2.3 F3Ci Preparation
To prepare the detector for use, conduct the following procedure:
a. Open the Hard Case and/or Soft Carry Bag.
b. Remove the detector and inspect for obvious signs of damage.
If damage is evident, report to the supervisor/team leader.
c. Unlock the Battery Compartment Lid by twisting the Battery
Lock Lever counter clockwise one-quarter turn. Once unlocked,
pull the lid away from the Battery Compartment (the lid will stay
attached by a tether as shown in Figure 4).
d. Using the battery map located on the side of the Main Body,
insert four C cell batteries. Taking care not to snag or trap the
tether, replace the Battery Compartment Lid and rotate the
Battery Lock Lever clockwise one-quarter turn. If the batteries
are inserted incorrectly, the detector will fail to function when
switched on.
e. Using Figure 5 as a guide, unfold and adjust the F3Ci.

NOTE
The F3Ci requires 4 C cell batteries for operation. Use only high
quality alkaline or rechargeable batteries. Minelab recommends that
only rechargeable batteries with a capacity of 5000 mAh or greater
be used with the F3Ci. Rechargeable batteries have specific charge/
discharge maintenance requirements, which should be strictly
followed to ensure maximum battery life.
