Okay,

I ran some tests.

I tried a different SD card and noticed the problem was still there and also noticed it had something to do with the position of the LCD screen. While rotating the screen (during the rotation) you ALWAYS hear that annoying beep.

In some positions the beep is gone, for instance when the screen is rotated away from the operator. Bottom line: it is very like to be a problem in the screen cable or hinge.

Hi,

I just bought an Aiptec Z700 in France. The loaded firmware is 2802.

I have the same annoying sound problem (high pitch) whatever the screen position.

I wanted to upgrade to firmware 2900 (available on the aiptek site) before contacting Aiptek, but i can't get write access to the internal memory or SD card (with direct USB link Z700/computer).

I tried to mount manually the SD card under a Linux system with read/write permissions but the system tells that the device is write protected, so it can be mounted only in read only mode.

I haven't at this time any external card reader to copy the updated firmware.

I wanted to know if the replacement of the others defective z700 had solved the sound problem and if someone knows a tip to enable write access on a direct USB link z700/computer.

Thanks for your help and congratulations for this very instructive and reactive forum. We haven't got any of this kind in France.

You cannot Flash Firmware with internal memory.

You will not fix a defective camera with a firmware fix.

you have a defective grounding or mic and needs the Attention of Aiptek.

Thank you for your answer.
I'm going to mail Aiptek support to find an issue to this problem.

To own a defect should come with a great discount, keep the site posted

I will.
I'm now waiting for the aiptek support answers.

I ran a few more tests.
This annoying noise can be heard when the cam is powered on. It seems to be more an electronic noise (maybe it's what you called ground, i don't catch the exact meaning) than a mic problem.

For now, i will try to eliminate that noise from my recordings with audio sofware.

Thanks again for your very reactive support

Hi,

I also recently bought an aiptek z700 in France.
I have the same sound problem (high frequency whistle) on my recorded videos (defective suite ??).

Experienced with previous cams, i believe that this problem affects less or much every recording with an internal microphone.

I sent an email to Aiptek support but i don't hope much.
I think that the best issue is to use an external mic, which is possible with the z700.

I bought an external microphone at Aiptek Store and will keep you informed of the results.

I find this forum very useful (especially the impressive review of z700).
Thanks for sharing your knowledge and time.

Hi,

Some news from Aiptek and this sound problem.

I received a phone call from Aiptek support telling me the problem comes from the firmware version of my Z700. They told me to download and install the 2900 firmware version to solve the sound problem (strange ways, here we come :=))

Unfortunately, i can't test if it works. I can't copy the .bin file to the SD Card. I have no card reader on my laptop, so i have to connect the cam with USB link.

When i tried to write the file to the drive related to SD, i have an error message telling me it is write protected.

The switch on the SD card itself is of course unlocked and the cam writes with no problem on it.

I tried to format the SD card on the cam, then connect to the PC, but no way. I saw that a DCIM directory was created during the format process. It doesn't look like a "true" format of the memory card.

Is there a kind of write protection when you use the cam PC link to access the SD card ?

Do i have to use an external card reader ?

Thanks for your help

1. how did you format the sd card? fat or fat32.

step one cam plugged into pc/laptop, open door of cam, two windows open up int, and removable.

step two close the windows and only format removable drive of cam, by my computer/ drvie (X) right click format fat32 format start, reformat again twice is what I awlays do.

you say you tried this over and over again? yes, no?

So Aiptek States Sound issue will be fixed with FW2900

my suggestion ((idea))

Ask Aiptek for a sdhc card with the FW2900 loaded up sent to you, for all your troubles with the cam with the sound issue.

I cannot see fw2900 correcting a hardware problem.
