CO is detected.
W arning occurs if
the sensor detects
acceptable but
increasing CO
levels.
Pulsed signal 10 Hz 0sec 10 sec N/A Ensure windows are open for proper
ventilation.
Operate the blower to expel
dangerous fumes.
Move the vessel away from other
vessels (as another vessel may be the
source for the presence of the CO).
Check the generator exhaust system
(see Section 3.6).
Contact an authorized
distributor/dealer for service.

system.
Check t he oil level and add oil if the
level is low.
