Question about Sony ICD-BP150 Digital Voice Recorder

Can I plug it into AC power?

I'm burning through batteries, even rechargeables, way too rapidly. Is there any way to plug this darn thing in? Sony is silent on the matter. It has a plug for "Plug In Power", but that apparently refers to the type of microphone, and not an AC Adapter. Thanks, Dave

Re: Can I plug it into AC power?

If you get hold of an AC adaptor that gives the same voltage as the batteries (total if more than one), you can then connect it to the first and last battery terminals, (correct polarity). If you want to make it more "professional" or convenient then a pieces of wooden dowel the same size as the batteries, with a metal nail for the positive end, thumbtack for the negative end with the wires from the adaptor wound round/soldered to the end terminals works well and can be easily taken out and swapped for batteries when you need to. Hope this helps, please ask again if you need more clarification.

Won't turn off

If all things considered that your settings are correct, you may have to open the unit, unplug the battery, then plug back in again.

How do I stop the clock needing to be reset each time I power on on my PCM-M10?

from: The Taperssection Forum
"Hi all,

maybe I can offer an explanation why some people have the RTC problem and others have not. After leaving my M10 on the shelf for about two months without switching it on (batteries were still fully charged!), I had to set the clock.
So I wondered what is going on. I pulled out the schematic of the M10s big brother, the D50.
The power supply section is rather complicated with lots of MOSFET switches and regulators, even one for the RTC battery. Checking the component values, I guesstimate that it takes about 30 to 40 hours to recharge an empty RTC battery - the state of the battery is in when you are asked to set time and date. If fully charged, you can expect 2000-3000 hours of RTC operation.
It seems to me that the D50 (and probably the M10) switch off completely when battery powered - not even the RTC battery is recharged!

So it depends on your use profile whether you have the dreaded "set date and time" problem or not. Regular use (best every day) keeps the RTC battery charged. in the future, I will let it go into sleep mode, and not switch it off. Another solution is to plug in the power supply before storage and let the M10 run for two days to top off the RTC battery, this should be sufficient for two months.

BTW if someone could send me a schematic of the M10, I could replace my educated guess with fact.

Hello, My M-Audio microtrack 24/96 battery runs out so fast. What do I do? Is it time to change it? Is getting a new battery expensive? Do I not charge it long enough? I let it charge for at least 4 hours...

Similar problem to mine, and until I get my question answered, I can only propose a temporary solution.

Get a USB cable that fits the bottom small USB socket on your M-Audio Microtrack, but with a standard USB plug on the other end. Such a cable should have come with your Microtrack to begin with.

Replacement cables can be found at Best Buy, Radio Shack or most electronics stores or department stores. If the original cable is broken, please save it for reference to make sure you are getting the exact same type connectors when getting your replacement.

As I learned the hard way, not all small USB connectors are the same size, but APPEAR the same.

So, what are you connecting on the standard USB end?

A battery.

That's right, a rechargeable battery that features a power-only 5 volt USB receptacle. This will function as your A/C power adaptor does, only on the go.

The external rechargeable battery I use is a Black and Decker "Power to Go" unit that measures approx. 5 1/2"L X 3"W X 1" D.
It has both a low-draw two-prong AC (yes, it has an inverter and I never use it) and the desired 5V USB receptacle. You may find a better solution WITHOUT that A/C inverter. Just ask around for a rechargeable NmHh (better than NiCad) battery with a standard USB receptacle.

If the Microtrack's power is off when it is connected to the 5V power source (be it A/C power adaptor OR my proposed external battery), it will go into charge mode. With a fair amount of charge, remove the external power, and it boots up into operation. Then, re-connect the external power and your Microtrack is running and recording for a considerable longer time, depending on the charge and condition of your external battery.

Now, if one observes the LCD screen while running off of external power, the upper right corner box indicating the internal battery's charge shows "CHG" instead of the black square (Full charge) or half of the box in the form of a triagle (half charge) or any variation thereof as normaly indicated.

Someone might say, "But I don't want to have to carry around all this extra stuff! I want my old battery life back!"

Well, that's precisely how I feel as well.

But until you get your original lithium ion battery replaced (and at what cost for parts and labor?), you have to ask yourself if being an original condition purist is serving your situation well, or if this proposed add-on can get you by in the meantime.

Take care.

Ask your dealer, the one you bought it from. They may suggest an easy fix or guide you best on how to get it repaired, or at the very least suggest a place near you to have it repaired. If your dealer doesn't know, ask any Zoom dealer for repair info. Meanwhile, I assume you've checked your battery compartment to make sure the terminal connections are not loose (and of course that you've tried new batteries - :) ). Also, check Menu>Battery to see if alkaline or nickel batteries is checked. Finally, try removing your SD card and re-inserting, (even re-formatting the card, perhaps, but trying merely re-inserting first). But make sure any songs/info on the card are backed up first, because you will lose info if re-formatting the card. (For that matter, you could try a new card.)

i have this issue more or less whenever i change the batteries, i use rechargeables and i think that may be part of the issue. anyway... as silly as it sounds i just keep taking the batteries in and out and messing around swapping them with AAAs from other gadgets that i have and eventually the device works again and all my recordings are still there.

it just happened again this evening, when i put 2 newly charged batteries back into it after them being out for about 24hours.
i messed around with combinations of flat rechargeable and alkaline and charged batteries and eventually it worked again, when i used a charged and an almost flat rechargable combo. i mustve put the batteries in and out about a hundred times but it does the trick in the end.

oh, i have a ICD P520 by the way, but i think theyre all the same. and i have to agree with that other pointless post, what a load of ****. you shouldnt pay this much money for something that doesnt work properly.

If you are getting a low battery light (that may be the cause of you problem), you should check that the AC outlet settings are right. If the settings are correct, you should take out the AC adapter and try it with batteries (do not forget to disconect the AC from the power and from the recorder!!!). hope this will help. Daniel
