• Place a new 3.6 volt TADIRAN
®
, model TL-2150, .95Ah, 1.0ma, Lithium
battery, negative end first, into the battery compartment toward the
spring, ensuring proper orientation of the positive (+) and negative (-)
ends (Fig. 80).
• Carefully place the battery hatch into position so that it seats on top of
the o-ring, and while holding it in place with your thumb, secure it with
the four screws by turning them clockwise with a small Philips head
screwdriver. DO NOT attempt to use any other screws.
• Carefully tighten the screws until secure by alternately turning them each
one turn at a time. Turn the upper left, then the lower right, then the
lower left, then the upper right.
• Repeat the sequence until all of the screws are evenly secure. The outer
surface of the battery hatch should be flush with the outer surface of the
housing. DO NOT overtighten.
INSPECTION
• Activate the unit and watch carefully as it performs a full diagnostic and
battery check and enters Surface Mode.
• Observe the LCD display to ensure it is consistently clear and sharp in
contrast throughout the screen.
• If any portions of the display are missing or appear dim, or if a Low Bat-
tery condition is indicated, return the unit to your Authorized Oceanic
Dealer for a complete evaluation before attempting to use it.
