FEATURE LIST

The C-350 computers use a common LR44 1.5v button cell battery. Replacement
batteries are available at most camera shops and from your Vetta retailer. Under
normal usage a battery should last approximately one year.
NOTE: Most prob-
lems that occur with cycle computers are caused by dead or weak batteries. If
you are having problems with your computer's operation, check and replace the
battery first.
STEP 1
Remove the battery cover from the bottom of the computer by turning the
battery cap counterclockwise with a coin.
STEP 2
Install the battery into the battery compartment with the positive (+) side of the
battery facing the compartment door. Be careful when you are installing the
battery not to bend any of the battery contacts.
STEP 3
Screw the battery cap firmly into place. Make sure that the rubber o-ring seal
does not get pinched or distorted in this operation as this may compromise the
waterproofing of the unit.
