Memory Backup
A 3.0 VDC lithium battery maintains a real-time clock for four to five years. This
battery is used when external and internal power is not available.
The NET-PATHm provides non-volatile data storage using flash memory technology.
Flash memory does not require a power source to retain stored data.
MTBF
Mean-Time-Between-Failure (MTBF) is in excess of 60,000 hours, per Bell IP 10425.
Battery Backup
When fully charged, a 12 VDC rechargeable battery provides full operation for two
hours.
Battery Charge Time
The battery requires five minutes of charging for each minute of battery use. For
example, a battery used for thirty minutes needs approximately two and one half hours
to fully recharge.
