(4) After servicing an insulation check on the external metal connectors and between the blades of the power plug must be performed. Method of checking i

7、nsulation resistance Unplug the power cord and short the both ends of the plug with a jumper wire. Using a 500V insulation resistance tester, check that the insulation resistance value between the plug of the power cord and externally exposed metal parts is 1M or greater. The mechanical power switch

8、 should be turned on if it is available. 3. Caution on replacing the battery Danger of explosion if rechargeable batteries is incorrectly replaced. Replace only with the same or equivalent type recommended by the manufacturer. When disposing of used batteries, please comply with governmental regulat

9、ions or environmental public institutions rules that apply in your country / area. 4. Other Cautions When AC plug is non-polarized and if Main or Primary fuse enters in the Neutral line of AC Mains supply or if there is possibility of Main or Primary Fuse entering in the Neutral line of AC Mains sup
