Console - bend the rubber console boot back to expose the edge of the module.
If the boot is flexible enough to permit, you may bend it back far enough to
scoop the module out with your index finger. Otherwise, it may be necessary
to insert a blunt screwdriver until the tip rests just underneath the module.
DO NOT pry the module from the console! Slowly increase the pressure under
the module by releasing the tension on the rubber boot. The module will slide
up the screwdriver and exit the console.

BATTERY REMOVAL

The battery compartment should only be opened in a dry and clean environ-
ment, with extreme care taken to prevent the entrance of moisture or dust.
Examine the case back to find the Battery Hatch (Fig. 70a):
• Remove the three screws that secure the battery hatch to the housing by
turning counter clockwise with a small philips head screwdriver.
• Lift the hatch up and out of the housing.
• Lift the battery, positive (+) end first, out of the battery compartment.
• Remove the battery hatch o-ring and inspect it for any signs of deteriora-
tion or deformity. DO NOT use tools to remove the o-ring.
• O-ring replacement is highly recommended to ensure proper sealing.
• Check the battery hatch and housing sealing surfaces for any signs of
damage which might impair proper sealing, and the inside of the battery
compartment for any signs of corrosion indicating entrance of moisture.
