mobile phone and select connecting in
thesubmenu,thentheunitwillappear
CONNECT.Otherwise,thereisnovoice
comingoutwhencommunicating,though
the mobile phone has already displayed

itplaybackA2DP, youmustndtheunit
name in the phone’s menu and reconnect
(check your mobile phone whether has the
A2DP&AVRCPfunctions).
Bluetooth Operation
2. When pairing, some types of mobile
phonehintthathowtooperate,for
example,whenyoumakeaphonecallby
theunit,ifthemobilephonevoicedosn’t
betransferredtotheunit,novoicecomes
out.
3. Dependingonthemobilephone,ifprivate
modeisselected,whenyoumakeaphone
callbytheunit,orreceive,thevoicewould
be transferred to the mobile phone. But
sometime the Bluetooth maybe disconnect
tillthecommunicationends,thenconnects
your mobile phone to the unit automtically.
Some mobile phones maybe need pair
again.
4. Formobilephone,theBluetoothdevice
name must be primary symbols or
numbers.Otherwise,someunpredictable
issues may occur during the Bluetooth
devices connecting and making phone
call.
5. AfterCONNECT,ifnosoundproduced,

Please Recycle Your Spent Batteries
Batteries should not be disposed of in unsorted
municipalwaste,butseparatelycollectedtofacilitate
the correct treatment and recycling of the substances
they contain. The recycling of batteries ensures the
recovery of these valuable materials and prevents
any potentially harmful effects upon both the
environment and human health.
Please contribute to battery recycling by segregating
all spent batteries and actively participating in their
collection and recycling. Various battery collection
schemes will be in operation in different areas of
thecountry.However,batterycollectionbinswill be
available at retail stores that sell batteries as well as
atschools,librariesandotherpublicbuildings.
