Primary or backup display switch pushes are either unresponsive or produce incorrect/unusual results.


Suspect a broken switch. First push the suspected switch in fully and hold in. Second remove the wire C clip with a dental spike. Third carefully release the switch and remove it and the switch spring. If the switch is broken into 2 parts replace it. If the switch is not broken first check the second switch in the display in question. If neither switch is broken replace both and test as a switch may loose its magnetism. If no switches are broken and replacing switches does not solve the problem suspect Reed switch damage and contact Avon Underwater Systems for advice.
