Dell S500 Projector - Manual (Page 44)

Charging the Interactive Pen Battery (for
S500wi only)
When the Interactive Pen amber battery light starts to blink, its internal battery is
low (If the battery is fully discharged, you will not be able to turn the Interactive
Pen on by pressing its nib, left, right or set function buttons).
To charge the battery, connect a mini USB cable between the Interactive Pen and
your computer or laptop (If connecting to computer or laptop, make sure the
computer or laptop is powered on). The battery light will stay on while the battery
is charging and turn off when the battery is fully charged.
When charging is finished, you can unplug the mini USB cable (or keep the cable
connected and use the Interactive Pen while it's charging).
NOTE: For first time use, it takes at least 4-5 hours to fully charge the battery. A
fully charged battery will allow 25 hours of non-stop use or up to 4 weeks in
standby.
CAUTION: The lithium battery is only rechargeable and is not user replaceable
or serviceable. If your Interactive Pen cannot charge, contact Dell (See
"Contacting Dell" on page 125).
CAUTION: Always use the included mini USB cable and your computer (or use
the Docking Charger) to charge the Interactive Pen. The Docking Charger is not
shipped with your projector. You can purchase it on the Dell website at
www.dell.com.
