Deleting All Learned Functions
To delete all learned functions as once, use the procedure below.
1. Press and hold the CLEAR button (the current component button lights). Then press
and hold the ON/OFF button (component button light turns off for 3 seconds, flashes,
turns on and off) while continuing to hold the CLEAR button.
2. Release both buttons (current component button turns on).
3. Press any component button to delete all learned functions in all modes. The RCU
automatically exits this clearing mode.
Note: Pressing the CLEAR button while in this mode will not delete the learning functions,
but it will exit this delete mode.

Troubleshooting
If the IR functions on your RCU don’t work properly...
• Something might be between the RCU and the remote sensor on the component. Make
sure there is a clear path.
• The RCU may not be aimed directly at the component (TV or VCR) that you’re trying to
operate.
• The RCU might not be in the correct mode for operating that component. Try pressing
the corresponding mode switch (TV, AUX, etc.) then try operating the component with
the RCU.
• The batteries in the RCU might be weak, dead, or installed incorrectly. If batteries are
weak, the backlighting will be weak on the device mode buttons. In this case, put new
batteries in the remote. (Note: if you remove the batteries, you may have to reprogram
the remote to operate other components.)
• When using the Learning feature, do the learning process in low light areas to prevent
natural light and fluorescent light from interfering with the infrared signals.
If the RF or gyro functions on your RCU don’t work properly...
• If the RCU does not appear to be working at all, it may not be connected or
synchronized with the USB RF transceiver. Repeat the Setting Up and Synchronizing
the Remote and the Transceiver procedure above.
• If, when using the RCU as an in-air cursor control, the cursor is visible on the screen,
but shows no movement, the gyro may not be activated. See the Gyro Operation
section above to activate the gyro and in-air cursor control.
• If the cursor movement is choppy or erratic, there may be radio interference. Move the
USB transceiver away from other electronic devices such as monitor speaker or radios.
• The batteries in the RCU might be weak, dead, or installed incorrectly. If batteries are
weak, the backlighting will be weak on the device mode buttons. In this case, put new
batteries in the remote. (Note: if you remove the batteries, you may have to reprogram
the remote to operate other components.)
To delete a learned button function, use the procedure below.
1. Press and hold the component mode button (the component button lights). Then press
and hold the CLEAR button for 3 seconds. Hold both buttons depressed until the
component mode button flashes.
2. Release both buttons. The component mode button turns on indicating that the RCU is
now in the Clear Learned Function mode for that component.
3. Press and release the button where learning is to be cleared. The component mode
button blinks off then back on indicating that the function was cleared successfully.
4. Repeat Steps 1 through 3 until all the buttons’ learned functions have been cleared.
Note: If an invalid button is pressed, the component mode button flashes 4 times, the
selected component button stays on, and the RCU remains in Clear Learned Function
mode. Repeat Step 3 to continue the clearing process.
5. Press the CLEAR button to return the RCU to normal operation.
