We recommend to make a test call to
another person in the same office and to
walk around during the call to find out if
any areas are out of transmission range.
If the headset leaves the transmission
range of the
base station
during a call:
• The sound quality deteriorates before
the connection finally breaks down.
• The PHONE LED
쐋
turns off to indicate
that the headset is out of the base
station’s transmission range.
• The headset LED flashes blue
twice
every 5 seconds indicating that the
headset is out of the base station
transmission range in standby mode.
If you get back into the transmission
range within 40 seconds, a ring tone is
heard in the headset. To resume the call:
왘
Press the headset hook button.
If the headset leaves the transmission
range of the
mobile phone
during a call:
• The sound quality deteriorates before
the connection finally breaks down.
• Your mobile phone or Bluetooth
device displays the loss of connection.

automatically or requires an acknowl-
edgement to do so.
