Powering the Prego
You can power the Prego using:
• Internal batteries
• External batteries
• A battery charger
Internal batteries
With a full charge, the Prego internal batteries should power both the GPS
receiver and the radio-modem for not less than 15
working hours. If the
internal radio modem is turned off, the Prego GPS receiver should run not
less than 20 hours with fully charged on-board batteries.
1. Plug the power/charger cable into the power input port.
2. Plug the power/charger cable into an available outlet.
3. Press the Reset key on the receiver. This will ensure that the receiver is
in Normal mode for charging. The receiver will not charge in Zero
Power Mode (see “Zero Power Mode” on page 4-20 for more
information).
4. Leave overnight. An eight-hour charge will charge the batteries about
90%. A ten-hour charge will fully charge the receiver. The internal
batteries cannot be overcharged.
The speed of the charge depends on Power and Charger settings on the
PCView Receiver Configuration screen and whether the receiver and
controller are turned off or on. See “Power Management” on page 2-10 for
more information.
The Li-Ion batteries used in the Prego should run at no less than 98%
capacity after 500 charging cycles. These batteries do not need to be drained
before recharging.
External Batteries
In addition to the internal batteries, you can use your Prego with external
batteries. The use of external batteries allows you to continue using the
receiver in case the internal batteries are discharged. To use external
batteries, you must have:
• a 12 V and 2.3 A*h battery
