UNIDEN DECT 1805 Power Adaptor

If it's the same as other Uniden DECT phones, then it's positive to the tip.

MrT.

This one has a power plug that is exactly like the telephone line plug (RJ...). The difference is that the two inner conductors are used for the phone line, while the outer ones are used on the power adaptor cable. It isn't your normal DC plug and socket. I can recall that it's a 9v dc adaptor, but I just can't recall the polarity. I guess I'll just pull the back off and take a look.

There are two voltages on the RJ-12 plug on my Uniden 1805, 8V and

Negative is to the right outside on the 8V power, looking at the connector connector side up and with the connector cable going away from you.

I can't seem to measure the 4.5V voltage on the pins on the left side, since my DVM probes are having trouble making contact on the dinky RJ-12 contacts. I eventually gave up.

I have a separate RJ-12 cable/connector for the phone line, and the power RJ-12 connector only has power on it.

Sorry for the incompleteness of the info, but I hope the incomplete info is at least some help.

Actually that is positive 8V to the outside. :) Sorry about that.

I still can't find the 4.5V anywhere.

Thanks Ross - I have a spare 7.5 and a 9 v adaptor so I'll give one a try. If it doesn't work - too bad.
