❑
If the devices are too far apart or too close together, data transfer may be
interrupted or there may be noise in the transmission. The active area of
infrared transmission extends about 39

inches (1 meter) with a radius of
approximately 15 degrees.
❑
Covering the infrared ports with your hand or any other object will disrupt
data transfer.
❑
Avoid direct sunlight, fluorescent light, or flashing incandescent light near
the infrared ports.
❑
Disable infrared communication when you are not using it to conserve
battery life.
Using a Second Battery Pack
You can purchase a second rechargeable battery pack. With two battery packs,
you can extend the time that you use your computer with battery power. When
using two battery packs, the battery pack you insert first charges first. The battery
pack you insert second charges when the first battery pack is 85 percent full. You
can monitor which battery pack is charging by observing the battery indicator
lights.
