f. Using the battery maps, located on the side of the Battery Pack
and on the inside of the Battery Pack Lid, insert four D cell
batteries. Replace the Battery Pack Lid and rotate the Battery
Lock Lever clockwise one-quarter turn. If the batteries are
inserted incorrectly, the F3 will fail to function when switched on.
NOTE
The F3 requires 4 D cell batteries for operation. Use only high
quality alkaline (LR20) or rechargeable batteries. Minelab
recommends that only rechargeable batteries with a capacity of
4000 mAH or greater be used with the F3. Rechargeable batteries
have specific charge/discharge maintenance requirements, which
should be strictly followed to ensure maximum battery life. Only
NiCad and NiMh type D cell rechargeable batteries are suitable for
use with the F3.
