Environmental Information
The manufacture of this equipment has required the extraction and use of natural resources.
Improper disposal may contaminate the environment and present a health risk due to hazardous
substances contained within. To avoid dissemination of these substances into our environment,
and to limit the demand on natural resources, we encourage you to use the appropriate recycling
systems for disposal. These systems will reuse or recycle most of the materials found in this
equipment in a sound way. Please contact GE MDS or your supplier for more information on the
proper disposal of this equipment.
ESD Notice
To prevent malfunction or damage to this product, which may be caused by Electrostatic
Discharge (ESD), the radio should be properly grounded at the time of installation. In addition, the
installer or maintainer should follow proper ESD precautions, such as touching a bare metal
object to dissipate body charge, prior to touching components or connecting/disconnecting
cables.
Antenna Installation Warnings
1. A suitable lightning arrestor should be used when indicated by applicable standards or
codes.
2. All antenna installation and servicing are to be performed by qualified technical personnel
only. When servicing the antenna, or working at distances closer than those listed below,
ensure the transmitter has been disabled.
3. Depending upon the application and the gain of the antenna, the total composite power
could exceed 90 watts EIRP. For fixed/mobile configuration, the distances in the table
below must be followed.
FCC Compliance Notice
This device is offered as a licensed transmitter per FCC Parts 80, 90 and 95. It is approved for
use under the following conditions: Changes or modifications not expressly approved by GE
MDS, LLC will void the user's authority to operate the equipment.
The TD220MAX is approved in the following FCC rule parts:
•
FCC part 80, approved for operation from 216-220MHz, 28 watts
•
FCC part 90, approved for operation from 217-220MHz, 1.66 watts
•
FCC part 90, approved for operation from 220-222MHz, 27.5 watts
•
FCC part 95F, approved for operation from 218-219MHz, 20 watts
Please refer to your FCC spectrum license to ensure you are in compliance with the appropriate
radiated power levels.
For FCC Part 95, the Effective Radiated Power (ERP) must be less than or equal to 4 Watts for
mobile use and 20 Watts for fixed use. This can be accomplished by adjusting the output power
of the radio and selecting an antenna with appropriate gain. Consult the following table for
assistance in setting the output power and selecting an antenna to maintain compliance. The
table provides examples, however other combinations can be used.
