Question about Dictaphone 3750 Desktop Cassette Transcriber / Recorder

Machine will not turn on and voice quality on tapes is not good

Hi, I bought this unit used online and seemed to work fine for a while but have noticed intermittent poor voice quality on tapes, like a wobbly sounding voice and sometimes muffled sounding. I have cleaned the heads with a alcohol swab and this did not improve the problems. I have been told that the door may be adjusted, so how is this done? Also yesterday when I went to turn it on it would not turn on? What could this problem be?

The door cannot be adjusted, but the head alignment can be. If you open the cassette door, you should be able to remove the door cover. Then install your tape and put into play. You will need a small phillips screwdriver (like you would use on eyeglasses). If you look down towards the front of the cassette compartment, there is a small cutout, and below that the adjustment screw. Turn it very little at a time, first clockwise. If it gets worse go the other way. If it gets better, keep turning slowly until the sound is the best quality. As far as not turning on, check where the power pack plugs into the back of the machine. I have seen where either the pin in the receptacle is broken, or if you remove the bottom cover, the solder points are broken loose and need to be resoldered. (I was a tech for them for 20 years).

20 year old Dictaphone Voice Processor Microcassette not working


Not sure if you're still having problems with this portable, but the first thing I would check is to make sure that you've put the batteries UNDER the battery clip in the battery compartment. Does the machine just make a 'beeping' noise when it tries to play, rew, or FF?

The tape might be getting old, replace it and see what happens.  If it is still acting up, It might be he is not recording properly or the recorder is bad.  Try talking directly into the mic and see if it is better.  If it is, he needs to talk louder or needs to hold it close.

Get the belts changed, and check a clutch inside the mech which drives the auto-stop mechanism.

It works in a way that it normally holds the auto-stop off if the spools are rotating, but when it wears, there is no srive through it to hold the auto-stop off, so the auto-stops stops, if you see what I mean.

Any good audio tech should be able to do this, if the machine otherwise works OK, it is worth doing because these are very nice and usually reliable machines.

For musical work though, the CP series are usually better, as they provide 3-heads and off-tape monitoring, with better quality and the facility to set tape bias to suit high-grade tapes.

Had same problem. Found online handbook for DS-4000 and page 37 pointed way.
Press menu button on the handset.Go to sub menu. Page 37 of online handbook suggests you can lock and unlock from this but I used the format icon on the submenu to reformat the card. Seems to be working fine now.
