REPLACEMENT OF THE BATTERY
Replace the battery for the power-failure alarm every 3 years (when “Please exchange a battery.” is
displayed in the message column) to ensure the alarm will operate in the event of a power failure.
Contact our sales representative or agent to arrange the replacement of the battery when “Please
exchange a battery.” is displayed in the message column.
The alarm function (blinking of alarm indicator, sounding of buzzer) will not operate when the battery for
the power-failure alarm is flat.
The alarm indicator blinks and the buzzer sounds as a result of power from the battery for the
power-failure alarm. The regular replacement of the battery for the power-failure alarm is important to
prevent an increase in chamber temperature in the event of unexpected circumstances.
<Important>
The used battery is a recyclable resource. Do not dispose of the battery. Always follow the procedure
for recycling.
