Always activate the CO detectors when the boat's engines or generator
are running. Carbon monoxide is dangerous. Refer to Section 1 - Carbon
Monoxide (CO) Warnings for information on minimizing, detecting and
controlling carbon monoxide accumulation.
When the CO detectors are operating, they alert you to the presence of carbon
monoxide in the cabin by emitting a loud, high-pitched sound. If you hear this
alarm, determine the cause of the CO accumulation and correct it immediately.
There is a test button on each CO detector. Test each unit on a weekly basis.
If you suspect that a CO detector is faulty, have your dealer repair or replace
it immediately. Refer to Section 1 - Carbon Monoxide (CO) Warnings for more
information on CO.
