Mains power quality should be that of a typical
commercial or hospital environment. If the user of the
Otowave 302 Tympanometer requires continued
operation during power mains interruptions, it is
recommended that the Otowave 302 Tympanometer
be powered from an uninterruptible power supply or
a battery
