The detector requires two AA batteries.
We recommend ALKALINE batteries
(not included).
Do not use ordinary “Zinc
Carbon” batteries.
Do not use “Heavy Duty” batteries.
Rechargeable batteries can also be
used. If you use rechargeables, we
recommend using a “Nickel Metal
Hydride” rechargeable battery. The
battery compartment is located on
the right side of the Control Housing.
Both batteries should be installed with
the negative terminal down.
Remove battery tube:
1. Slide the battery door off.
2. Extend the handle on the battery tube (with your finger or by using the tab
on the battery door to pry the handle into the extended position)
3. Pull on the handle to remove (do not use the battery door tab to pull the tube
out of the control housing, as this may cause damage to the battery door)
To install battery tube:
1. Position the handle on the battery tube in the lowered position.
2. Firmly push down on the battery tube, until the battery tube handle is
flushed with the housing. (The battery tube will only insert one way, with the
brass contacts facing towards the display and the hinged side of the handle
towards the back.)
BATTERY LIFE
Expect 25 to 30 hours of life from 2 AA Alkaline batteries. Rechargeable
batteries provide about 15 hours of usage per charge. Backlight increases
power consumption and decreases battery life, with significant power drain at
maximum brightness.
BATTERY INDICATOR
The battery icon has three segments plus an outline segment. The amount of
battery voltage for two ALKALINE batteries is indicated as follows:
All segments black: >2.8 volts
Right segment grey, other two black: >2.6 volts
Right segment off, other two black: >2.4 volts
Right segment off, mid grey, left black: >2.2 volts
Right and mid segments off, left black: >2.0 volts
Right and mid segments off, left grey: >1.8 volts
All segments off, outline flashing: < 1.8 volts
It is recommended to change the batteries when you see the one black segment.
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. Other battery chemistries should be recycled.
