Now, carefully press the module into place (on to the receiving Velcro). You can wiggle the module

to make sure it is seated properly and will not detach during normal use.
See Figure 16 for details.

Note:
If you switch back to a stock RF module, remember to re-install the antenna or damage may result
to the transmitter! You do not need to remove the Velcro to re-install the stock RF module.
Turning on the power to your Profi radio now should cause the LED on the Graupner | iFS-System
RF module to light up briefly orange, and then begin flashing red.
If this does not occur, turn off the radio and make sure that you do not have the connector installed
backwards! No damage will be done if you did, just reverse it and try powering on again. If the LED
does not light up at all, contact our Service Dept. for more information.
All programming must be done with the back of the transmitter off due to the location of the push
button switch and LED on the Graupner | iFS-System RF module
Useful hints: The GRAUPNER iFS-PROFI-RF modules are default configured for the use in Eu-
rope. So no changes to the settings should be necessary in most cases.
Please note that care must be taken when removing the antenna for range testing. The ball is not
held firmly in place and can rotate, destroying the cable connector!
