MAINTENANCE 

 

No routine maintenance is necessary, other than to remove accumulated dust. If the equipment is 
accidentally impacted or dropped operation should be fully checked and an internal inspection 
made for loose or broken parts.  

 

SERVICING AND REPAIR 

 

Should the M15-25 require warranty servicing, return it to Mentor Radio with a description of the 
problem. For out-of-warranty servicing, returning it to Mentor Radio is also recommended, but if 
local servicing is preferred, service manuals can be obtained.  Service should only be attempted by 
technicians experienced with this type of equipment and who have available the appropriate test 
equipment.  

 

LICENSING 

 

In the United States, all transmitters must be licensed by the Federal Communications Commission 
(FCC). Application is filed on FCC form 406 for base stations. The M15-25 contains two different 
equipments which must be listed on the application. Do not list the M15-25; instead list the M15 
transceiver (FCC identification no. QQTM15) and the PA25 power amplifier (FCC identification no. 
QQTPA25).  
 
With each new M15, Mentor Radio, LLC. include instructions on how to complete form 406 online at 
the FCC Internet web site (Dwg. 1100958).  If the M15-25 is to be used on a channel in the 
frequency range 128 to 132 Mhz (the “enroute” channels), the license application is handled 
differently. Assignment of specific frequencies and the completion of form 406 is done by 
Aeronautical Radio Incorporated (ARINC), a private organization which contracts to the FCC to 
manage this part of the spectrum. Refer to Mentor Radio, LLC. dwg. 1101472, enclosed with new 
units containing an enroute frequency.
