Your ICR Transmitter comes from the factory with the maximum number of stations set to 9. This means that when you use the UP or DOWN buttons to change the station, you may change it to any number between 1 and 9. However, if you have controllers with more than 9 stations, you will want to increase the stations' maximum number.
The ICR is designed to operate with two groups of Hunter controllers:
To change the Maximum Number of Stations:
If the unit is OFF (no display), power the Transmitter up by pressing any of the buttons for at least 1 second then releasing the button. The Transmitter will illuminate the active station.
Press the MODE button until the word MAX STATION appears on the display. The maximum number of stations will be blinking at this point.
Use the UP or DOWN button to increase or decrease the maximum number of stations. Then do not touch any of the buttons for 5 seconds and the display will stop blinking and return back to the active station.
