    Thanks a lot for your great comment "fredy2",

    Here is the detail of problem happen on my Yamaha mixer AW4416:
    Firstly, On the LCD screen always shows warning message "LOW BATTERY", it makes me confusing when working with this mixer.
    Secondly, all customization preset cannot save to memory: when I turn off and turn on the mixer, these values were reset to default values (not expected values)

    I want to confirm the sympton happened in your mixer,
    If the sympton is similar, I can order this chip and repair this mixer by myself,

    Looking forward to receive your reply soon,

    Thanks again,

The "battery" MAY be a soldered in type.

Here is your service manual:

Scroll down on the web page to "Get Manual" and download the manual.

The battery is on page 153 in the manual at grid N-10... you are NOT going to like this... it is in a Dallas Semiconductor real time clock chip... You have to replace the chip. It is IC709 which is a DS12887 chip.

The physical location can be found on page 58 about half way down the "A" sectioning line on the right side of the page. It is a 24 pin chip... It MAY be in a socket, or maybe not... PRAY !

Wow... $11.12 each from

This info took me about 1 hour to dig out...searching for a battery was futile until I found the battery was related to the real time clock. If this isi soldered in, you need to have proper tools as the board is likely multilayer and takes care in solder removal... especially the new ROHS hi temp solders. You should take this to a board repair house if it is not socketed.

    Thanks a lot for your great comment "fredy2",
    Before replace IC709 in my mixer, I want to confirm the problem happened in your mixer is the same with my mixer first,

    Here is the detail problem happens on my mixer:
    On the bottom line of LCD always shows message "LOW BATTERY!!",
    Moreover, somtimes all customization preset values (in Automation Fader) cannot save after reboot mixer,

    If the problem is the same, I can order this chip and can repair this mixer by myself,
    Looking forward to receive your great comment/ solution soon,

    Thanks again,

    I do not have the mixer myself, however I am an electrical engineer and have used the Dallas Semiconductor chips with embedded battery before. The chips, upon power being applied, first go into a mode that allows the firmware of the device they are used in to sample a bit of data that signals if the battery is becoming low. This sampling is ONLY done when power is first applied each time. I have used and programmed a product myself using these devices. This is the only battery in the mixer unit and is the cause of the message you are getting. Make sure you get fresh device so battery life is near full. The devices drain from the time they are made. The expected life at normal tempeatures should be 5 to 10 years. At higher temps they drain faster. Replace the chip and the message will disappear !!! Now about the customization values... The real time clock chip has some storage and they may time tag it with the RTC which could cause the loss of the values. MANY of the devices that store customized values do so in flash memory and those memories can develop problems, especially if power sequences down incorrectely. Changing the flash memory, IF it has a problem is not DIY as it requires specialized tooling. Following the procedure for shutdown is important and completing it each time is crucial to maintaining the values. Replace the IC709 chip and see if that will cure all the symptoms... I know it will fix the battery problem UNLESS there are major problems which I doubt are there if you can use the unit at all. Feel free to contact me email when you get the part replaced... the source I gave you usually has parts delivered to anyplace in the USA within 5 working days. Use care in handling the product and if in socket, make sure all the leads go in straight. The chips usually have the leads SLIGHTLY bent out for retentionwhen used as solder in, so CAREFULLY make the leads parallel before putting into a socket.

    I'd ordered the similar chip (DS12C887+ instead of DS12887) and replace by myself,

    It worked like a champ,
    Great thanks for your quick support,

Yamaha dtxplorer!!!! I replaced the battery and still have a warning low battery notice on the screen. Anyone else had this problem?

If the new battery tests good on a voltmeter ( you'd be surprised how often they don't) I would suspect that the battery holder's contacts need to be cleaned.

Circuit boards

Due to the nature of the board connections and design; you need to use the exact replacement made for your model. Yamaha made the original and any other clone (if available) may not function properly. You could end up wasting your money. Either get the Yamaha replacement, or look for a used model in eBay or the internet. Other than that, use the $477 as a down payment on a new system.

I just bought 2 of the DSR 115 Yamaha speakers. One of them is NOW making a "light fluttering" sound from the woofer! Could this damage caused by my "Yamaha GQ 1031 b EQ"...

Don't mess with it and risk voiding your warranty. These are a servoed speaker and there is a problem with the feedback in it. Exercise your warranty immediately.

Is the red light indicator ment to stay on all the time when playing, or is this a warning light to let me know that the battery is low .Thanks and kind regards Neil

Simple test to try: Put in a brand new battery... If light goes out, then it is a low battery warning.

HOWEVER, it is likely a warning that battery is on so you don't forget to turn it off when done. Tried to find manual for it and could not. Your manual should tell about it.

Hi my name is Susanna and I own a Yamaha DTXtreme iis and whenever I turn the power on the screen shows this message: WARNING:DATA INITIALISING PLEASE PRESS ENTER. Then all my memory of the user programmes...

Probably the battery replacement was NOT done correctly or there is a problem with the battery voltage getting to the memory.
The original message was probably the result of the unit detecting the data was corrupted due to the backup battery not maintaining the memory.

The CORRECT Lithium cell for this unit is a CR2450

This is NOT a common available cell and LIKELY the person installed a readily available one which is not working.

Here is link to a supplier:

This cell is thicker than the commonly available cells and if the readily available was installed, it would not make contact. Open the unit and check the cell in the holder at BT1 on the board.

Here is service manual which has disassembly instructions.

Yamaha Motif 6 froze, tried re-booting screen is stuck on the initial page "Now Checking plug-in board..." Also unplugged the keyboard.

This is a long shot... If you have an add-in option board it may have become dislodged from the socket. If you move your keyboard this may be what happened. In any case it needs to be opened and look for loose cables, board, OR if you have a hard drive, the drive may have failed. The software in these units isn't smart enough to give the user any details of the failure/hangup.

You can replace the battery yourself in about 20 minutes. It is not soldered. You will need a replacement battery, which is a CR2032 watch battery, a small Philips screwdriver, and needle or thin-nosed pliers.
1. Remove all cables from the dtxplorer unit, and remove it from the drum kit rack.
2. Remove all 6 screws from the bottom side (i.e. opposite the face)
3. Remove the 3 lowest screws from the rear (jack-filled) side, including the one which holds in the little plastic power cord hook, then lift off the bottom and set aside.
4. You will see the bottom circuit board, covering the top board. Carefully pull off the spade connectors from the power switch, using pliers or patient wiggling, they are on fairly tight but will come loose. Note which one is which for proper reattachment.
5. Near the center of the board is a little white plastic post end sticking up, through a hole, from the inside (top) board, with small tabs. This loosely attaches the two boards. Using small pliers, squeeze the tabs on the post end, and pull up on the board and it will separate from the inside (top) board. Carefully move the board toward the front of the unit to free the jacks from the holes in the case, and then you can easily fold the board toward the front, like opening a book. (Don't try and remove the large wire sets attaching the two boards)
6. You will see the button-like battery. Just push it toward the spring clips at one side and lift it out. Replace it with the new battery, + side out.
7. Just reverse the steps to reassemble, hook it up and you're ready to go. Easier to do than this makes it seem. Greg
