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. 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). HINT: 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.
