channel link for
trunked mode operations. CC SCAN is displayed on the group line until a control
channel is accessed.
8.2 CONTROLS
The radio features two rotary control knobs and an emergency button mounted on the top of the radio
(Figure 8-1). Push-To-Talk and option buttons are mounted on the side (Figure 8-1). The front mounted
keypad has no buttons on the P7230 Select model, six buttons on the P7250 Scan model, and 15 buttons
