802 AWE Operation Manual
Advanced Wireless Test Set
Battery Charging
Before you can use your instrument, you will need to charge its batteries. Your instrument’s
Li-Ion batteries (two internal) provide approximately 6 hours of power during continuous
operation.
The instrument comes with a AC to DC Power Adapter & Battery Charger which can be used
to charge the batteries in approximately 6 hours or to trickle charge the batteries while the
instrument is in use.
Plug the power adapter & battery charger into the DC charge port of the 802 AWE on the
bottom of the instrument under a protective cover.
Your instrument is equipped with a “smart” battery charging circuit so that the charging method
(fast or trickle) is an auto function. Fast Charge is used to charge the battery quickly. Trickle
Charge is used to keep the battery fully charged.
Every time your instrument is plugged into the charging cube, it starts charging automatically
via the Trickle Charge method. If the unit determines Fast Charge is necessary, it defaults to
the Fast Charge method.

The Title Bar at the top of the 802 AWE screen displays the battery voltage and the
following charging status icons:

3.50 VDC or approximately 50% of battery capacity.
25% Charge – This icon is displayed when the 802 AWE battery is at a minimum of
3.40 VDC or approximately 25% of battery capacity. When the battery charge drops
to this level, it is recommended that the battery is charged soon.
0% Charge – This icon is displayed when the 802 AWE battery is less than 3.40
VDC or approximately 0% of battery capacity. When the battery charge drops to this
