Table 2: Guidance and Manufacturer’s Declaration - Electromagnetic Immunity
The ConMed Linvatec LS7700 Light Source is intended for use in the electromagnetic environment
specified below. The customer or the user of this LS7700 Light Source should assure that it is used in
such an environment.

Mains power quality should be that
of a typical commercial or hospital
environment. If the user of the
LS7700 Light Source requires
continued operation during power
mains interruptions, it is
recommended that the LS7700
Light Source be powered from an
uninterruptable power supply or
battery.
Note:
Ut
is the a.c. mains voltage prior to application of the test level.
