As we summer desert dwellers struggle to survive record high temperatures and monsoon storms, please take a little time to consider the seasonal hazards your electronic servants face. Power surges and outages challenge the growing numbers of electronic minions in your household on a daily basis. Your expensive and important appliances should have surge protectors in place; more sensitive or critical devices are best protected by uninterruptable power sources, a.k.a.battery backup systems. These protective devices do not last forever; replacing every few years or after a single severe power surge is routinely advised. If you will be away from home for a prolonged interval, simply unplugging unused devices is safest of all.
