When the MAIN board is replaced, be sure to perform the connec-
tion check of network (wireless LAN/wired LAN).
1. Checking Method of Wireless LAN Connection
Required item:
• Wireless router with the Wi-Fi Protected Setup™ (WPS) button
Procedure:
1Place the unit close to your wireless router,
and then press the Æ(power) button to turn
on the unit.
The Æ(power) indicator starts flashing. Wait
until the indicator stops flashing. It may take
about 30 seconds. Flashing Lighting
2Press and hold the UPDATE/WPS button of
the unit until it beeps (about two seconds).

router.
Flashing Lighting
Depending on the wireless router, press and hold the Wi-Fi Protected Setup (WPS) button for a few seconds.
For details, refer to the operating instructions of your router.
When the LINK indicator lights up in orange, the Wi-Fi network connection is complete.
Checking the Wi-Fi signal strength (reception sensitivity):
The indicator of the speaker shows signal strength (reception sensitivity) by its lit status when the speaker is connected to a Wi-Fi
network and is turned on.
To receive a stronger signal
Try the following:
Change the orientation/location.
Turn off other wireless devices.
While the speaker is connected to a Wi-Fi network (the LINK indicator lights up in orange), turn on the speaker, and
then press and hold the - (volume) button and SET UP button.
The function indicators (NETWORK, BLUETOOTH, HDMI, USB-A) on the top panel start to light up.
The number of indicators lit shows the strength of the signal.
When any button is tapped, flashing stops and the signal’s strength indicator is canceled.
When no indicator is lit, the signal strength is the weakest. When four indicators are lit, the signal strength is the strongest.

Then, touch any button to cancel the Wi-Fi signal strength indication, repeat procedures from step
Ver. 1.3
