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.
