User's manual System Amplifier K&F TOPAS 7. Service 7.1 Hardware 7.1.1 Replace/Clean the Air Filters The device is equipped with three fans and air filters. To clean the air filters, remove both front panel lids and take out the air filter elements. Remove any dust by tapping on the filter or blowing the dust out. If you cannot clean the air filters, you can order them as replacement parts from your dealer. Please do not use any arbitrary foam filter that you have cut to size since the airflow and a functional cooling system could no longer be guaranteed. Do not use any cleansers containing solvents. 7.1.2 Replacing the Fuse The device’s power supply unit is internally protected with a fuse. A blown fuse indicates an error in the device. Only trained specialised personnel may replace it with the same type of fuse. Warning 7.1.3 Replacing the Backup Battery of the Real Time Clock The device is equipped with a lithium battery as a backup for the real time clock. The life span of the battery is approx. 10 - 15 years. Your supplier can change the battery when this becomes necessary. The battery may not be replaced by a different type.
