Cleaning the Outside of the Instrument
To clean the LCD or the outside of the instrument, turn the power off, and remove the USB-AC adapter
from the instrument. Use a damp, well-wrung cloth to clean the outside and then wipe it off with a dry
cloth. Do not use chemicals such as thinner, benzene, or alcohol. Doing so may cause deformation
and discoloring.
Cleaning the Optical Adapter and Optical Fiber End Faces
WARNING
When cleaning the light emitter, turn off the instrument to prevent the light from accidentally
being emitted from the light source port. Cleaning the light emitter with the instrument turned
on may cause the emitted light to accidentally enter the eye. This can cause eye damage or
vision impairment.

AVERTISSEMENT
Lors du nettoyage de l’émetteur de lumière, mettre instrument hors tension pour empêcher
l’émission accidentelle de lumière provenant du port de la source lumineuse. Le nettoyage
de l’émetteur de lumière avec instrument sous tension peut permettre à la lumière émise de
pénétrer accidentellement dans les yeux. Ceci peut provoquer des lésions oculaires ou une
déficience visuelle.
