6-2. Line Voltage Conversion
The primary winding of the power transformer is tapped to permit operation from 110 or 220Vac ±10%, 50/60Hz
line voltage. Conversion from one line voltage to another is done by change AC input selector switch.
The rear panel identifies the line voltage to which the unit was factory set. To convert to a different line voltage,
perform the following procedure:
1) Make sure the power cord is unplugged.
2) Change the AC select switch to the desired line voltage position.
3) A change in line voltage may also require a corresponding change of fuse value. Install the correct
fuse as listed on rear panel.
lf the output voltage is unstableness, please check the AC line that it may be less than 207V/105V.
6-3. Cleaning
To clean the power supply, use a soft cloth dampened in a solution of mild detergent and water. Do not spray
cleaner directly onto the instrument, since it may leak into the cabinet and cause damage.
Do not use chemicals containing benzene, benzene, toluene, xylene, acetone, or similar solvents.
Do not use abrasive cleaners on any portion of the power supply.
Should the problems can not be solved, please contact local distributor or the manufacturer.
