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.
When the battery is re-installed, the transmitter sends an overpressure (“---“)
signal on code 12 for 10 seconds, after which it goes to normal operation, and
shuts down after five (5) minutes.
9. Check that the new lubricated O-ring is in good condition. Put it in the right position
in the O-ring groove. Be very careful not to get any dirt on the O-ring or its sealing
surfaces.
10. Carefully put the transmitter cover into place. Note that the cover will only fit in
one position. Match the three slots on the inside of the cover with the three ledges
below the battery.
11. Screw the four screws back into place.
