34 Preventive maintenance

The system requires minimum maintenance. To keep the system in good condition, do the following:

34.1 Clean air inlets

The power amplifiers can collect dust as a result of the internal fans. Once a year you should use a vacuum cleaner to clean the air inlets of all units in the 19-inch racks.

34.2 Change battery

The battery on the main board of the network controller needs to be replaced before failure. Once every eight years, change the battery. The battery is a 3.0 V type CR2032. Unpower the unit before changing the battery. After replacing the battery, the time and date settings of the PRS-NCO-B will be lost and must be re-entered (see section 5.6.8).
