㩷 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.

Note䋺 For models with electric locking, an unlock key is provided in order to unlock the door during a power interruption or in case the electric lock fails. Always store this key in a safe place. It is recommended that you make a note of the key symbol and number in case the key is lost.
WARN ING
Do not use the unlock key to unlock the door during H2O2 decontamination or during H2O2 gas analysis by UV. Doing so may cause harm to health from H2O2 gas leakage.
