The time factor: If you have (some) power but it is just "noisy", the UPS will filter it out completely. The "time" factor only applies when the 110vac power goes out completely - or a severe "brown-out.". The UPS will (usually) "beep" (every few seconds) to let you know when it is running on it's internal battery and the "clock" (i.e., time) is ticking down. cheers, dr geep <--------------- is happy with Poser and a UPS ;=] P.S. Read the power (Watts) requirements on the name plates of your equipment and then figure out how big a UPS uinit you need. Remember, the more (UPS) Watts, the longer the "time." Happy computing ... a UPS is cheap insurance against hair loss, also. ;=]

Remember ... "With Poser, all things are possible, and poseable!"

cheers,

dr geep ... :o]
