1 Operating Voltage Selector Switch
As described in Operating Voltage, the DCAB-1 may be set for 110-120V
or 220V-240V AC mains operation. The two-position switch itself shows
either “115V” or “230V” — this is indicative of the center of the range that
is appropriate in each position.

connecting it to AC mains power! Failure to do so can permanently
damage the unit.

2 AC Mains Fuse
A fast-acting 1 ampere fuse is located in a fuse holder on the rear panel.
If you suspect that your fuse has blown, turn off the AC mains switch and
disconnect the AC mains cord. Only then should you remove the fuse
holder by inserting a flat screwdriver in the slot, gently pressing in and
rotating it counterclockwise by approximately 45°. It is spring-loaded, and
will then safely slide out of the holder.
