The times below are approximated when New Song Pop Up, Clear Stereo , DSEE (Sound Enhancer), Dynamic Normalizer, Equalizer and VPT(Surround) are deactivated, and Screensaver is set to Blank. Furthermore, for videos, the time approximated when the brightness of the screen is set to 3, or when Sound Quality Mode is set to Normal Mode. The time below may differ depending on ambient temperature or the status of use. Battery life may be shortened by the radio waves generated by ambient Bluetooth devices or wireless LAN devices, or by the communication distance between the player and the communicating device.

NWZ-A826/A826K/A828/A828K/A829 3 UNLEADED SOLDER Boards requiring use of unleaded solder are printed with the lead- free mark (LF) indicating the solder contains no lead. (Caution: Some printed circuit boards may not come printed with the lead free mark due to their particular size) : LEAD FREE MARK Unleaded solder has the following characteristics. - Unleaded solder melts at a temperature about 40 °C higher than ordinary solder. Ordinary soldering irons can be used but the iron tip has to be applied to the solder joint for a slightly longer time. Soldering irons using a temperature regulator should be set to about 350 °C. Caution: The printed pattern (copper foil) may peel away if the heated tip is applied for too long, so be careful! - Strong viscosity Unleaded solder is more viscous (sticky, less prone to fl ow) than ordinary solder so use caution not to let solder bridges occur such as on IC pins, etc. - Usable with ordinary solder It is best to use only unleaded solder but unleaded solder may also be added to ordinary solder. Notes on chip component replacement - Never reuse a disconnected chip component. - Notice that the minus side of a tantalum capacitor may be dam- aged by heat. Flexible Circuit Board Repairing - Keep the temperature of soldering iron around 270 °C during repairing. - Do not touch the soldering iron on the same conductor of the circuit board (within 3 times). - Be careful not to apply force on the conductor when soldering or unsoldering. 1.
