3.5.1 AC Voltage Selection
As shipped, the Aural Exciter Type III is set for 120 VAC operation, but you
can change your unit to match any standard AC line voltage simply by
reprogramming the voltage programming card in the fuse holder in the
following way:
1. Remove the power cord from the chassis receptacle.
2. Slide the clear plastic cover to the left to uncover the fuse
compartment.
3. Remove the fuse by prying out the "fuse pull" lever.
4. Pull out the small printed circuit programming tag.
The tag has four voltages printed on it which are labelled 100/220 on one
side and 120/240 on the other side, as shown in Fig. 3-3. Orient the tag so
the required voltage is readable on the top left side of the tag, and reinsert
the tag in the fuse holder. You should now be able to read your correct line
voltage through the window of the fuse holder.
3.5 .2 Fuse Selection
After reprogramming the AC line voltage, be sure one of the following rated
fuses is inserted into the fuse holder before you apply power to the unit:
0.25A Slo-Blo for 100-120 ACV operation
0.125A Slo-Blo for 220-240 ACV operation
