Sanyo MCO-19AIC(UV) Instruction Manual page 48

The buzzer can be stopped by pressing the BUZZER Key, but remote alarms will not stop. In addition, a
buzzer that sounds because of the upper limit temperature alarm cannot be stopped by pressing the
BUZZER Key.
Err01 recovery is achieved automatically by correctly connecting the gas and pressing the BUZZER Key
to stop the buzzer. In addition, when the MCO-21GC is installed and the gas supply is switched to the
reserve gas cylinder, press the BUZZER Key and replace the gas cylinder.
If an error from Err05 to Err18 occurs (except for the upper limit temperature alarm in Err13 to Err16),
then consult a Sanyo sales representative or agent.
