bluetooth technology uses low-power radio technology for wireless transmission. all radio technologies are
subject to interference from other products using radio technologies commonly used in offices.
therefore, under certain conditions, you might experience some performance degradation if you install many
Jabra GO headsets in one location or if there is interference from other radio technologies. for bluetooth, those
performance degradations are typically the result of interference from other bluetooth products including Jabra
GO products and from Wifi networks. performance issues manifest themselves as audible clicks and pops but will
very seldom prevent headset operation.
the following rules of thumb will help you plan a high capacity installation to minimize interference and to ensure
an optimal audio performance (a high quality audio based on a signal-to-noise consideration).
• If you install fewer than 25 Jabra Bluetooth headsets in one area, you are advised to separate headset bases so
that they are at least 1 – 2m apart.
• If you install more than 25 Jabra GO headsets in one area, then you should observe the following conservative
planning assumptions (valid for bluetooth class 1 operation):
# for 26 – 81 bluetooth headsets in one area, ensure on average 4m 2 – 16m 2 per headset (2m – 4m base-to-
base separation).
# for 82 – 169 bluetooth headsets in one area, ensure on average 16m 2 – 25m 2 per headset (4m – 5m base-
to-base separation).
# above 169 bluetooth headsets in one area, ensure minimum 25m 2 per headset (minimum 5m base-to-base
separation).
• The planning assumptions are conservative in the sense that they assume users are on call 100% of the
time. In many cases, 50% is a better assumption, even for some contact centers, while typical office planning
assumes 10-15% call time. this reduced on-call time has an impact on the planning assumptions. If the users
are on call less than 50% of time, use the following rules of thumb:
# 26 – 81 headsets: 2m 2 – 8m 2 area, 1.4m – 2.8m separation
# 82 or more headsets: 12m 2 area, 3.5m separation
• Use of the headset’s power save mode is recommended for a high capacity installation.
the area referred to above depends on the building layout. It could be an open space office, or a set of collocated
offices separated by lightweight walls. Offices far apart, say >100m apart, or shielded by heavy concrete walls
should not be considered as one area. the above planning figures are valid if most users are near their bases
(<3m distance). If most users are >5m away from their bases, you should roughly double the recommended area.
In all cases, you should check whether a Wifi network (in particular 802.1 b, g, n type of network) is used. If Wifi
is heavily used, you may need to reduce the number of headsets to ensure satisfactory Wifi performance. Using
more than 20 bluetooth headsets with 100% call time in an area where Wifi is heavily used needs a proof-of-
concept installation.
practical customer cases indicate that bluetooth headsets scale very well in high capacity deployments.

Making and changing Connections
the headset is able to maintain up to two connections (typically to a mobile phone and Jabra lInK 350 Usb
bluetooth adapter). If you want to connect to a third device that is already paired with the headset, then turn off
the headset and the unit you wish to disconnect, then turn on the new unit to which you wish to connect and
turn the headset back on again.
another way to change the connection is to manually pair or re-pair the headset with any device not currently
connected (it does not matter if they are already in one another’s pairing tables). see also Section 7.4: Using the
Headset with Other Bluetooth Devices.
Clearing the Bluetooth Pairing Table
When you pair two bluetooth devices, each device adds the other to its own internal pairing table, thereby
enabling the two devices to connect to one another and use encrypted communication. the Jabra GO headset is
able to hold up to 8 devices in its pairing table. If you add a ninth device, the headset will automatically remove
an item from the table to make room for the new one. In this case, an item is selected for removal based on the
time at which it was last used — the item whose last use was the longest time ago is removed.
you can also clear the entire pairing table manually. to do so, use the Jabra pC suite. see Chapter 5: Installing and
Running the Jabra PC Suite for more information.
after clearing its pairing table you must re-pair the headset to each relevant device: see Section 7.4: Using the
Headset with Other Bluetooth Devices for details.
