AIWA MINI DISC RECORDER AM-F80

does it have a wall plug ?

Fixya doesn't, but you can try Googling (Aiwa)(SX-WNA909)(manual) without parens.

The Aiwa batteries are hard to come by. I got rid of a lovely Aiwa pootable becasue the only battery available was $150. Many of the older models use rare batteries which are just not made anymore. You may find a NOS one for a high price on ebay or a used one with some life in it.

This is a sadsituation because they were great machines...

What problem are you expecting the tech guys at FixYa to fix?

Not clear what your problem is.

My guess is that you are trying to record on a pre-recorded minidisc. You cannot.

Buy some blank discs. You can record and re-record to your heart's content.

That seems quite odd and makes no sense. Perhaps you should wander through the menu options. Is the cable or headphones OK?

Plug in the appropriate power supply or charge the batteries through an external battery charger.

There are discs all over eBay. Don't pay more than $2.25 each.

memorex and kyphermedia WON'T work in this recorder FYI Don't know what brand will

CHANGE RCA JACKS ,,COULD BE A BAD ONE,, ALSO ,,TRY BLOWING IT OUT
