3. BASIC OPERATION
The EQ1 uses a simple ‘PRESS’ and ‘ROTATE’ system to navigate through
the various setting using the multi function knob on the left side of the headset.
3.1. Turning Headset ON and OFF
To turn the headset ON press and hold the knob for 2 seconds. You will be
‘introduced’ to the headset, and a voice prompt will announce "hours of battery
life" remaining.
The EQ1 will produce an audible beep every 5 seconds until its "paired" EQ-
Link unit is located. (Note the EQ-Link must be turned on. The EQ1 and EQ-
Link have been paired at the factory If more information on pairing is needed
please refer to section XXX for EQ-Link pairing) If your unit detects an EQ-Link
that it is not paired with, then a low tone will be heard and the headset will
continue to look for your paired device.
Once the paired EQ-Link is detected you will hear a voice prompt "XXXX" You
can then operate the EQ1 headset as you would any conventional aviation
headset. If the EQ1 does not detect its paired EQ-Link, the unit will
automatically turn off after 2 minutes.
To turn the Headset OFF, press and hold the knob, a count down will then be
initiated. (3…..2……1… Battery xx Hours). When the message “HEADSET
OFF” is heard the knob can be released. Or turn off the EQ-Link and it will
signal the EQ1 headset to power down as well

5. SYSTEM FUNCTIONS
5.1. EQ-Link
The EQ-Link is the heart of your headset system that wirelessly connects the
EQ-1 headsets and provides the interface for your radio and communications
system.
The EQ-Link must be plugged into an intercom system and will power on when
your aircraft’s communication system is energized.
5.2. EQ-Link Pairing
The EQ-Link has been paired at the factory with the supplied EQ-1 headset.
No other adjustments are required.
However if you wish to pair a headset to a new EQ-Link:
Enter Advanced menu mode and select "pairing" from the advanced menu
settings (refer to the flow chart section 10.1)
Power the EQ-Link. Either plug the link into your intercom inputs in the aircraft
or by plugging the mini USB charging cable in an appropriate power source
(USB port on your P.C. or supplied 12 volt adapter)
Ensure that the EQ-Link that you wish to pair to is set to Master.(see P13)
The headset should then detect the EQ-Link and announce the last 4 digits of
the serial number of EQ-Link. This serial number can be found on the back to
the EQ-Link. If this is the correct unit as indicated in the headset then press
the button on the headset to confirm.
Your headset is then paired to this EQ-Link and will only link to this unit when
in "Link" or "passenger" mode.

5.3. Multiple Headset Configuration and Pairing
EQ-Link will allow multiple EQ-1 headsets to be paired to the same EQ-Link
module. It should be noted that the multiple headset configuration is
intended for passenger communications only and should be plugged in
to a "passenger" input on the intercom system. EQ-Link operates in a
semi duplex mode and does not have the ability to distinguish between
pilots and passengers. Plugging an EQ-Link with multiple paired
headsets in a pilot input could potentially interfere with important VHF
communications.
For optimum performance all EQ-1 headsets should be set to "passenger"
setting as described Section 4.1 "Headset Mode"
Each EQ-1 headset will need to be paired to the EQ-Link module as described
on page
5.4. PTT Detection
The EQ-Link can detect when the aircraft PTT is activated, this is indicated by
the YELLOW LED going fully on. This can aid in the detection of PTT Faults
and also as a general PTT indication.
On each PTT press a short tone (BEEP) will be heard in the headset and
when PTT is released a short tone (BOP) will also be heard. We call these
comfort tones and they give feedback that you really have pressed and
released the PTT button in the aircraft.
Note: only available when aircraft’s headset sockets are wired for PTT
The VHF radio system has override priority and will mute all other ancillary
inputs such as MP3, cell phone UHF etc; when a PTT signal is detected on
this input. Some aircraft may not have this active on the headset sockets and
hence this feature will not work.
5.5. Optional MP3 or Cell Phone Interface
The EQ-Link has additional inputs suitable for Cell or MP3 type connections,
these are available on the 3.5mm connector at the end of the EQ Link.

Operation Manual
Page 12
ATO Aviation Inc.
Note:
During VHF reception 3.5mm Audio input is muted to the headsets, this will
always enable clear reception of all VHF radio traffic.
An optional EQ-1 Blue Tooth Module specially designed to suit the EQ-1
System is available for Cell phone interface. When using this module ensure
that the module is mounted at least 400mm away from the EQ Link to avoid
RF interference. Usually the Blue Tooth module should be positioned in an
accessible area of the aircraft.

5.6. EQ-Link Communications Settings
The EQ-Link will function at peak performance when the aircrafts
communications settings can be adjusted to suit. The EQ-Link acts as a cable
replacement for standard Headsets and as such will receive any imperfections
in the aircraft communications system. The extra quietness of the EQ1 system
means that some electrical noises that may not have been heard with other
headsets may now become audible.
Advanced features can be activated on the EQ-Link to further assist the noise
reduction performance of the system. These modes are activated by 3 fast
clicks of the STATUS button on the EQ-Link. These modes will be announced
on the paired headset for ease of use and understanding of the functions
performed.
Standard Modes include improved noise cancelling DSP algorithms.
The graph below shows a cockpit recording in a typical light aircraft. It
highlights the difference with noise reduction off to the left and noise reduction
on to the right. The dense bits in the middle are aircraft noise.

6. INSTALLATION
6.1. Installation EQ-Link
The EQ-Link system is supplied with a standard aviation cables and
connectors (jacks) to suit standard aviation connections. The EQ-Link system
will automatically power ON when the aircraft communications system is
turned on, and will automatically power off when the communications is
switched off. A permanent optional charge cable can be connected for peace
of mind to ensure the EQ equipment is always charged.
When you aircraft communications is switched off the EQ-Link and EQ1
Headset will automatically power OFF.
Simply connect your EQ-Link into where your normal headset would be
connected. The EQ-Link is supplied with Velcro for simple mounting and a
cable clip for additional support. For additional performance operation when
multiple EQ-Link modules are used on one aircraft simply set extra units to
SLAVE mode. In this mode all the units will operate as one and not interfere
with each other, their must be at lease one master in all systems.
Slave mode can be entered by pressing and holding the STATUS button for 4
seconds, the LED lights will then change every 2 seconds from Master to
Slave and announce this in the headset. When on the desired mode, just
release the button.
NOTE: A typical aircraft can only have one master and up to 5 slaves in the
single system for peak performance, in the case of more units please contact
your supplier for additional information on your options.
