10 UNIVERSAL INTERCOM
You can have an intercom conversation with non-Sena Bluetooth
headsets using the Universal Intercom function. Non-Sena Bluetooth
headsets can be connected to the Sena Bluetooth headset if they
support the Bluetooth Hands-Free Prole (HFP). The working distance
may differ depending on the performance of Bluetooth headset that it
is connected to. In general, it is shorter than normal intercom distance
since it uses the Bluetooth Hands-Free Prole. The Universal Intercom
affects both the phone call connection and the multipoint connection
(devices paired via Second Mobile Phone Pairing). You cannot use a
multipoint connection device while you are using the Universal
Intercom in case as below.
1. If a non-Sena headset does not support a multipoint connection,
it cannot use a phone call connection while using the Universal
Intercom.
2. As for Sena headsets, the Universal Intercom affects the multipoint
connection.

Tufftalk
28
3. If non-Sena headset (already paired as Universal Intercom with
Sena) is turned on, then the multipoint connection is automatically
deactivated. And the non-Sena headset is automatically
connected to Sena headset as a Universal Intercom. So you
cannot use multipoint connection devices, while a non-Sena
headset is turned on.
4. Even though you disconnect the non-Sena headset as a Universal
Intercom, it will not automatically restore the multipoint connection.
To restore the multipoint connection, you should turn off the
non-Sena headset rst, then try to connect to multipoint device
manually from the device screen or simply reboot the device so
that it automatically connects to the Sena headset.
10.1 Universal Intercom Pairing
The Tufftalk can be paired with non-Sena Bluetooth headsets for
Bluetooth intercom conversation. You can pair the Tufftalk with only
one non-Sena Bluetooth headset so if you pair with a different non-
Sena Bluetooth headset, the previous pairing will be removed.
1. Turn on the Tufftalk and a non-Sena Bluetooth headset that you
want to pair with.
2. Press the Jog Dial for 10 seconds to enter the conguration menu.
Rotate the Jog Dial until you hear a voice prompt, “Universal
intercom pairing”. Tap the Phone Button to enter into Universal
Intercom Pairing mode and the blue LED will ash rapidly and you
will hear multiple beeps. Please refer to
section 16.11, “Universal
Intercom Pairing”
for more details.
3. Perform the operation required for handsfree pairing on the non-
Sena Bluetooth headset (refer to
the User’s Guide for the headsets
you want to use). The Tufftalk will automatically pair with a non-
Sena Bluetooth headset when each are in pairing mode.

double tap with the second intercom friend, and triple tap with the
third intercom friend.
Non-Sena Bluetooth headsets may initiate the Universal Intercom
connection, by activating the voice dialer or using the redialing
operation. You may also disconnect the existing connection by using
the operation to end a call (refer to

for voice dialer, redialing, and ending a call).
10.3 Three-way Universal Intercom
You may make a three-way Universal Intercom connection with two
Tufftalk headsets and one non-Sena Bluetooth headset. If the intercom
connection is made, all headsets connected cannot use the mobile
phone call function since the connection between the headset and the
phone is disconnected temporarily. If you disconnect the intercom
call, the mobile phone connection is made again automatically so that
you can use a mobile phone call function.

Important Earmuff Fitting Instructions
1. Inspect the Tufftalk for dirt damage and foreign objects each time
before you place the headset on your head.
2. Ear muffs offer excellent protection if the earpieces are tted and
adjusted properly. Your ears should be completely enclosed by
the ear cushions.
3. Never attempt to physically modify, bend, or overstress the
headband which may compromise the NRR rating, proper t and
void the product warranty.

4. Regularly check the ear cushions for wear and clean them
occasionally as necessary with a damp cloth or distinct ear
cushion surface with non-alcohol PPE wipes (Do not use harsh
detergents or any solvents which may damage the ear cushion
over time). Check the ear cushions for wear. If the cushions
become hard, damaged or otherwise deteriorate, they should be
replaced promptly (Contact Sena or your authorized dealer for
exact replacement parts).
Warning
Hats, balaclavas, glasses or other items worn on the head may
potentially prevent proper sealing and reduce the level of hearing
protection signicantly which can possibly cause hearing damage.
Although hearing protectors can be recommended for protection
against the harmful effects of impulsive noise, the Noise Reduction
Rating (NRR) is based on the attenuation of continuous noise and may
not be an accurate indicator of the protection attainable against
impulsive noise such as gunre.
NRR example
1. The environmental noise level as measured at the ear is 92 dBA.
2. The NRR is (value on label) decibels (dB).
3. The level of noise entering the ear is approximately equal to [92
dB(A) - NRR dB(A)].
Caution
For noise environments dominated by frequencies below 500 Hz “the
C weighted environmental noise level should be used.”
WEEE (Waste Electrical and Electronic Equipment)
The crossed-out wheel bin symbol on the product,
literature, or packaging reminds you that all electrical
and electronic products, batteries, and accumulators
must be taken to separate collection at the end of their
working life. This requirement applies to the European
Union and other locations where separate collection
systems are available. To prevent possible harm to the environment or
human health from uncontrolled waste disposal, please do not dispose
of these products as unsorted municipal waste, but hand it in at an
