Battery Installation
The WX-150 uses 4 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. When the radio is operating on battery power, the green READY light will blink.
Use the slide switch located inside the battery compartment to select the battery type.
(See Fig. 1) When alkaline batteries are installed, push the switch down to select
“ALK” When using rechargeable batteries, push the switch up to select “CHG”. It is
recommended that rechargeable batteries be replaced every three years.
DO NOT CHARGE ALKALINE BATTERIES!
Always set the battery select switch to “ALK” before installing alkaline batteries.
Using the “CHG” setting with alkaline batteries may
cause batteries to leak and present a a fire hazard.
To install or replace the batteries:
- Turn the unit upside down. Locate the battery
compartment door tab (Fig. 2), press down on the door
tab and lift the cover up to open
- Insert the batteries into the battery compartment.
Be sure to follow the polarity markings. (Fig. 3)
- Set the battery charging switch to ALK for non-
rechargeable alkaline batteries. Set it to CHG for NiCad
rechargable batteries.
- Replace the cover.
NOTES: Rechargeable batteries must be charged for
at least 24 hours before they are ready. Rechargeable
batteries provide approximately 15 to 20 hours of
operation time. Non-rechargeable alkaline batteries will
provide over 50 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 is not used for a prolonged period of time.
