Dropping an SAT on the floor will not kill it, but it will make a mess of the case. Being Klutz challenged I know. Magnetic fields wihin normal parameters should have no effect on the electronics. The SAT protects itself by shutting off when the battery is too low to operate tuning functions. If the battery is allowed to discharge completely you will not only loose your tunings, but the program that makes the SAT function. It will have to be send back for reprograming. Lead acid batteries were used for years because the cycle charged just fine as does your car battery. NiCad batteries without charge memories what veen around for a while, but newer SATs have Lithium recharables that hold a charge longer and do not have a charge memory. They last for about two weeks tuning about forty pianos before needing a recharge. More technical information can be had from Inventronics. Newton nhunt@rci.rutgers.edu
