Battery Hatch and Hatch Retaining Ring Installation
• Replace the Hatch O-ring with a new one. This O-ring must be a genuine Sherwood Scuba part
that can be purchased from an Authorized Sherwood Scuba Dealer. Use of any other O-ring
will void the warranty.
• Lightly lubricate the new Hatch O-ring with silicone grease and place it on the inner rim of the
Battery Hatch. Ensure that it is evenly seated.
• Slide the Hatch Retaining Ring, top portion first (small opening), onto your thumb (Fig. 81).
• Carefully place the Battery Hatch (with O-ring) into position on the rim of the Battery Compart-
ment, then press it evenly and completely down into place with your same thumb.
• Maintain the Battery Hatch securely in place and, using your other hand, slide the Retaining
Ring down off your thumb and into position around the Battery Compartment.
• The tabs on the Retaining Ring fit down into the two slots located at the 2 and 8 o'clock posi-
tions.
• Using your fingers, turn the Ring counter clockwise 5 degrees until the tabs engage (Fig. 82),
then tighten it 5 more degrees by turning it counter clockwise with the aide of a small blade
screwdriver (Fig. 83).
NOTE: While tightening (turning) the Retaining Ring, exert continuous inward
pressure on it until it is secured in the proper position. A small symbol located
on the Ring should be aligned with the Locked symbol located on the Housing
(Fig. 83 a/b)
