Licensing 
To be operated legally, radio equipment requires two types of licensing - a 
manufacturer’s certification that the manufacturer obtains and a users license 
that the user must obtain. 
 
In most cases, the user of the TS4000 is required to obtain an operating license.  
This is the case for most frequency ranges in most areas of the world.  Licensing 
is done so that the government can coordinate radio users in order to minimize 
interference.  There are a handful of unlicensed frequency in the VHF band that 
are available for use in the United States (see Unlicensed Operation below). 
 
It is the user’s responsibility to obtain the necessary licenses prior to 
transmitting over the air with the TS4000.
  The user is also responsible for 
proper setup, operation, and maintenance of the TS4000 so that it complies with 
the limits specified by the license. 
 
Changes or modifications not expressly approved by Teledesign Systems 
Inc. could void the user’s authority to operate this equipment. 
 
Shielded cable must be used with this equipment in order to ensure that it meets 
the emissions limits for which it was designed.  It is the responsibility of the user 
to obtain and use good quality shielded interface cables with this device.  
Shielded interface cables are available from most retail and commercial suppliers 
of interface cables designed to work with personal computer peripherals. 
 
The TS4000 is licensed under the FCC (Federal Communications Commission) 
Part 90 rules.  The FCC regulates the operation and licensing of radio equipment 
in the US.  To obtain a license to operate radio equipment a user must fill out the 
appropriate FCC forms and pay an application fee.   
 
Many FCC licenses also require that the user obtain frequency coordination from 
the appropriate organization. The coordination organizations handle the up front 
work of qualifying applications and allocating channels.  The appropriate 
coordination organization depends on the type of license (voice, data, paging, 
etc.), type of user (business, government, etc.) and the frequencies 
 
To help with the licensing process, there are companies who, for a fee, will fill out 
and file the paperwork necessary to obtain a license.
