Troubleshooting
Solutions
•
There may be interference from automobiles,
trains, high-voltage lines, neon lights, or other
factors.
•
There may be interference between the antenna
cable and power cable. Try positioning them
further apart.
•
The unit may be receiving interference from other
devices. Transmission antennas of radio
broadcasting stations and transmission antennas of
amateur radios and cellular phones may also
cause interference.
•
Use the unit as far apart as possible from devices
that may cause possible interference.
Solution
Replace the batteries with two (2) new AA alkaline
batteries.
Make sure the remote control is aimed at your home
entertainment component and is not farther than
15 feet away.
Try all listed codes for the component brands being
set up. Make sure they can be operated with an
infrared remote control.
Follow instructions in "Changing Volume Lock."
Due to RCA design (1983–1987), only the original
remote control will operate these functions.
If original remote control required pressing ENTER to
change channels, press ENTER on the Remote control
after entering the channel number.
Try the "Search Method" again after clearing out the
component button as follows: Press and hold SETUP
until red light blinks twice, then release. Next enter
9 - 9 - 2. Then press and release the component
button to be cleared twice.
