Power Supply - PC SignalHawk
Internal Battery
The PC SignalHawk has an internal, rechargeable, lithium-ion battery
pack that will operate the unit for a minimum of 3 hours of continuous
use. Recharging time, from a full discharge, is approximately 4 hours.
Note:
When the unit is shipped from the factory, the
battery may not be fully charged. Use an AC adapter when
operating the unit for the first time.
Power Adapters
The PC SignalHawk can be operated using the supplied AC adapter or
a 12V automobile cigarette lighter adapter. Using these adapters will
also charge the internal battery.
Note:
The charge LED will be steady amber while charg-
ing and steady green when fully charged.
Charge Indicator Light
The charge indicator light on the PC SignalHawk has a dual function.
When the yellow light comes on, the PC SignalHawk has approxi-
mately 1 to 1.5 hrs of operation left depending on temperature and
battery age. At this time, the unit should be charged or the battery
should be replaced. See “Charging the Battery” on page 81 or "Replac-
ing the Battery on the PC SignalHawk" on page 81.
Note:
To avoid damage to the battery pack, the unit will
shut-off completely when the battery charge falls below 10%. If
this occurs, the battery must be charged to a minimum voltage
before the unit is allowed to resume operation. Full recharging
is recommended.
Note:
When using the supplied car charging adaptor, a
minimum voltage of 11.5V is required overcome the safety cir-
cuit and allow it to be operational. To ensure complete charg-
ing, at least 13V must be present at the DC input.
WARNING
When using the AC adapter, connect the AC plug only to a properly
grounded receptacle. Serious injury or death can occur if not
properly grounded.
