Caution –
This product can be used with an externally mounted
antenna of no more than 3db of gain. A minimum separation distance
of 20 cm (approximately 8 in.) must be maintained between the
radiating CDPD antenna and the user for this device to satisfy the
RF Exposure requirements of the FCC
Disclaimer - The instructions included in this section apply to the
cellular antennas sold by Trimble and may not apply to third-party
products. There are many other cellular antennas available on the
market which may or may not be compatible with the
CrossCheck CDPD, including combined GPS/Cellular antenna
solutions which have not yet been tested and certified by Trimble.
Although not as critical as GPS antenna placement, cellular antenna
placement is also important. Mount the cellular whip antenna in a
vertical orientation in a location where it is safe from damage during
normal vehicle operation and maintenance. Automated vehicle washes
may damage misplaced cellular antennas.
