Troubleshooting
The DX does not react when you try to control it using the remote control terminal.
• Are the correct batteries loaded in the remote control terminal?
Check the voltage and polarity of the batteries.
• Are the batteries flat?
Replace the batteries with new ones.
• Does the ID number of the remote control terminal match the remote
controller ID of the DX that you are trying to control?
Check the remote controller ID on the DX, and set the ID number of the remote control
terminal to the same value.
• Is the remote control terminal in ID number setup mode (condition in
which the ID key is pressed once)?
Wait 8 seconds without pressing any keys to exit from ID number setup mode.
• Is the remote control terminal too far away from the DX?
Get closer to the DX. Control from as close to the front of the DX as possible.
• Is a strong light hitting the light-receiving section of the DX?
Take measures to prevent strong light from hitting the light-receiving section of the DX.
• Is there a magnetic field source such as a transceiver nearby?
Move the magnetic field source away from the DX.
• Is the infrared output section of the remote control terminal or the light-
receiving section on the DX dirty?
Clean them.
• Is the DX in a condition that allows the relevant key operation?
Check the condition of the DX, and start from an operation that is possible.
