R Images may appear distorted because of the characteristics of the
camera lens. This is not a malfunction.
R At night or when there is poor light in the area around the lobby
station, lights or white objects near the lobby station may appear
greenish. This is not a malfunction.
R Even when the lobby station's LED lights are lit, because the light
from the LED lights cannot illuminate the edges of the visible area
(the areas directly next to the lobby station), faces of people may not
be identifiable even when they are close to the lobby station.
→ We recommend installing extra lights in the area around the lobby
station.
R Images of people's faces appear dark when there is strong sunlight or
a backlight in the area around the lobby station.
→ Use the backlight compensation function.
R There is dirt on the surface of the lobby station's lens.
→ Wipe the lens with a soft, dry cloth.
R There is water condensation on the surface of the lobby station's
lens.
→ Wait for the condensation to evaporate.
R The brightness of the display is not correctly adjusted.
→ Adjust the brightness when images are displayed.
R Strong light such as sunlight is shining into the lens of the lobby
station causing images to be difficult to see on the display. (This is not
a malfunction.)
→ Locating the lobby station away from direct sunlight or changing
the angle that the lobby station is installed may help reduce this
problem.
R If the sun can be seen, its centre appears as a black dot. This is not a
malfunction.
R AC (alternating current) lights such as fluorescent lights are used
near the lobby station.
→ AC (alternating current) lights such as fluorescent lights may
cause flickering in dark environments. (This is not a malfunction.)
R The lobby station and main monitor may not be correctly connected
together.
→ Contact an authorised service centre.
R Perform the following operations.
→ Press the MRESETN button on the bottom side of the main monitor
with a pointed object. (Configured settings are not affected.)
