Replacing the Fluorescent Lamp This VIEWCAM uses a fluorescent lamp to backlight the LCD monitor. If the monitor becomes dark or difficult to view, the fluorescent lamp may need to be replaced. Contact the nearest SHARP service center or your dealer for further advice. Battery Pack Battery pack consumption • Recording with many starts and stops, frequent zooming, and recording in low temperatures will shorten actual recording times. Accordingly, be sure to turn off the power when not recording. Use of an auxiliary battery pack is recommended to prevent undesirable interruptions in your recording. • Do not use an insufficiently charged or weak battery pack. Use of such battery packs may cause the power to automatically stop during VIEWCAM operation to protect both the battery pack and the unit. Note: • This VIEWCAM uses a Ni-MH (nickel-metal hydride) type battery pack. Use only the SHARP BT-H22 or BT-H32 battery packs. They are designed specifically for use with this VIEWCAM. Battery pack life The battery pack has a limited service life. If the period of use becomes noticeably shorter with a normal charge, the battery pack is at the end of its service life. Replace it with a new battery pack. Extending battery pack life • It is recommended that you use the battery pack until its charge is fully drained and the VIEWCAM is inoperable before recharging the pack. • Recharge the battery pack right before recording. A battery pack stored for an extended time will naturally wear down, resulting in decreased recording time. • Do not try to recharge a fully charged battery pack before it has been discharged, as this will cause deterioration of the battery's capacity. • Store the battery pack in a dry, cool place. How to use the battery pack cover • When storing a fully charged battery pack, put the cover on it so that the "CHARGE" mark printed on the label is seen through the window, as shown. CHARGE Battery pack Label Window Cover • When storing a battery pack that is not fully charged, put the cover upside down so that only the battery pack casing is seen through the window. Caution: • For safety reasons, put the cover on the battery pack when it is not being used. If the metal parts of the battery pack come in contact with other metal items, there is a danger that a short circuit may occur. Battery power is consumed even when the VIEWCAM's power is turned off. If you are not going to use your VIEWCAM immediately, remove the battery pack (see page 7). Temperature during charging • The Ni-MH (nickel-metal hydride) type BT-H22 and BT-H32 battery packs can be charged at a temperature of 15°C to 30°C (59°F to 86°F). References 58
