Mains power quality should be that of a typical commercial or
hospital environment. If the user of the MicroTymp3 requires
continued operation during power mains interruptions, it is
recommended that the MicroTymp3 be powered from an
uninterruptible power supply or battery.
Note: “Dip” refers to a dip in mains voltage.

characteristic of a typical location in a typical commercial or
hospital environment.
