Note Be careful not to pull up on the chart recorder arm while changing paper.

buttons. This may cause permanent damage to the recorder.
The recorder normally uses AC power when the system is operating. If AC power
fails, the LED indicator on the recorder flashes to alert you to a power failure.
The recorder continues sensing cabinet temperature and the chart continues
turning for approximately 24 hours with back-up power provided by the
nine-volt battery.
The LED indicator glows continuously when main power is functioning and the
battery is charged.
When the battery is low, the LED flashes to indicate that the battery needs to be
changed.
