Getting Acquainted
communications (see “Radio Configuration” on page 2-15 for more
information).
Complete information regarding your radio system can also be found in
the Pacific Crest radio manuals.
Power Board
The internal power board manages receiver power and battery charging,
and is connected to the receiver board and the batteries. The power
board receives power from the internal batteries, even when the receiver
is turned off. This feature allows the internal batteries to charge,
regardless of the receiver’s status (on or off). To prevent the batteries
from discharging when the receiver is stored, put the receiver in Zero
Power Mode (see “Zero Power Mode” on page 4-20 for more
information). The batteries will not charge in this mode.
The power board has a processor and firmware independent of the
receiver card. To ensure firmware compatibility, both the GPS receiver
board and power board must be loaded with firmware from the same
package.
Batteries
Your Prego receiver is equipped with two Lithium-Ion battery packs
connected to the receiver’s power board. Each one of these Lithium-Ion
battery packs is 7.4 V and 5.4 Ah, giving you a total power of 7.4 V,
nominal, and 10.8 Ah when fully charged. With a full charge, the Prego
internal batteries should power both the GPS receiver and the radio
modem for at least 15
working hours. If the internal radio modem is
turned off, the Prego GPS receiver should run at least 20 hours with
fully charged on-board batteries.
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.
A battery charger (AC adapter) is included with the standard package.
See Appendix B for technical specifications on the battery.
