Performance Tips
The headset fit is critical to achieving
the best noise suppression and
cancelling performance. Make sure the
ear cups are centered on the ears and
sealing of the pads to the head is firm.
Your communications over the radio is
best heard when the microphone is
placed near the mouth but not touching.
Inputs from auxiliary devices such as a
music source or cell phone can be
achieved using either Bluetooth® or the
3.5 mm wired connection. The wired
connection with Bluetooth® off will
extend battery life.
For continuous peak performance the
ear seals, microphone muff and head
pad should be replaced every 18 to 24
months depending on frequency of use.
These components are not covered by
the TELY Technologies® warranty but
may be ordered via the website at
www.telytechnologies.com.
Be careful when packing the headset
components into the carrying case.
Place the microphone in last to avoid
damage to the muff.

Trouble Shooting Tips
The muting of AUX or Bluetooth®
signals by a radio signal depends on
the radio signal being loud enough to
trigger the muting. The perceived
loudness of the radio is controlled by
both the radio volume control and the
Controller roller buttons. Balance these
controls to get the desired operation.
If power does not come on when
pressing the Power Button (4) , check
the battery orientation and voltage or
check wiring connection if externally
powered.

If Bluetooth® audio is too weak or loud,
use either the source volume control
and the Controller buttons (8) and (9)
for desired performance.
If sound is only coming from one side of
the headset, change the MONO-
STEREO switch to MONO.
If stereo sound seems left-right
reversed, reverse the headset on your
head.
If ambient noise reduction seems
insufficient, make sure the ear pads are
sealed well against the head.
If your radio or intercom transmissions
are not being heard clearly make sure
the microphone is placed close to the
mouth but not touching.
