Improving Receiver Control
Changing the UHF Frequency Using the A/B Switch
Your remote control has a switch to change the UHF frequency that your remote control uses. The
switch comes preset to the A position, but you can change the setting to the B position to lessen
the likelihood of another UHF remote interfering with yours.
1. Remove the battery cover from the remote control.
2. Use a small screw driver or a paper clip to carefully change the setting.
3. Put the battery cover back on the remote control.
4. Use the SYS INFO button on the front panel to open the System Information
screen.
5. Press RECORD on the remote control.
6. Make sure the System Information screen shows the correct band information:
• Switch position A - IR/UHF Pro Band A
• Switch Position B - IR/UHF Pro Band B
Installing a UHF Attenuator
Unwanted UHF signals may interfere with signals from the remote control to the receiver. To
prevent such interference, you can install a 10 dB attenuator (available from many consumer
electronics parts stores). Adding this attenuator will help keep out stray UHF signals, but it also cut
down how far away you can use the remote control.
1. Remove the remote control antenna from the R
