The supply voltage quality must
correspond to that of a typical
commercial or hospital
environment. If the user of the
device CoolTone requires
continued operation, even in the
case of interruptions in the
power supply, it is recommended
that the device CoolTone be
powered from an uninterrupted
power supply or a battery.
