I have installed a jvc kds 611 in my car, when i remove key from ignition i lose the saved channels and the clock time and channels needs reset can u help me thanks

It's possible that the DVR's internal battery is losing charge, causing the clock to lose time. Typically, DVRs use a small lithium battery to power the clock and other internal functions. Over time, this battery can lose its charge or fail entirely, which can cause the clock to lose time or reset completely.
To replace the battery in your Channel Master DVR, you'll need to open up the device and locate the battery. Depending on the model of your DVR, the battery may be easily accessible or it may be hidden inside the device. You may want to refer to the user manual or contact Channel Master for specific instructions on how to replace the battery in your model.
Once you've located the battery, you can replace it with a new one of the same type. Lithium coin batteries are a common type used in electronics, so you should be able to find a suitable replacement at most electronics stores. After replacing the battery, you may need to reset the clock and other settings on your DVR.

To reset the clock on a JVC PC-110 boombox from 1994, follow these steps:

1. Press the Clock Set button, located on the top of the boombox, to enter clock setting mode.
2. Press and hold the Clock Set button until the hour digits on the display start flashing.
3. Use the Fast Forward and Rewind buttons to adjust the hour to the correct time.
4. Press the Clock Set button again to move to the minute digits. The minute digits will start flashing.
5. Use the Fast Forward and Rewind buttons to adjust the minute to the correct time.
6. Press the Clock Set button one final time to exit clock setting mode and save the new time.

Your JVC PC-110 boombox should now display the correct time.

If your asking about the radio channels and radio clock, there is a wire that is always hot that has to be connected to the radio's always alive wire. If it is not hooked to the wire that is always hot, (like hooked to an ignition wire) then it will not be hot and every time the ignition is turned off, you will lose the clock time and channels memory. If you have a test light, check the wires at the radio (with the key off) and see which one is hot. If none are hot, then you have a blown fuse or wire broken.

it look like you lose the ignition current at clock radio
check all fuses

There should be a yellow "accessories" wire that controls the memory to the radio. If it is not properly hooked up, the radio will reset every time you turn off the ignition.

NOTE: It might be a different color than yellow, but this is the most common

Hello there,
Check out this PDF from JVC's site:

It's for your KD-S14, and the settings chart is shown on Page 3 and does give a general shakedown of how to set the clock.

I hope that works for you.

Hello there,
Here's the PDF from JVC's site:

It's for your KD-S15, and the settings chart is shown on Page 3(left side) and does give a general shakedown of how to set the clock.

I hope that helps.

The radio was improperly installed; there are two 12V leads, one services the radio when on, the other, only the circuitry for the clock and presets.
Eventually, this shouldn't be needed if the manufacturers ever think about using a little bit of flash memory for the presets and a coin cell for the clock.

You didn't give any model number so researching the manual is impossible.
If you can find the model number, look for a user's (or installation) guide on line to find the wiring info.

Hi,
You'll find your answer here:

Just download the pdf instruction manual.

Do you also lose your clock and radio station presets?
