9.4.3. Replacing the transmitter battery
To change the transmitter battery:
1.
Remove the transmitter from the regulator HP port.
2. Unscrew and remove the four Phillips screws on the back of the transmitter.
3. Pull off the transmitter cover.
4. Carefully remove the O-ring. Be careful not to damage the sealing surfaces.
5. Carefully remove the battery. Do not touch the electrical contacts or the circuit
board.
Check for any traces of leakage, or for any other damage. If there is a leak or any
other damage, take the transmitter to an authorized Suunto representative or
distributor for checking and repair.
6. Check the condition of the O-ring. A defective O-ring may indicate sealing or
other problems. Dispose of the old O-ring, even if it seems to be in good condition
7. Check that the O-ring groove and the sealing surface of the cover are clean. Clean
them with a soft cloth if necessary.
8. Gently insert the new battery into the battery compartment. Check the polarity of
the battery. The "+" mark should point toward the top of the compartment and the
"-" mark towards the bottom.
NOTE
It is imperative that you wait at least 30 seconds before re-
installing the transmitter battery.
