Using the
Standard Battery Holder
1. Slide open the battery holder lid (decal side of
battery holder) by applying gentle upward
pressure on the tab of the door so that it unlocks.
Slide the door away from the battery box
exposing the cell positions.
2. Remove any old cells from the holder. Note the
(+) and (-) positions of each cell and the (+)
and (-) for each position marked inside the cell
tray. Install new “AA” cells noting carefully the
correct (+) and (-) positions.
If the cells are installed incorrectly, the detector
may require service by an Authorized
Service Center.
3. Slide the door closed so that it snaps securely.
4. Insert the battery holder into the detector so that
the decal is facing down, with the battery
holder door tab and metal contact points facing
toward the inside of the battery compartment.
Close the battery compartment door and secure
the two latches on the bottom of the case. Hook
the front of each latch fi rst, then press down on the
rear.
Standard Battery Holder
1. The standard battery holder holds eight “AA”
cell batteries equalling 12 volts total. Alkalines
are recommended for use with this model. During
normal searching conditions you can expect about
40 hours of hunting time from a quality set of eight
alkaline batteries.
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 to about 30-35
hours.
3. The battery voltage appears automatically on the
display when the Gain is used to turn the MXT 300
"ON". Once the batteries become weak (8 volts)
"Lo Bat" will automatically appear on the display
during searching. At that point the batteries should
be replaced. Alkalines provide some reserve time
after "Lo Bat" appears, rechargeable do not.
4. The battery compartment opens by gently pull-
ing 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.
