OFF position (Fig. 1c, pg. 3). Remove front faceplate to access fuses.
Replace with fuses rated @ 3.5A/250VA (R248220 and R248300220).
Replace with fuses rated @ 5A/32VA (R248600220).
b. Tripped PTC (R248CB220, R248300CB220, and R248600220) - to reset PTC, set power switch on the
back of the unit to the OFF position. After approximately 30 secs. set power switch to the ON (RESET)
position
(Fig. 1c, pg. 3).
