Before you can use this product
Before you can use your smart speaker, you must have the following:
●A broadband Internet connection (not required for Music Player functions).
●A router (or equivalent wireless access point) providing a WiFi signal or Ethernet connection, connected to your
broadband Internet Service Provider. The broadband modem, router and wireless access point will often be a
single combined unit supplied by your Internet Service Provider or bought from a computer store.
●A Smart phone or tablet which uses either the Android operating system (version 4.0.3 or later) or Apple iOS
(version 8 or later).
●If your wireless network requires a security password to allow connection, then you need to know the WEP,
WPA or WPA2 key used for encryption so that you can get the speaker to communicate with the network.
●If you choose to connect the speaker to your network using a wired Ethernet connection, then an Ethernet cable
of appropriate length will be needed.
The speaker's WiFi system is compatible with 802.11b, g, n or a networks and can use 2.4 GHz or 5 GHz WiFi
frequency bands.
If connecting using WiFi, the speaker will typically work within a 10-20 metre radius from your wireless router or
access point. The actual range achieved will depend upon the building type, other nearby wireless networks, and
possible interference sources.
IMPORTANT: Before you continue, make sure that your router (or access point) is powered up and working with
your broadband Internet service (use your computer, smart-phone or tablet to verify this). To get this part of the
system working you must refer to the instructions supplied with those items.
