Turning ON/OFF the Internal Battery

The iTM is equipped with an internal battery to feed the clock during power failures and shutdown.
The internal battery is turned ON/OFF by using the BACKUP switch (1). The BACKUP switch is
located beneath the screwed cover that appears when the unit's sliding front cover is moved. (See
figure below.) Normally, it is set to ON.
When Turning OFF the Unit for a Long Time
When leaving the controller turned OFF for a long time (6 months or more), set the BACKUP switch
to OFF.
(Setting this switch to OFF does not erase area/management point settings, schedules, etc.)
• If power is not supplied to the iTM for a long time, the battery may discharge completely.
• When starting to use the iTM again, set the BACKUP switch to ON.
CAUTION
• Do not touch other switches.
• Do not turn the switch ON/OFF with excessive force. Doing so may damage the
components and cause malfunction.
• The iTM contains static-sensitive components.
To prevent electrostatic discharge damage to these components, discharge the static
electricity accumulated in your body before attempting operation.
You can discharge static electricity accumulated in your body by touching a grounded
metal part of the unit (control panel etc.).
