Cause/solution
• Check if the fan is malfunctioning.
• Check if the the ventilation openings or the cooling fan of the
recorder is blocked, and also check for dust collected around the
ventilation openings.
• The ambient operating temperature is +5 °C to +45 °C {41 °F to
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.
• 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 termi-
nal, or configure the system using the NTP function so as to keep
the correct current time.
• Has the built-in battery sufficiently been charged?
Charge the built-in backup battery by turning on the power for 48
hours or more.
• Is the built-in backup battery depleted?
The built-in battery life is around 5 years as an indication of replace-
ment. (Lifetime may be shortened depending on the use environ-
ment.)
• The hard disk drive is faulty. Contact your dealer.
• Is a recommended SD memory card used?
• Some SD memory cards cannot be used with this recorder. It is
recommended to use Panasonic's SD memory card.
• Is the SD memory card formatted?
• Are data copied to the SD memory card?
• The power cord, connector, or power plug is damaged.
This may result in electric shock or a fire.
Unplug the power plug from the AC outlet immediately, and
refer to qualified service personnel.
