INSTRUCTION MANUAL
USE OF THE POWER SUPPLY
These power supplies have output voltages in different steps. A universal range of output plugs and
a polarity inverter allows these power supplies to be used with most electrical equipment such as
walkman, laptop, radio, CD-player, electrical toys etc. without using batteries.
Read this instruction manual carefully before use!
IMPORTANT ADJUSTMENTS BEFORE USE
1. Check current (mA)
The current (mA) rating of the power supply must be the same or more than that required for the
equipment to be powered (see table 1). The current will be shown on the equipment or in its instruction
manual.
2. Choose the correct connector
The enclosed connectors correspond to the most commonly used. The correct connector should fit
properly using a little pressure. Do not use extreme
force to insert the connector as this could damage the unit to be powered.
3. Set the correct polarity for the equipment to be powered
Look on the equipment or its intruction manual for the polarity and set the coupling socket to the correct
polarity (see drawing)
4. Set voltage for the equipment
Check the voltage (V) required for the equipment and set the selector switch on the base of the power
supply with the arrow pointing at the appropriate voltage. If the voltage is not known start with the
lowest voltage. If the equipment does not work in this position take the next voltage position until the
equipment works.
ATTENTION
These power supplies are for indoor use only. The power supply should be disconnected from the
mains when not in use. Do not plug in the power supply if there are signs of damage to the housing,
power plug/cable or output cable. Never open the power supply.
