ITC 220 Base Station, Locomotive & Wayside Radio Transceiver Field Service Guide PN 0046300120 Rev. A
| Page 14
Radio transceivers are intended for use by railroad employees who have full knowledge of their exposure and can
exercise control over their exposure to meet FCC and IC limits. These radio devices are not intended for use by
consumers or the general population. Base station antennas must be positioned on towers or nonresidential buildings
that are generally unoccupied except while servicing the equipment therein.
Tables in the
RF Energy Exposure Guide
list the calculated lateral distances to be maintained between the general
public and an operational transmitter antenna for antenna types suitable in fixed and mobile applications.
Note
– RF exposure compliance at multiple transmitter sites must be addressed on a site-by-site basis. It is
the responsibility of the licensee to ensure compliance with maximum exposure limits
3.3
FIXED ANTENNA GUIDELINES
This section contains antenna information and additional notes regarding methods to limit RF exposure.
The licensee is required to comply with limits on antenna location, power, and effective antenna height per 47CFR
Subpart T §90.701 et. Seq., or Industry Canada SRSP-512 §6.3 as applicable. The section titled “
Transceiver-Radiated
Power Limits
,” below, provides additional information on how to comply with ERP limits.
Refer to the
RF Energy Exposure Guide
, which is packaged with each Base Station and Locomotive Transceiver and
available online or by request, for specific guidelines regarding placement and installation of fixed antennas.
Acceptable fixed-antenna types are listed in the Rated Power and Recommended Lateral Distance tables in the
RF
Energy Exposure Guide
.
Install antennas in accordance with the manufacturer’s instructions.
Disable the transmitter when installing or servicing its antenna or transmission line.
Maintain a safe distance from energized transmitting antennas. Refer to the table of safe distances for Base radios
in the
RF Energy Exposure Guide
.
Unauthorized antennas, equipment modifications, or attachments could invalidate any equipment warranty or
authority to transmit. Modification could damage the radio transceiver and may violate FCC or IC regulations.
Contact CalAmp before using other antennas.
3.4
RF INTERFERENCE TO RESIDENTIAL RECEIVERS
Notice to user:
This device complies with Part 15 of the FCC Rules. Operation is subject to the condition that this device
does not cause harmful interference.
Note:
this equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part
15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment to an outlet on a circuit different from that to which the receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
