Start-Up and Use

Menu Items 8 and beyond are for use only by qualified service

technicians. Information about these options is available in the

NPB-290 service manual.

BATTERY OPERATION

The NPB-290 has an internal battery that may be used to power

the monitor during transport or when AC power is not available.

A new, fully charged battery provides a minimum of 8 hours of

monitoring time if there are no alarms or serial or analog output

devices connected.

Note: Whenever the monitor is connected to AC power, the

battery is being charged. Therefore, it is recommended

that the monitor remain connected to AC power when not

in use. This makes available a fully charged battery for

use at any time.

A completely discharged battery can be fully recharged in

approximately 14 hours, whether the monitor is turned on or off.

Since the monitor cannot operate with a dead battery, before

attempting to turn on an NPB-290 whose battery charge has been

depleted, first plug the monitor into an AC outlet to allow the

battery to charge for a few minutes. The monitor then may be

powered on.

Low Battery Indicator

When 15 minutes or less of monitoring time is available on the

existing battery charge, the Low Battery indicator lights and a

low priority alarm sounds. This alarm is unsilenceable while

running on battery power. Connect to AC power to silence the

alarm.

Note: If the AC voltage selector switch on the rear panel does

not match your AC voltage source, the monitor may run

on battery power, even though it is plugged in, which will

eventually result in a low priority alarm and a lighted low

battery indicator. Ensure that the switch setting matches

your AC voltage source.

If the monitor is not connected to AC power within

approximately 15 minutes, it shuts down.
