Getting to Know Your Maxor
Your Maxor may be equipped with one of the following communication boards
(however, your receiver may also be configured without a radio/modem):
• UHF modem – a Pacific Crest PDL (Positioning Data Link) modem; either a 450-
470 MHz or 430-450 MHz; receiving only.
• GSM – dual-band, dual-user cell phone frequency modem (Europe and Japan: 900/
1800 MHz; USA and Canada: 900/1900 MHz).
Notice: To comply with RF exposure requirements, maintain at
least 20cm between the user and the GSM radio modem.
The Base station operator is responsible for complying with local regulations for radio
operation. In the US, the FCC regulates the use of radio transmitters, requiring a license.
Broadcasting without a license can result in severe penalties including the confiscation
of your radio and GNSS equipment. Please call JNS Customer Support if you need
advice on obtaining the proper license in the USA.
The internal radio modem comes with a number of preset frequencies programmed at
JNS.
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 JNS 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 4-16 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.
