Bluetooth Function: Reminder
-
Using this device as a handsfree speaker may work differently
according to the phone type and brand used. When receiving a
call on an iPhone, and when you answer the call by pressing the
< > button, the device will function as a handsfree speaker.
However, when answering the call through the iPhone, the
device may not immediately work as a handsfree speaker. In this
case, after answering the call, you need to enter the “audio
source” menu on your iPhone and select DE660.

Although this device uses the best functioning original American
CSR chip, this cannot guarantee that it is compatible with all
mobile devices. In some cases this will be the result of
incompatible Bluetooth communication protocols.
