Battery Charging
Before you can use your instrument, you will need charge its battery. Your instrument’s
Li-Ion battery (one internal) provides approximately 4 to 5 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 battery in approximately 4 hours or to trickle charge the battery while the instrument
is in use.
Plug the power adapter & battery charger into the DC charge port of the 180 DSP 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 180 DSP screen displays the battery voltage and the
following charging status icons:

charging, the battery voltage will be shown between 12 and 14 VDC (dependent on
charging source).
100% Charge – This icon is displayed when the 180 DSP battery is charged from a
minimum of 7.50 VDC or approximately 100% of battery capacity.
75% Charge – This icon is displayed when the 180 DSP battery is charged from a
minimum of 7.25 VDC or approximately 75% of battery capacity.
50% Charge – This icon is displayed when the 180 DSP battery is charged from a
minimum of 7.00 VDC or approximately 50% of battery capacity.
25% Charge – This icon is displayed when the 180 DSP battery is charged from a
minimum of 6.50 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 180 DSP battery is charged to less
