7 OPENSKY OPERATION
Once an OpenSky system has been selected from the available systems on your P7200 series portable
radio, the characteristics described in the following sections will govern operation.
7.1 POWER ON/OFF AND VOLUME CONTROL
7.1.1 Power ON/OFF
Rotate the Power ON/OFF/Volume Control 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.
7.1.2 Volume Control
Turn the Power ON OFF/Volume Control knob clockwise to increase the volume and counter-clockwise
to decrease the volume.
7.2 CONTROLS
The P7200 portable radio features two rotary control knobs and an emergency button located on the top of
