15. Remove the insulating tube. Cut off the remaining fuse lead approximately 10-15 mm from the plastic connector housing.

16. Solder the new fuse lead onto one of the existing leads. Replace the insulating tube and solder the remaining fuse lead. Seal the insulating tube with

electrical tape.

minute recharge cycle, during which a “0” will be displayed on the control panel.

37. After the recharge cycle is complete, a “1” will light up continuously on the control panel. NOTE: If error code E1 or E2 is displayed, ensure that the
