Standard Battery Holder
1. The standard battery holder (blue decal) holds
eight “AA” cell batteries. Alkalines are recom-
mended for use with this battery holder.
2. Non-alkaline batteries can be used in this holder.
When non-alkalines or rechargeable “AA”
cells are used, detecting time (before replacement/
recharge) may be reduced.
3. "LOW BAT" will automatically appear on the
display when the batteries become too low to
properly operate the detector.
4. The battery compartment opens by gently
pulling down on the front of each of the two
latches (on the bottom of the control box) releasing
the catch and hinging open the door.
The non-rechargeable battery holder can use many
different types of batteries, including rechargeable.
This holder is designed for standard size penlight
"AA" batteries which should be 50 mm
±
.10mm.
Battery lengths shorter than this will likely cause
problems with this power supply.
When the instrument is turned on the battery volt-
age will momentarily appear after the opening
display. The detector will then continue to the
MAIN MENU. To recheck the battery voltage
during operation, squeeze and hold the TRIGGER
and press the ARROW DOWN control.
