CAUTION

Be careful to check the inverter because high- voltage circuit is incorporated in it.

3)Perform discharging by connecting + , –

polarities by discharging resistance (approx. 100Ω , 40W) or plug of soldering iron to + ,

–terminals of the C14 (printed as “CAU- TION HIGH VOLTAGE”) electrolytic capaci- tor (500µF) of P.C. board.
