How do I change the battery in a digimatic model # cd-6

This may be a little late but the answer is "there is no battery". The whole face except for the display is a solar cell. Use it in plenty of light and it will stay on. If you block the light while using it and the internal storage cap has a small charge on it the display will turn off.

You may use Xbox 360 Universal Media Remote. It supports DGM and Digimate TV's officially. You can buy it in GameStop stores from 10$.
Codes for DGM - 1435, 1890, 2020, 1581, 2059, 2165, 2282, 2283, 2062, 3045.
For Digimate - 0890, 2020, 1581.

I know what this is, when you changed your battery you reset your in dash cd player. Shuting off the security code. you need to take it to a shop or at the worst your local Dealership and they can reset the security code on your radio and it should work proper again. This is an anti theft device that disables the deck if it is removed from the dash Or from power. Hope that helps.

Hold the origin button for greater than 1 second. You may need to use a point tool to push the button all the way down.

Requires a code

Remove the radio from the dashboard and post the MODEL NUMBER and SERIAL NUMBER found on a label on the radio casing

For any manual contact Mitutoyo nearest office , they are professional and will help you.

There should be a battery cover on the back of the case that will have a small release catch on it that will open the compartment up. Mine has 2 batteries in it. Hope this helps you.

The CD changer probably failed to establish it's link to the head unit when you put the new battery in.

Since you've already tried the clear button, I'd suggest unplugging the IP-BUS cable (black cable) from the back of the changer, wait a minute (literally, 60 seconds) and plug it back in.

Did you change the battery ? If so try disonnecting and reconnecting the CD changer.

i'm not sure what kind it uses but try Batteries plus. they have zillions of batteries. http://www.batteriesplus.com/
