There is three indicators lights on the panel

Disable the joystick mouse in the center of the keyboard. Doubleclick Mouse in the Control Panel (Start/Settings/Control Panel). On the end tab, disable the thumbstick mouse. For my IBM Thinkpad, it's under UltraNav and I disable TrackPoint.

If you have access to a laptop computer that has an Infrared Port or Bluetooth communications, you can download your videos and picture files via either of these two methods. I use an old IBM Thinkpad 600 with IR port to download mine. You have to put your z525 phone into Infrared mode first, its kind of tricky with out seeing what you are doing. First, open your phone, press upper right (-) sign to get menu, click joystick control down 2 times then right 1 time. next press upper left (-) sign to select. next joystick right 4 times, and down 1 time. press upper left (-) sign, then joystick up 1 time. press upper left (-) 1 time. Your Infrared Port will now be turned on, and your I.R. enabled laptop can now receive the files from your phone. Close your phone, open it again, press upper right (-) , press joystick down 1 time, then left 1 time, then press the joystick center select button 2 times. Joystick right 1 time, press joystick select 1 time. press upper right (-) 1 time, joystick down 5 times, joystick right 1 time, joystick down 3 times, joystick center select 1 time. Hold the lower left corner of your phone toward the I.R. port of the laptop, it will receive the first photo file in your camera pictures file. Another possible method would be to obtain a usb connector cable for the z525 phone to connect it to your computer. Using the usb cable the computer would recognize the phone, you could click on the phone icon, under "MyComputer" and transfer the files to your hard drive. I hope this helps. -Mike

Hi, to set the time or date, first press the MENU button (beside the DIRECT DVD button). Nudge the joystick to the left to select which settings you want to edit. Then go up until you reach the general options. Nudge the joystick right. Move the joystick up until you see "CLOCK ADJUST". Here you can set the correct time. The light is really easy to access. In the shooting mode (where you are seeing live video from the lense), nudge the joystick down. The light should come on. Nudge it down again to put it on Auto. It will turn on/off depending on the lighting. Nudge it down a third time to turn it off. Hope this helps!
