as when switched-off. The hands-free function cannot be used when it
is turned off.
7 Connecting via Bluetooth
Ensure the headset is switched off first. Press and hold the on/off button
for about 6 seconds till the LED indicator starts to flash in red and blue
alternately. Enable the Bluetooth on the device that you want to connect
with the headset. Carry out a search now and connect to the device "CSL-
450". Enter "0000" if you are prompted for a security code.
Note: The Bluetooth pairing mode is disabled for security reasons if con-
nection is not established even after several minutes. Please carry out the
steps mentioned above once again if pairing failed.
Please proceed as follows to connect two devices at the same time to
your CSL-450 headset: Connect your first device to the CSL-450 headset
as usual. Then press the "Increase volume" and "Decrease volume" but-
tons simultaneously to use the function for connecting the headset to
two devices. Then, search for the model "CSL-450" on your Bluetooth en-
abled device. Here, the device that was paired first always has priority. If
it is disabled, then you can also make phone calls or play music with the
second device.
