Introduction
The normal power source for the PX5 is its internal battery pack. The AC Adapter/
Battery Charger is used to charge the battery. Always charge the battery fully before
use. PX5 will always operate on the charger and is designed to do so, regardless of the
state of charge of the battery.
Battery pack
Type:
Sealed, rechargeable NiMH (Nickel Metal Hydride) cells.
Length of operation
: PX5 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

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.
