F3 Preparation
To prepare the F3 for operations the following procedure should be followed:
• Open the Hard Case or Soft Carry Bag.
• Remove the F3 and inspect for obvious signs of damage.
• Check that the correct Sensitivity Endcap is selected and mounted
correctly. (Changing Endcaps discussed in Slide 10).
• Battery Pack and Inserting Batteries
o Invert the F3 being careful to rest the Endcap either inside the
Hard Case or Soft Carry Bag to keep it clear of dirt, remove the
Battery Pack and insert four D Cell batteries as follows:
P0615-A
Battery
Map
Battery
Pack
Battery
Pack Lid
Battery
Lock
Lever
o Carefully unlock the Battery Pack Lid by rotating the Battery Lock
Lever counter clockwise one-quarter turn. Once unlocked,
carefully pull the lid away from the Battery Pack (the lid will stay
attached to the Battery Pack by a tether).
o 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.
o If the Battery Pack was removed (Note: removal of the Battery
Pack to replace batteries is not necessary) ensure that the Lock
Lever at the front of the Electronics Pack is in the unlocked
position and position the Battery Pack on the rail underneath the
Upper Shaft.
