OPERATING INSTRUCTIONS
USE OF THE POWER SUPPLY
The power supply have output voltages in 6 steps (3.0V; 4.5V; 6.0V;7.5V;9.0V;12.0V). A universal
range of output plugs and a polarity inverter allows to use the power supply for a lot of electrical
equipment like walkman, 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 no 1). The current will be shown on the equipment or in it´s
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 set 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 (3) to the
correct polarity (see drawing no. 4)
4. Set voltage for the equipment
Check the voltage (V) required for the equipment and set the selector switch (2) 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 (3.0 V). If the equipment do not work in this position take the next voltage position
until the equipment works.
ATTENTION
The power supply 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 in case of damaged cabinet or power plug. Never open the power supply.
