• It must be noted in advance that the LCD panel, though manufactured with
very high precision techniques, inevitably will have a very small portion of its
picture elements always lit or not lit it at all. This is not a malfunction.
• Hands-free calling prioritizes the loud side and switches between
transmission and reception automatically. The quiet side can be heard.
If there are loud noises around the unit, the sound may break up and be
dif

cult to hear.
• During communication, if you speak before the other person has
fi
nished
talking, your voice may not come through clearly. Allow each person to
fi
nish
speaking before responding.

the image on the screen.
• If light, such as illumination, enters the camera, the liquid crystal display may
