2.4.5. Other Considerations
NexLog 740
: The recorder is shipped with two keys for locking and unlocking
the front door of the recorder. One key should be kept in a safe place as a
backup spare. You should consider preventing casual access to the other key as
well. The switch behind the front panel should be used to power up the recorder
only and not be used to power down the recorder unless absolutely necessary.
The logger should be shut off using the SETUP/Power Off option. Otherwise,
data corruption could occur. If it is necessary to use the switch to shut down
the recorder, hold it for one second and release.
Do not continue holding it until
the recorder shuts down

2.4.6. Connecting AC Power and UPS (Uninterruptible Power Supply)
The recorders use “universal” power supplies. This means you can plug the
recorder into any line (mains) voltage from 100 volts to 240 volts nominal.
However, to prevent unplanned shutdowns caused by power glitches or
interruptions, Eventide strongly recommends the use of an Uninterruptible
Power Supply (UPS) unit that meets certain minimum characteristics:
The UPS must provide power for a long enough period to allow orderly shutdown
of the recorder in case of power failure.
If your facility has a backup generator, the UPS should provide power long
enough to operate the recorder until the generator becomes operational
following the start of a power failure (typically a minute or less) PLUS a period
long enough to allow orderly shutdown of the recorder in case of generator
failure.
The UPS should be an approved model, i.e., one that can communicate its
status to the recorder. This isn’t strictly necessary if your facility is manned and
personnel are trained to shut down the recorder using the appropriate
procedure in case of power failure before the UPS battery drains. However, an
