Setting THH06 and TBP06 Transmitters to XD-V30 Compatibility Mode

The XD-V35 system ships set to the new dual frequency RF2 mode. To use an XD-V35 version 

transmitter with an earlier generation XD-V30 receiver (RF1 mode), you must change the transmitter 

from RF2 mode to RF1 mode.  The method differs slightly between the handheld and beltpack.

THH06  Handheld Transmitter

• Turn the transmitter off. 
• Press and hold the channel SELECT button.
• While holding the SELECT button, press and hold the power ON button.  
• The blue LED over channel 1 will flash three times to indicate that the transmitter is in the 

RF1 mode. 

• To revert to the RF2 mode, repeat the above steps; the blue LED over channel 2 will flash 

three times when the transmitter is in this mode.

TBP06  Beltpack Transmitter

• With transmitter off, set the Channel Select slide switch to channel 6.
• Turn on the transmitter.
• Wait for the blue LED to flash followed by a green LED flash.
• Immediately slide the Channel Select switch completely left to channel 1.
• Quickly slide the Channel Select switch completely right to channel 6.
• This process must be completed within three seconds of turning on the transmitter.
• The blue LED will flash once to indicate that the transmitter is now in the RF1 transmission 

mode. To revert to RF2 transmission mode, repeat the above steps; the blue LED will flash 

twice when the transmitter is in this mode.
