Power Adapter Intended Use
Propaq Encore Reference Guide 121 Welch Allyn
Procedure
1. Unplug the power adapter’s removable cord from the ac mains outlet and the power
adapter.
2. Turn the power adapter so you can see the window that indicates the voltage setting.
3. Using a small, flat-blade screwdriver, carefully pry the fuse module from the power
adapter.
4. Replace both fuses with the specified type.
Both fuses should be replaced at the same time, even if only one fuse has
opened due to an overcurrent situation. The unopened fuse may have been
stressed and could become unreliable.
Caution Spare fuses are contained in housings next to the fuses in the fuse
module as shown in the following picture. Between the fuses is a small
printed-circuit board (PCB) that sets the power adapter to the desired ac
mains voltage. When handling the fuse module, the PCB may slide out.
If the small PCB between the fuses has slipped out of place, slide it back into
place in the fuse module, and verify that the voltage setting indicated in the
window on the fuse module is correct. If the voltage setting is incorrect, simply
slide the PCB out of the fuse module, rotate it 180° and slide it back into place.
