APPENDIX ‘A’ – OCU CHANNEL CHANGING OPTION
Occasionally, a change of RF channel may be necessary due to radio interference or the fact
that the factory pre-programmed RF channel is already in use.
This is normally accomplished by reprogramming the TransKey (external programming).
However, some OCUs are equipped with a Channel Changing Option that allows the operator
to change the RF channel using the OCU keypad. If this option is available, an RF Frequency
Color Code Table similar to the example shown below will be supplied with your Remote
Control System.
Table A-1. Example RF Frequency Color Code Table
902 MHz LED
Channel Frequency 1 2 3 4
0 902.000 - - red -
1 902.100 - - - red
2 902.200 - - - green
3 902.300 - - - orange
NOTES: Regardless of the OCU model (6, 8, 10 or 12 buttons), in addition to the
‘ON’ and ‘STOP’ buttons, only the top two rows of buttons are used to
change the RF channel.
The programming mode can be exited at any time by pressing the
STOP button. In this case the previously stored RF channel will remain
in effect.
A.1 ACTIVATING THE PROGRAMMING MODE.
Refer to Figure A-1, overleaf
Step 1: Switch the OCU OFF and then keep the ‘ON’ button pressed for approximately 5-
seconds until the red ‘STATUS’ LED switches from permanently red to fast blinking red.
Step 2
: Within 3 seconds press the ‘UP’ and ‘DOWN’ buttons (in the top row), first and second
step, at the same time.
Step 3: The OCU is now in the programming mode. The ‘STATUS’ LED blinks orange and the
set RF channel is indicated via a color code (see example Table A-1, above) using the 4 LEDs.
