available on the Ion 350RT.
For more complete instructions, refer to the 
Transmitr manual at bontrager.com
All pairings must be done in a single session. 
Before starting, place the remote and all lights 
within a small area.
NOTE: Move 15 feet from other Transmitr / ANT+ 
compatible lights to prevent accidental pairing. 
If a light is accidentally paired, start the pairing 
process over.

(within 15cm / 6in).

2.   Quick-press the power button on the light to 

turn it on, then quick-press to turn it off again. 
NOTE: After completing this step, do not 
press the power button on the light again until 
pairing is complete.

3.   Press-and-hold the center button on the 

Transmitr Remote for at least 8 seconds. 
When the corner buttons flash, release the 
center button.

4.   While the remote searches for a light, its 

center button flashes red. When the Transmitr 
Remote finds a light, the center button on the 
remote will change from red to green, and the 
found light will flash.

5.   While the found light is still flashing, quick-

press the button on the Transmitr Remote 
to which you would like to pair the light. The 
selected button will glow, and the found 
(paired) light will stop flashing and turn off.  
NOTE: After the pairing, the center button on 
the remote will flash red until the Transmitr 
Remote finds another available light.

6.   Repeat Step 4 and Step 5 for each additional 

light to be paired.  
NOTE: After pairing is finished, pairing any 
additional lights will require that you repeat 
the entire pairing procedure.
