3. Either snug the Battery Cap in a small vise, or using a second pair of vise grips to
hold the cap, grip the drive screw in the cap and with a counter-clockwise twisting
motion, gently remove the old drive screw from battery cap. Discard the Drive Screw,
but set aside the spacing washer.
4. Slide the new lanyard cable and spacing washer on the new Drive Screw, then use a
pair of vice grips to press the new Drive Screw into the MM400B case until it stops.
Be careful not to scratch the MM400B case.
The drive screw should not seat completely; if it does, the lanyard may not rotate freely. If the lanyard
binds, or does not turn freely, pull the drive screw out a small amount in the same manner as the drive
screws were removed.
Important
The spacing washer must be placed between the cable lanyard and the battery cap & case as shown to function correctly.

same manner as the drive screws were removed.
Important
The spacing washer must be placed between the cable lanyard and the battery cap & case as shown to function correctly.
