3.4 Changing Batteries

Changing batteries in the TideMaster is very simple process.
All data is saved in non-volatile Flash memory, so data is secure during the battery change process
The system clock does require battery power in order to maintain the current date and time settings, but the
instrument is fitted with a capacitor system to maintain a supply to the clock for a period of not less than 20
minutes after the removal of the battery. This should be more than sufficient time to allow the battery to be
changed.
In the event that clock settings are lost during battery change, or after an extended period of storage with no
batteries fitted, then please use TideMaster Express or the control panel to reset the clock.
Dry the top of the housing to ensure no water enters the battery compartment during the process.
Undo the thumbscrews on the top of the housing. They are fitted with a retaining clip and cannot be
completely removed.
Gently slide the compartment lid up and out of the battery compartment. The lid is fitted with a retaining
cord.
Remove any residual moisture from around the seal.
Replace the 4 C cell batteries, taking care to insert them in the correct orientation.
Take note of the orientation markings on the battery board. TideMaster will not operate if batteries
are incorrectly installed
Check the O-ring on the battery compartment lid for damage and debris. Clean it and smear lightly with
silicon grease.
Replace the compartment lid and push gently into place. Tighten the thumbscrews – finger tight is sufficient.
For planned periods of extended storage, the batteries should be removed from the instrument to
prevent accidental leakage
