8. Principles of operation Descriptions of circuit operation ( 1 ) Notes for turning the power “ON / OFF” 1 When the power is turned “ON”, the power lamp (LED1), the heater lamp (LED2) (JT-SB216JSH2-W/H/S- NE only, with the heater switch ON), and blue indicators (LED10, 11) turn on after 1.5 seconds (*1) , and the hand dryer becomes ready for operation.
9. Troubleshooting Work precautions • When servicing, be sure to recreate the malfunction two or three times before starting repairs. • When servicing, always take care to keep proper footing. • Before starting the service, always unplug the power cord from the outlet, or turn off the earth leakage breaker when no power cord plug is provided.
