The WX-167 uses 5 AA batteries for back-up power.
It can run on non-rechargeable alkaline, or
rechargeable Nickel Cadmium (Ni-Cad) or Nickel
Metal Hydride (NiMH) batteries. Use the slide switch
located inside the battery compartment (Fig. 1) to
select the battery type. To select “Alkaline” when
alkaline batteries are installed, push the switch to the
right. To select “Ni-Cad” when using rechargeable
batteries, push the switch to the left. (See Fig. 1). It is
recommended that rechargeable batteries be
replaced every three years.
DO NOT CHARGE ALKALINE BATTERIES!
Always set the battery select switch to “Alkaline”
before installing alkaline batteries. Using the
“NiCad” setting with alkaline batteries may cause
a fire hazard.

hours of operation time. To maintain maximum backup
time, do not disconnect AC power supply from the unit
while in use. Remove the batteries when the unit
