Charging the Player

The players battery is recharged while the player is connected to a running computer. When you connect the player to your computer, use the supplied USB cable. When the remaining battery power indication on the upper right-hand corner of the display shows: , charging is completed (charging time is approx. 3 hours). If the remaining battery power indication is not displayed, press the HOME button of the player to display it. When you use the player for the first time, or if you have not used the player in the remaining battery power for a long time, recharge it fully (to indication of the display).
About the battery indicator The battery icon in the information area shows remaining battery charge.
As the battery power gets lower, the bars of the icon disappear. If LOW BATTERY. Please Charge. appears, you cannot use the player. In this case, charge the battery by connecting to your computer. See page 176 on battery duration.
While charging, after a lapse of time of the Screen Off Timer setting ( page 120), the screen turns off. To see the charging status or other indications, press the HOME button to turn on the screen.
Charge the battery in an ambient temperature of between 5 C to 35 C (41 F to 95 F). The number of times the battery can be recharged before it is used up is approximately 500 times. This number may vary, depending on the conditions under which you use the player. The battery indicator on the display is only an estimate. For example, one section of black in the indicator will not always indicate exactly one-fourth of the batterys charge. Do not disconnect. appears in the display while the player accesses the computer. Do not disconnect the supplied USB cable while Do not disconnect. appears or data being transferred may be damaged. The touch panel and control buttons on the player are all disabled while it is connected to a computer. If you do not intend to use the player for over half a year, charge the battery at least once per 6 to 12 months for battery maintenance.
Some USB devices connected to the computer may interfere with the proper operation of the player. We do not guarantee the recharge of the battery using personally assembled computers or modified computers. If the computer enters a power saving mode, such as the sleep or hibernation mode, while the player is connected via the USB cable, the players battery is not charged. Instead, the player continues to draw power from the battery, discharging it. Do not leave the player connected for extended periods to a laptop computer that is not connected to AC power, because the player may discharge the computers battery. While the player is connected to a computer, do not turn on, restart, wake up from sleep mode, or shut down the computer. These operations may cause the player to malfunction. Disconnect the player from the computer before performing these operations. When connected to a computer via the USB cable, the resume information of the last played song, video, photo, etc., is cleared. Reselect the desired content from the list screen.

(On the player) Photo files are displayed in alphabetical order. The files under the PICTURE, PICTURES and DCIM folders are displayed in the PICTURE, PICTURES and DCIM folders respectively. If there are any folders under the PICTURE, PICTURES and DCIM folders, they appear as folders. Tap the desired folder to display the photo files within the folder.

Check the public wireless LAN service you intend to connect to. The access point of the wireless network may be using a security protection system not supported by the player. Consult with the administrator of your network. The access point may filter access by MAC address. Check the MAC address of the player ( page 137), then register the MAC address with the access point to connect to the wireless LAN. The network settings of the access point are not correct. Adjust the settings as described in the manuals that came with the access point and in any information provided by the administrator of the wireless LAN. The player is too far from the access point. Move the player closer to the access point. Obstacles such as walls metal, or concrete between the player and access point may adversely affect the connection. Try moving the player to a different location. There is other equipment nearby using the 2.4 GHz frequency band (such as a cordless phone, a microwave oven, or Bluetooth computer equipment). Move the equipment away or turn it off. The wireless LAN service is temporarily not available or degraded. Check with the administrator of your wireless LAN service for the status.
