Setting up the FLX 70
Charging the battery in the headset
If you charge the battery for the first time, allow charging for at least
3 hours without interruption. Later, 2 hours suffice to fully charge the
battery.
To charge the battery in the headset:
fTake off the headset and switch it off (see
page 12).
fConnect the USB charging cable to the
socket for power supply 쐏.
fConnect the USB plug of the USB charging
cable to:
–either the USB socket of the FLX 70 power
supply
–or a USB socket of a computer
–or the USB socket of the FLX 70 car charger unit (available as an
accessory)
fConnect either the power supply or the car charger unit to the ap-
propriate power outlet.
If the battery was completely drained, the LED 쐋flashes red in the
beginning of the charging process. During charging, the LED 쐋lights
up red. When charging is complete, the LED 쐋lights up blue.
The charging process cannot be started during an ongoing call. A fully
charged battery provides a talk time of up to five hours or a standby
time of up to 100 hours. When the battery is about to run flat:

•The LED 쐋flashes red.
•Three beeps are heard in the speaker 3 times with an interval of 15
seconds and thereafter with an interval of 2 minutes.
•Less than 10 minutes of talk time are left.
Switching the headset on/off
fPress the hook button 쐄for more than 3 sec. until the LED 쐋lights
up blue.
The headset is switched on. The LED 쐋indi-
cates the current operating mode:
–If the LED 쐋flashes slowly in blue, the
headset is already paired to a mobile
phone. The headset is therefore ready to
use.
–If the LED 쐋flashes alternatingly in red
and blue, the headset is not yet paired to
a mobile phone. Pair it as described under “Pairing the headset to
mobile phones or other Bluetooth devices” on page 13.
–If the headset is already paired to a mobile phone and if there is
an incoming call on your mobile phone, the call is answered imme-
diately by a single tap on the hook button 쐄.
To switch off the headset:
fPress the hook button 쐄for more than 3 sec. until the LED 쐋
flashes red and then turns off.
All settings are saved. The battery lasts longer, if you switch off the
headset when you are not using it.

Pairing the headset to mobile phones or other Bluetooth
devices
Pairing to a mobile phone
To be able to use the headset, you must first pair it to your mobile
phone or a similar device with a Bluetooth hands-free or headset profile.
Once you have paired the headset to a mobile phone, the headset is
connected automatically each time this mobile phone and the headset
detect each other.
fMake sure the headset is switched on and placed close to your mo-
bile phone.
–If you have not yet paired the headset to a mobile phone, the
headset enters the pairing mode automatically.
–If you have already paired the headset to
another mobile phone before, you have to
enter the pairing mode manually by first
switching off the headset and then
switching it on again and keeping the
hook button 쐄pressed for 6 seconds.
–As soon as the headset is in the pairing
mode, the LED 쐋flashes alternatingly in
red and blue.
fOn your mobile phone, start a search for Bluetooth devices (see the
manual of your mobile phone) and follow any instructions displayed
on your mobile phone display.
fOnce the headset is detected by your mobile phone, select “FLX 70”.
When the Bluetooth connection is successfully established, the head-
set is identified as “FLX 70” in the mobile phone’s display.

쐄

fWhen your mobile phone prompts a keyword, enter four zeros
(0000).
If pairing was successful, the LED 쐋flashes slowly in blue.
Once paired, your mobile phone will be able to transfer the call audio
to the headset – either automatically or manually (please see your
mobile phone’s manual whether the call audio is transferred auto-
matically or manually). Most mobile phones show a headset symbol
in their display, if successfully paired.
Pairing to other Bluetooth devices
If you wish to pair the headset to other Bluetooth devices, please see the
Bluetooth device’s manual.
Pairing to several mobile phones
If you wish to pair the headset to a second mobile phone, you first have
to disconnect from the first mobile phone (see the manual of the first
mobile phone). The headset saves up to four pairing profiles. As soon as
the headset is switched on it tries to connect to the mobile phone that it
was last connected to. If this mobile phone is not detected by the head-
set, you can manually connect it with one of the other three mobile
phones (see the manual of the respective mobile phone).
