• Briey press the On/Off button twice in rapid succession to adjust side
tone. Two short, low tones will conrm that it has been selected.
• Briey press raise volume + (7.2) to increase the volume by one step.
The change will be conrmed by a brief tone.
• Briey press lower volume - (7.3) to decrease the volume by one
step. The change will be conrmed by a brief tone.
The volume can also be adjusted by holding in the relevant volume but-
ton for a longer period. A tone will indicate each step, with a lower tone
at the end of the range. It takes about four seconds to go from min. to
max. or vice versa. The volume can only be adjusted while a call is in
progress.
• Briey press the On/Off button again to switch off side tone adjust-
ment. Otherwise the adjustment mode will be automatically switched
off after 15 seconds. A short, high tone conrms that you have left
adjustment mode.
The set level is saved even when the headset is switched off or the
batteries are replaced.
D12 Switching a call from the headset to a mobile phone
This feature is provided by some mobile phones and is therefore spe-
cic to each phone.
D13 Ending a call on a connected mobile phone
• Briey press the PTT button (7.4) to end the call.
D14 Low battery level warning
When the batteries are nearing the end of their useful life the voltage will
drop, and when around ve minutes of battery life are left, the headset
will sound three short tones every 30 seconds to warn you that the
batteries should be replaced as soon as possible. The headset will be
switched off automatically when the batteries are discharged.
D15 Range indication
If pairing has already been carried out, the headset will automatically
search for the linked Bluetooth adapter or mobile phone when it is next
switched on.
Two tones of rising frequency will indicate when the Bluetooth link has
been established. If the link cannot be established, you will hear two
tones of decreasing frequency. (There will be no automatic attempt to
reconnect.)
If the range has been exceeded and the link is broken, the headset will
continue searching for the paired device for three minutes. In order to
save energy, subsequent attempts to reconnect will only be made every
15 minutes, until the link is re-established or the headset is switched off
automatically (see D1 above). If the link can be re-established, recon-
nection is indicated by two tones of rising frequency, but if no connection
is made, then the headset will continue trying to establish the Bluetooth
link with the paired adapter or mobile phone later. If the connection with
a mobile phone is broken while the Bluetooth link is established, how-
ever, no automatic attempt will be made to reconnect.
The warning signal (two tones of decreasing frequency) will stop auto-
matically if the headset comes within range again.
• Briey press the On/Off button (7.1) to switch off the warning signal.
• Briey press any of the buttons on the headset if you want to switch
the warning signal back on.
