WARNING
The use of these preset frequencies without a
license is illegal. Contact your local
authorities (the FCC in the US) to use these
preset frequencies.
Once the FCC, or your local authority, issues the proper
licenses, your TPS dealer will program your PDL radios
(Base and Rover) to enable communications.
Complete information regarding your radio system can also
be found in your radio modem documentation.
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 4-22 for more information). The batteries will not
charge in this mode.
The power board’s processor and firmware are independent
of the receiver card. To ensure firmware compatibility, the
GPS receiver board and power board must be loaded with
firmware from the same package.
