I cannot turn the unit on.
- Check whether the HOLD switch of the man body is in the HOLD position.
- Check whether the battery is sufficiently charged.
- Press and hold down Reset Hole for 3 seconds and then press the MENU button.
The AC adapter does not work.
- Check that the AC adapter is properly connected to the DC jack of the unit.
The remote control does not work.
- Check whether the HOLD switch of the remote control is in the HOLD position.
- Check whether the remote control is properly connected to the unit.
I hear noise when listening to the radio and I cannot locate channels.
- Try to move the product, the remote control and the earphones around until a better signal is
received.
- Turn off appliances near the product. If this works, place the unit far from appliances when
using the unit.
The TV screen ‘wobbles’or displays abnormally.
- Which TV do you use?
- If Menu → Display → TV Out is configured to NTSC, the signal for NTSC TV is output and
if it is configured to PAL, the signal for PAL TV is output. Check if the configuration is
appropriate to your TV.
The Video or image file is displayed too small on the screen.
- This may happen when a video or image file is created in small screen resolution.
The video playback seems abnormal.
- The loading time for video playback may be longer than that of an MP3 or WMA file.
This is normal because more data has to be loaded to play a video file than for an
MP3 or WMA file.
- When playing unsupported video files, you can only hear sound or you can view the movie file
without sound. Alternatively you may experience discontinuous screen or sound play.
In this case, check your product specifications.
- The product only supports the MP3 audio format for video files. It does not support AC3 and DTS.
- A video file whose screen resolution is higher than the resolution specified by the product specifi
cations may not be played.
