BATTERY TEST

GENERAL: The BW DEFENDER continuously monitors the performance and

condition of its battery. During normal operation, the unit displays “Battery OK” in the

bottom left hand corner of the LCD display.

LOW BATTERY ALARM: Should the unit

detect a battery in the early stages of

running down, the unit will emit a low

battery warning alarm. (See page 14.) This

warning will persist until the battery in the

unit is replaced, or the battery is nearly

dead.

If the low battery condition persists long

enough, the battery will be in danger of

running down to the point where the unit

can no longer accurately measure gas.

Once this happens, the unit will execute an

automatic shutdown (see below).

AUTOMATIC SHUTDOWN

AUTO-SHUTDOWN: Should the battery

be in immediate danger of dropping below

the minimum operating voltage, the

BW DEFENDER will automatically shut

down. Auto-Shutdown is preceded by

approximately 30 minutes of low battery

alarm.

Auto-Shutdown is announced by:

a) 8 beeps and flashing alarm LED's.

b) The unit will turn off the LCD display

except for the “BATTERY LOW” icon,

which will flash periodically to remind

you that the unit is in need of a charged

battery.
