8 OPENSKY OPERATION
Once an OpenSky system has been selected from the available systems on your P7200 or P5200 series
portable radio, the characteristics described in the following sections will govern operation.

8.1 POWER ON/OFF AND VOLUME CONTROL

8.1.1 Power ON/OFF

Rotate the Power ON/OFF/Volume knob clockwise to power the radio on and counter-clockwise to
power the radio off.
The radio will begin the Startup/Log On/Provision/Self-Test sequence and register on the OpenSky
network. This takes a few seconds. If coverage is available, the radio will display the active talk group
and is ready to use.

8.1.2 Volume Control

Turn the Power ON/OFF/Volume knob clockwise to increase the volume and counter-clockwise to
decrease the volume.

8.2 CONTROLS

The P7200 and P5200 portable radios feature two rotary control knobs and an emergency button located
on the top of the radio (Figure 8-1). The Push-To-Talk (PTT) button and two option buttons are mounted
on the side (Figure 8-1). The front mounted keypad of the P7270 System model has 15 buttons and the
P5250 and P7250 Scan models have six buttons. The P7230 Select model does not have a front mounted
keypad.
