Installation or repairs made by unqualified persons can result in hazards to you and others.

2 Failure to carefully read and follow all instructions in this manual can result in equipment malfunction, property damage, personal injury and/or death. This service manual is to be used only by a certified service technician. 9. TROUBLESHOOTING Safety Electric charge is still kept in capacitors even when the power supply is shut off. Do not forget to discharge the electric charge in capacitor. Electrolytic Capacitors (HIGH VOLTAGE! - CAUTION!). For other models, please connect discharge resistance (approx. 100 40W) or soldering iron (plug) between +, - terminals of the electrolytic capacitor on the contrary side of the outdoor PCB.
