113 °F}. The "Thermal error" is displayed based on the internal
thermal information of the HDD. If the "Thermal error" indication is
displayed, it is recommended to change the installation environ-
ment so that the ambient temperature is maintained at approx.
+25 °C {77 °F}. When the "Thermal error" indication is displayed
frequently, contact your dealer.
• Check if the fan is malfunctioning.
• Check if the recorder ventilation holes or cooling fan are blocked,
and also check for dust collected around the ventilation holes.
• The clock function of the recorder is accurate within ±30 seconds
per month.
To keep the correct recording, set the time periodically, or enable
the auto time adjustment function on the rear panel terminal, or
configure the system using the NTP function so as to keep the cor-
rect current time.

devices to the same UPS.
• Make sure that the HDD unit is inserted all the way into the HDD slot.
• The hard disk drive is faulty.
• Initialize an applicable extension unit.
• When operating the recorder in RAID5 mode, attach three or more
HDDs in the extension unit. If the recorder is being operated in
RAID6 mode, attach four or more HDDs in the extension unit. Then,
connect to the recorder and turn on the power of the extension unit
first, and later turn on the power of the recorder.
