Safe Operation
To reduce the risk of fire or electric shock, please adhere to these warnings:
- Moisture: Do not expose this appliance to water or moisture.
- Cleaning: Unplug the power supply from the mains power outlet before cleaning. Switching off the power supply will not reduce this risk.
- Ventilation: Place the power supply in an area that will allow air to flow freely around the unit. This will prevent the power supply and mobile radio from overheating. Do not block or obstruct any of the ventilation openings on the unit.

Installation Instructions
- Unplug the power supply from the mains supply outlet.
- Select the correct input voltage (See Input Voltage Selection).
- Connect the power cable’s positive (red) wire to the positive terminal and connect the negative (black) wire to the negative terminal on the back of the power supply.
- Plug the AC power cable into the power socket on the back of the radio.
- Plug the power supply into the main AC wall outlet.
Turning the Power Supply ON / OFF
Turn the power supply ON by pressing the power switch to the ‘ON’ Position. Before you turn the power supply OFF, turn the radio off as described in the user documentation for the radio. Then turn the power supply off by pressing the power switch to the ’OFF’ Position.
Cooling
The SS-30DV power supply is cooled by convection and forced air cooling (normal airflow around the power supply
in combination with a temperature controlled fan to improve cooling at higher levels of use). The fan is temperature activated and the speed is controlled by a sensor. When the temperature rises, the fan speed increases.
Input Voltage Selection
The power supply is set up for 230V AC input as shipped from the factory. For 115V AC applications, set the recessed 115/230 input select switch located on the rear of the power supply into the proper position. Positions are identified on the switch. Use a small screwdriver to slide the switch into position. No adjustment is necessary for either 50 or 60 Hz input.
