The normal power source for the 4400 is its internal battery pack. The AC Adapter/
Battery Charger is used to charge the battery. Always charge the battery fully before
use. The 4400 will always operate on the charger and is designed to do so, regardless of
the state of charge of the battery.
Type: Sealed, rechargeable NiMH (Nickel Metal Hydride) cells.
Length of operation: The 4400 can operate on a fully charged battery pack for more
than two (2) hours with the backlight on. When the backlight is turned off, the unit can
operate for more than three (3) hours. For information on how to turn backlight on or
off, see Chapter 4 Instrument Settings - Set Display Preferences on page 4-6.
Charging: The battery pack can be charged by connecting the AC Adapter/Battery
Charger to the 4400. A screen warning will appear during operation when battery
charge is low. A depleted battery pack can be recharged in six (6) hours whether the
unit is on or off. The Battery Charge Indicator glows steadily while charging, and
flashes when fully charged.
NOTE: The Battery Charge Indicator functions whenever the AC Adapter/Battery
Charger is properly connected.
The 4400 can be operated from a 50/60 Hz 120/230V AC power source with or without
the battery pack installed.
Connect the AC Adapter output cable to the Input Connector on the right side of the
4400. Connect the AC Adapter power cord to an appropriate outlet.
Refer to Appendix C for the specifications and replacement of the batteries contained
in 4400.
