    Try plugging in a pair of headphones. I tried it without the speakers connected and since it found the headphones and they were OK the system came out of protect mode.

I own a Sharp DVD Micro System XL=DV60 that began to have a "protect" error message when I crank up the volume. Not sure if this applies to your system, but it could be worth a try. Before you proceed, the solution requires you to open up your system (Do not proceed if the unit is still under warranty :)).  
IF you are not experienced in opening up electronic equipment, I suggest you find somebody who does. The error on my system was caused by the cooling fan being stuck or not able to spin. The system has a sensor or sense circuitry wherein, when it detects that the "amplifier" IC heats up, it spins up the fan to cool it down. IF the system detects that the fan is not spinning during the cooling phase, it will give out the "protect" message. Note that the fan only spins when you crank up the volume. Less or 0 volume will shut down the fan due to it's "energy star" feature. One possible reason why using headphones does not show the error, since headphones require less energy that the main speakers, thus the amplifier IC does not overheat. To solve the problem, I cleaned out the dust in the system via a 1 inch wide paint brush (haven't tried the compressed bottled air used to clean computers BUT it might do) and nudged the fan. Played the system w/o a cover and observed the fan operation and so far it has solved the issue. I plan to lubricate the fan shaft with very small amount(less than a drop) of machine oil using a syringe. If it does not work, I plan to see if I could purchase a replacement motor for the fan...
Again, I have not seen the internal layout of CD-BA2100 and not sure if there is a cooling fan. But then again, it's better than having the "protect" error popping up. :) hope this helps....

I have had this camera for two years and never had a problem. Now when I switch it on the screen shows the message, " Memory card is write protected" and the camera will not function.


On the memory card is a slide lock that locks the card from being accidentally written to or erased. embossed with a lock that is unlocked/locked.
Somehow this slide lock has been moved to the write protection mode/locked. Could have happened if you removed the memory card lately.
Remove the memory card and slide the lock to unlock reinstall the card and that should cure your problem.

Power problem


If the protect function works but is causing you problems, cancelling the protection function should help, and it will be possible to enter the self-diagnostic function mode. This should disable all functions of the protection mode, excluding the 'excess electrical current detection' feature.

While pressing the "Tone Control" and "Info" keys, try pressing the power key to turn on the power. Keep pressing those 2 keys for 3 seconds longer.

this should activate the Self Diagnostic function, with your Protection Mode disabled.

in this mode the 'sleep' section on the tv's fluorescent display flashes to indicate that the mode is properly activated.

just be very aware, this function is normally there as a safety feature and i cant guarantee that disabling it altogether won't cause other problems down the road. best of luck!

How do I enter the Test Mode on my RISO 790 duplicator?


Do you mean into the unprotected mode?, if so

Turning OFF Protect mode in a Riso MZ 790u (and other models I'm sure).

1. Go to Admin Tab on the main console screen and scroll to the "Protect" button.
2. Select (press) the "Protect" button on the screen; printer will go through a reset function (takes about 3-5 seconds).
3. After printer is finished "resetting", pull out one of the master disposal boxes (doesn't matter which one).
4. Press the "Protect" button again.
5. the screen should say "Protect = Off"
6. You're done and your machine should be un-locked now.

How can we remove write protection in sony dscw320 digital camera


I'm going to assume you mean the "protect" function in the camera, rather than the whole-card "lock" function. I don't think there's a single manufacturer that makes this clear. But let me tell you their little secret... whatever you did to protect it - do it again. It's a toggle function! They wouldn't want to put "protect/unprotect" in the menu system instead of just "protect", it might look 'cluttered'. Of course, it might be more useful too. I just dug out my own Sony camera, and it's easy enough to find; be in playback mode on the picture in question, press 'menu' and scroll to the 'protect' function.

I am unable to access the internet from sleep mode Can only get on internet from shut down mode


Three possible causes of sleep mode. first, an extensive screensaver with password lock prevents display. A condition that is observable as a blankscreen also known as sleep mode. Second, a computer power saver settings that shutsdown during idleness. Third, An improper shut down of the computer would have caused a sleep mode to save the system data files.



Restoring the computer to regular functionalioty

First solving predictable sleep mode settings
1. A movement of mouse pointer across the screen should reestablish unprotected password modes
a. password protected sleep mode would display an promp message requiring key code soon after the mouse pointer has changed direction

sloving unpredictable sleep mode settings
1.A computer power saver, screen saver, or splash screen displays prevnting programs acess would require manually powering off the computer system.
a. A manual power back on of the system should restore to program functionality mode

important notes
1. contact expert technical assistance
