The detector requires a single 9-volt
ALKALINE battery (included).
Do not use ordinary “Zinc
Carbon” batteries.
Do not use “Heavy Duty”
batteries.
Rechargeable batteries can
also be used. If you use
rechargeable, we recommend
using a “Nickel Metal Hydride”
rechargeable battery. The battery
compartment is located on the back
side of the Control Housing. Slide the battery door to the side to remove. Insert
battery (see illustration). Close battery door. When it is time to replace the
battery, simply pull up firmly on the end of the battery.
BATTERY LIFE
Expect 20 to 25 hours of life from a 9-volt alkaline battery. Rechargeable
batteries provide about 8 hours of usage per charge.
BATTERY INDICATOR
The battery icon has three segments plus an outline segment.
The amount of battery voltage for an ALKALINE battery is indicated as follows:
All segments illuminated: 8.0 volts or more
Two segments illuminated, one grey: 7.5 to 7.9 volts
Two segments illuminated: 7.0 to 7.4 volts
One segment illuminated, one grey: 6.5 to 6.9 volts
One segment illuminated: 6.0 to 6.4 volts
One segment grey: 5.5 to 5.9 volts
No segments, flashing outline: less than < 5.5 volts
It is recommended to change the batteries when you see one grey segment.
If using NiMH rechargeable batteries, the display will remain stuck on the
second or third bar for most of the battery life; when it drops to the first bar, the
batteries will go dead within minutes.
SPEAKER VOLUME AND BATTERY CHARGE
You may notice the speaker volume drop while one battery segment is illuminated.
With the outline flashing, low speaker volume will be very apparent.
BATTERY DISPOSAL & RECYCLING
Alkaline batteries may be disposed of in a normal waste receptacle or
recycled. Non-Alkaline batteries should be recycled. In the state of California
all battery types must be recycled. Please refer to local municipalities for
detailed disposal and recycling requirements.
