storms or after power interruptions. Some surge protector manufacturers include warranty coverage for certain types of damage. Carefully read the device

warranty when choosing a surge protector. A device with a higher joule rating offers more protection. Compare joule ratings to determine the relative

effectiveness of different devices.

NOTICE:

Most surge protectors do not protect against power fluctuations or power interruptions caused by nearby lightning strikes. When lightning

occurs in your area, disconnect the telephone line from the telephone wall jack and disconnect your computer from the electrical outlet.

Many surge protectors have a telephone jack for modem protection. See the surge protector documentation for modem connection instructions.

NOTICE:

Not all surge protectors offer network adapter protection. Disconnect the network cable from the network wall jack during electrical storms.

Line Conditioners

NOTICE:

Line conditioners do not protect against power interruptions.

Line conditioners are designed to maintain AC voltage at a fairly constant level.

Uninterruptible Power Supplies

NOTICE:

Loss of power while data is being saved to the hard drive may result in data loss or file damage.

NOTE:

To ensure maximum battery operating time, connect only your computer to a UPS. Connect other devices, such as a printer, to a separate power

strip that provides surge protection.

A UPS protects against power fluctuations and interruptions. UPS devices contain a battery that provides temporary power to connected devices when AC

power is interrupted. The battery charges while AC power is available. See the UPS manufacturer documentation for information on battery operating time and

to ensure that the device is approved by Underwriters Laboratories (UL).
