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 doorphone,
lights or white objects near the doorphone may appear greenish. This
is not a malfunction.
R "Automatic illumination" is set to "Disable".
→ Change the setting to "Enable".
R Even when the doorphone'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 doorphone), faces of people may not be identifiable
even when they are close to the doorphone.
→ We recommend installing extra lights in the area around the
doorphone.
R Images of people's faces appear dark when there is strong sunlight or
a backlight in the area around the doorphone.
→ Use the backlight compensation function.
R There is dirt on the surface of the doorphone's lens.
→ Wipe the lens with a soft, dry cloth.
R There is water condensation on the surface of the doorphone'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 doorphone
causing images to be difficult to see on the display. (This is not a
malfunction.)
→ Locating the doorphone away from direct sunlight or changing the
angle that the doorphone is installed may help reduce this problem.
R AC (alternating current) lights such as fluorescent lights are used near
the doorphone.
→ AC (alternating current) lights such as fluorescent lights may cause
flickering in dark environments. (This is not a malfunction.)
R Change the zoom position setting to a suitable position.
→ Configure the "Zoom position settings" settings.
R The ringtone volume is muted.
→ Activate the sound for the ringtone.
