5.1 Power Supply
Supply voltage is applied to the output connector pins 8 and 15. The voltage source should supply
a stable noise-free voltage. Do not exceed the maximum voltage.
Pin 8: –3 V to –8 V
Pin 15: +3 V to +8 V
Warning: Do not mismatch the polarity of the power supply. A false connection may damage the unit.
