What is "Press Power Protect"?

After I play a few minutes of music (either CD or audio cassette), the music disappears, and the instruction "press power protect" appears repeatedly on the screen. I tried the Power Save button, but that didn't work. What do I do?

Hi Lois,
Stereo sytems have a protection circuit that alerts you by displaying "protect" when there is a electrical short circuit detected in the system, the most common short happens in a speaker, try disconnectig the speaker wires of both speakers(all speakers) at the back of the system, then play the CD or cassette player(although you will not hear anything with the speakers disconnected) and see if the unit goes into "protect" mode if the problem is still present then you have an internal short circuit and the system will need to be sent in for service or replaced(depending on age,repair costs). I would not recommend investing more than $80 into repairs. Now, if the unit does not go into "protect mode" then one of the speakers or speaker wires is shorted,be sure you check the conndition of the speaker wires before you replace the speakers, then you can replace the speakers(in a pair) and you should be back up and listening! Good luck and Merry Christmas !

Testimonial: "I appreciate the response! Since I am listening over a headset, I guess the short circuit is internal. --Lois"

Getting my aiwa to play cds or cassettes. Bought second hand no instructions .lights up won't play can I get instructions on how to get sound?

You don't state the model, so we are running blind here. It should be fairly obvious. For the CD press the CD button. Then press the door button and put the CD on the tray. Then press play or the door button again. If the CD player works it should play the music. Same with the cassette. Drop the cassette into the holder, push it back in place then press play.

Cassette mate

The product arrived with an instruction manual. I followed the instructions, installed the included software, and then was unable to get the product to work as my PC (Windows 7) did not seem to recognize the device. I tried several USB ports to no avail. I emailed the seller and promptly received an email with different instructions. Although the software version on the installation CD was different from that referenced in the instructions, I was able to install and finally got the device to work as needed. The problem is that there are two programs on the installation CD and one (cassettemate) appears not to function, while the other (audacity) is what is needed. This is not indicated in the instructions that come with the device.Close cassette mate window and open audacity press play in the cassette player and press recording button in audacity program.

How can I record a music cassette to a music disc on my Magnavox DVD recorder/ VHS --Model # ZV427MG9

You can't burn a CD-A with the ZV427MG9. The unit will not burn to a CD to play in a CD player.

You may be able to record the audio to a DVD with no video source. Connect your cassette player to the Line In audio ports (L/R) at either the back or front of the unit. Depending on your cassette player, you may need a 3.5 mm M to RCA F/F adapter to connect the RCA audio cable to the cassette player's headphone jack. Do not connect a cable to the video input of the composite input unless you have a video on a camera or something to play back. This means that the recorded video may say "No Signal" or will be black or static. (Note: this may not work with this signal issue.)

Set the unit to record to DVD on L1 or L2, as needed, by pressing Source on your remote. Advance the cassette to where you want to record. Press Rec on the DVD unit and then press Play on your cassette player. If you want to identify tracks, Stop the recording and play back and then press Rec and Play again. You are at risk of having issues with the volume during the recording. Clipping of overly-loud sounds and distortion is possible.

When done, finalize the disc, if desired, to play the disc on other DVD players.

If you want to make an audio CD, you would be better off using a computer and connecting the cassette player to the Line In jack of the computer. You do have to make some adjustments to avoid recording the default Microphone input. Use a program like Audacity or any other audio editing program. Record the signal and divide it into tracks, if needed. Now you can filter out any distortion as well. Then save as a WAV file. Use a different program to burn the WAV files to a CD-A. (This must be burned as a mastered disc; my attempts that worked on an older CD player failed if there were gaps between the tracks. Lots of programs will do this; Roxio Creator is one option.)

The manual for the ZV427MG9 is available here: http://download.p4c.philips.com/files/z/zv427mg9_f7/zv427mg9_f7_dfu_aen.pdf .

I hope this helps.

My Aiwa cx-nma545 keeps turning off.

Your system is in 'Eco' mode. If you are in this mode, and go 10 minutes without playing a CD or cassette, it will automatically turn itself off.

Here's how you get out of 'Eco' mode:

1) Go to the jog wheel assembly
2) Press 'Eco'
3) Press 'Enter'
4) The display will show "Eco Mode On"
5) Immediately turn the jog wheel, to turn the status from 'On' to 'Off'

Lost the manual, can't get hooked up

You need to use an audio CDr, data or computer CDr's will not work in this machine. I don't know this specific machine, but usually you select the input, then 'rec type' eg manual,1 track or 1 disc,then press record to get into record pause,start your source,then press play on the unit to start recording. To finalize, you press finalize then either the play or rec button to start the finalize process.
