QUESTION ANSWER
Where are the proper place to
install a washer or dryer?
• Since a washer or dryer is heavy and connected with water, it should
be installed in the proper place. Installing the AP near the washer or
dryer is recommended. You can check the signal strength through
the setup screen of the washer or dryer or a smartphone.
• Since the performance is seriously a ected by a door or steel wall,
install the product in an open place. If there is door in front of the
installed product, open the door when using the product.
• Do not place an object maden with steel or glass in front of the front
LCD of the washer since it blocks the radio signal.
• Note that the radio signal may be weaken or interfered and the
communication with the smartphone may fail when a microwave oven
is used in the house.
• Install the washer or dryer so that the front of the product faces the
AP if available.
How can I connect the
washer or dryer with a
smartphone stably?
• When the signal strenth that is displayed on the LCE of the washer
or dryer is weak, the control may fail. Check the mark as follows or
measure the signal strength.
• At least 3 antenna bars should be displayed on the LCD of the
washer or dryer.
• At least 3 antenna bars for the Wi-Fi connection should be
displayed on the smartphone.
• When the signal strenth is measured with a smartphone app that
shows the Wi-Fi signal strength, the signal strength should be
stronger than -65 dBm. (E.g. -60 dBm and -50 dBm are stronger
than -65 dBm.)
What should I have to
do when the number of
the antenna bars that are
displayed on the LCD of the
washer or dryer is 1?
• When the signal strenth that is displayed on the LCE of the washer
or dryer is weak, the control may fail. In this case, take the following
measures for normal operation.
• Move the AP closer to the washer or dryer.
(At least 3 antenna bars should be dislayed in the network setup
of the washer for proper operation.)
• Since old AP may provide lower performance, use new one if
available.
• Stand the antenna of the AP if available so that the radio signal is
more easily propagated.
