• The remote control has a built-in backup battery, making the clock function available for 2 weeks in the event of power failure.
If the power failure should last for more than 2 weeks, the current time will need to be reset.

If the indoor unit is switched on or off from the control station or remote control used in conjunction with the timer, the "RUN" indica-
tor will not change.
• If the "RUN" indicator is flashing, this indicates an abnormal condition on the timer.
Check that the cable connections and DIP switch settings are correct. If the "RUN" indicator continues to flash after the check, con-
tact your dealer or HITACHI supplier.
