Components which may require replacement on the MSC-250 include the battery and the
firmware. The battery which protects the non-volatile memory must be replaced whenever
the battery voltage drops below 2.6 V. This battery is located at the upper right of the
MSC-250 circuit board (refer to Figure 4.1).

Occasionally, these improvements are significant enough to warrant upgrades to existing
controllers. These upgrades are supplied in the form of new firmware chips which must be
replaced by the customer.
