| > | Interference on the channel selected. Reme- |
|
| dy: select different transmission channel. |
| > | Proximity to a microwave oven that is in |
|
| operation, causing interference. |
| > | Distance between transmitter and receiver |
|
| too great. |
|
|
|
Transmission of remote control | > | Faulty cable connection |
signals not working | > | No line of sight between IR remote control |
|
| and receiver, resp. between IR transmitter |
|
| and signal source. |
