I need to know the POLARITY of the AC adaptor to provide the correct setting using a universal adapter.

there is no polarity in ac current as ac means alternating current and that means alternating between positive to negative back to positive back to negative and so on
only dc ( direct current ) and the center pin of the plug is designated as the positive pole has polarity, the outer case being the negative
OR Are you asking the voltage of the ac adapter and the voltage of the dc output side of the adapter

What voltage and polarity do the ACS-5 speakers require?

Computers always use DC voltage. Computer speakers receive DC voltage from the computer.
DC voltage has a Positive and Negative polarity.

In the power jack of the speaker, the Center pin is the Positive connection. The outer shell is the Negative connection.

Center hole of the DC adapter plug - Positive.
Outer shell of the DC adapter plug - Negative

Voltage 5 Volts DC.

I have a Casiotone MT70 made in 1984. How do I check the polarity as I need to get an AC Adaptor and don't want to damage the keyboard?

Here is how you might check the polarity of a 7.5 volt DC replacement adapter:

Put the 5 batteries into the unit and verify operation. NOW using a DC voltmeter measure the voltage from battery negative and meter negative connected and meter positive to the pin on the power jack. IF you see 7.5 volts positive, then the pin is the positive lead for the adapter.

If you see zero, then continue testing.

With the 5 batteries inserted, connect the positive meter lead to the positive of the stack of batteries. Now touch the negative meter lead to the pin.
If there is 7.5 volts there, then the pin is the negative lead for the adapter.

READ THESE INSTRUCTIONS CAREFULLY.

USUALLY the jack has a contact that disconnects the batteery when the plug with sleeve is inserted.. We are testing the jack without inserting a plug here so the plug should HAVE THE BATTERY VOLTAGE with correct polarity on the pin.

USB Cable Vivitar for ViviCam 5385

Most probably find a Vivitar Vivicam 5385 manual here. Just send them a search request. Search service is not for free, but worthy.

AC adapter for ViviCam 3765.

The polarity is correct, but 400mA is not enough. One commercial supply I saw was rated at 2.5A. I even suspect 3v isn't enough as I have tried an external battery pack with D-Cells in it and after a few flash shots it wants new batteries. The camera itself seems to be over-sensitive to "low" voltage and complains about new or freshly charged batteries (see other posts).

There is a problem with these cameras in this battery voltage area. I have asked Vivitar what external voltage to use, but no reply. Good luck! I am sufficiently fed up with this camera that I may try 4.5v external supply and if it blows up, good riddance!

Mains powersupply

If you are thinking of runnig it from the mains supply then you will need a 3v units - a common universal unit from will do it the camera will have a diode thats protects the polarity and a universal power supply with have reversible connectors
