Overview
Sonetics Wireless ComHubs are the heart of a Sonetics Portable Wireless
Communication System. SCH310 ComHubs support full duplex,
conference call-like digital communication for up to 10 Sonetics DECT7
Wireless Headsets. Radio PTT-capable headsets can be configured to
transmit on a portable radio via the ComHub. For situations that require
a large number of connected users, such as education or tour groups,
Broadcast Mode supports up to 100 users. Tethering your SCH310T with
a second ComHub (SCH305 or additional SCH310T) lets you connect two
teams in a single talk group. SCH310/T ComHubs also have DECT channel
capability, allowing users to talk on up to five different channels.
Sonetics DECT7 wireless operates on the 1.9GHz band providing secure,
interference-free, communication. With internal and external antennas,
the ComHub Base Stations configure themselves for best reception and a
line-of-sight range of up to 1,600 feet. USB programming allows complete
customization.

Setup
Orientation
The SCH310/T has the greatest range when placed in a specific
orientation. The handle on the bag should be up when in use. Refer to
the orientation stickers on the ComHub and bag for details.
Height
The higher you can safely place the SCH310/T (or its external antennas if
equipped), the better its range. Range can be up to 10 times greater
with the ComHub or antennas 10 feet high than with it on the ground.
Stickers on the sides of the case help you
position the ComHub for
best reception.
10+ feet = Best range
5-10 feet = Typical range
0 feet = Shortest range

6 | Page
Line of Sight
If you can see the ComHub when wearing your DECT7 Headset, you will
experience better reception. When you lose sight of your ComHub, your
reception may be reduced depending on your environment. Walls,
trucks, or other solid objects may degrade reception. Some objects such
as chain link fence may impact reception even though they can be seen
through.

Pairing Headsets
Pairing creates a connection between a ComHub Base Station and the
Headset. This is only required once. After pairing, Headsets will connect
automatically. You may pair any Headset to any position on either Base
Station.
Full-Duplex Pairing
1. Press and hold the desired pairing button until its link indicator begins
to flash slowly. Any previous pairing will be forgotten.
2. With headset powered OFF, place the Headset into pairing mode by
pressing the right PTT button and the power button until you hear
"base station registering".
3. The Base Station will automatically connect, showing a solid link LED.
4. If the pairing was unsuccessful, repeat Steps 1-4 above.
5. Pair any additional Wireless Headsets to remaining open positions.
Broadcast Mode Pairing
Broadcast Mode allows 100 devices to be paired. A full duplex pairing
must be present to activate Broadcast Mode. Broadcast users cannot
Radio Transmit. NOTE: Users may experience a slight loss of range when
utilizing Broadcast Mode.
Example: Position 1 has a Full Duplex Headset pairing. Positions 2-4 are
available for devices to share. Position 5 broadcasts back to the group.
1. Press and hold Buttons 4 & 5 until their link LEDs flash slowly.
2. Place the wireless device you wish to link into pairing mode (see Step
2 above).
3. The Wireless Base Station will automatically connect showing a solid
link LED on Position 5 and the device will show connected (refer to
the Sonetics device manual).

12 | Page
4. If the pairing was unsuccessful, repeat steps 1-3.
5. To pair additional devices, repeat steps 1-4.
Because Broadcast Mode Headsets share communication positions,
there can be slight delays in communication. To talk, the Push-To-Talk
button must be held until a position opens. After a Broadcast call is
made, there will be a pause in which incoming communications cannot
be heard.
To exit Broadcast Mode:
Press and hold Position 4 or Position 5 until the link LED flashes slowly,
indicating pairing mode. Power off the ComHub and power on to
complete the process.
TETHERING COMHUBS (SCH310T MODEL ONLY)
SCH310T to SCH305
Parts needed:
•(1) Cat.5e Crossover Cable*, any length

application.
SCH310T to SCH310T
Parts needed:
•(1) Cat.5e Crossover Cable*, any length
•(2) PR-RJ45 Adapter
Setup:
1. Attach the PR-RJ45 Adapters to the Cat.5e Crossover Cable
using the instructions included with the PR-RJ45 Adapter.
2. Connect a PR-RJ45 Adapter to each SCH310T ComHub as per the
PR-RJ45 Adapter instructions.
IMPORTANT NOTES ABOUT TETHERING
A minimum of 7’ of separation between the two ComHubs is
recommended.
When ComHubs are tethered, portable radio push to talk functionality is
altered: For example:
With a SCH310T ComHub tethered to a SCH305 ComHub, a portable
radio can only be interfaced to the SCH305 (not the SCH310T). Users
paired to the SCH305 ComHub can hear and radio push to talk from
their headsets. The users paired to the SCH310T ComHub will be able
to talk in full duplex mode with users from both ComHubs and hear the
portable radio communication, however, they will not be able to push
to talk over the portable radio’s frequency.
When two SCH310T ComHubs are tethered together, the users paired
on either ComHub cannot push to talk to communicate over the
portable radio. Note: each wireless headset paired to either of these
SCH310T ComHubs, needs to set their headset into “DECT Narrow” via
the Advanced Menu on the headset.
