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.
•
Do not touch other switches.
•
Do not turn the switch ON/OFF with excessive force. Doing so may damage the
components and cause malfunction.
•
If electronic components in the iTM are charged with static electricity, it may cause
malfunction. Be sure to discharge the static electricity accumulated in your body before
attempting any operation.
To discharge yourself, touch a grounded metal object (control panel, etc.).
