UPDAT E
Put the transmitter in UPDATE 
mode by simultaneously holding 
down the BACK and UP arrow 
buttons on the transmitter control 
panel while powering it up.
Step 6:
Using a microUSB cable, connect the transmitter to 
your PC.
Remove the lower housing of the transmitter by un-
screwing it from the housing attached to the capsule 
and pulling it straight off the body of the transmitter to 
expose the circuitry. Spring-loaded ball detents provide 
a “stop” with only the control panel exposed. Continue 
to pull the lower housing farther to remove it. Simply 
push the lower housing back onto the transmitter body 
to re-install it.
