9. Changing the WP-Sim Battery
1. Turn the instrument over and locate the 6 Instrument Case Screws
on the rear. See the diagram below.

CAUTION : THERE ARE WIRES THAT CONNECT THE CIRCUIT
BOARD TO THE CONNECTORS. TAKE CARE WHEN OPENING
THE METER TO ENSURE THESE WIRES ARE NOT BROKEN.
Do not lose the nylon washers, as these form a part of the waterproof
seal when the screws are replaced.

WP-Sim
and replace the Instrument Case
