Furuno FR-2135S Changing AC Power Specification of Display Unit, When the de-icer is installed

26.Check for miswiring, loose screws. Grease the fixing bolts for the cover, gas- ket, and tap holes in the scanner chassis. Attach the cover.

When the de-icer is installed

1)Before beginning any work on the scanner unit, turn off the breaker for the de- icer line at the main switchboard to remove the power (100 VAC, 1ø) to the de- icer. (Turning off the power to the display unit has no effect.)

2)The neck of the scanner unit becomes VERY HOT when the de-icer is working. (The de-icer turns on when ambient temperature is below 0°C.)
