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 ON and OFF
To turn the headset ON press and hold the knob for 2 seconds you will be
‘introduced’ to the headset, and hours of life remaining.
You will then hear an audible beep every 5 seconds until an EQ-Link unit is
located. 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.
If no EQ-Link unit is found, 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)

3.2. Volume Adjustment
The volume is adjusted by rotation of the knob, to increase rotate clockwise
and to decrease wind anti-clockwise, the level setting will be spoken to you.
The volume will always start at a level of 4 to avoid loud sounds at turn on in
your ear.
Increase and decrease by rotation and listen to the spoken indicator.
3.3. VOX Adjustment
The digital VOX system is used to turn off or close the microphone on each
headset; this in turn stops noise being transmitted to other headsets and the
VHF Aircraft radio when no conversations are taking place. This also helps by
removing the side tone in the operator’s headset.
The VOX value is adjusted in the voice menu system; this is accessed by
pressing the knob 3 times, just like mouse clicks on a computer.
The Headset will then speak “MENU MODE”.
When this is performed the headset enters the Voice Menu System,
Note;if no more actions take place then the headset will exit the menu system
after 10 seconds.
Rotate the knob for:
“VOX SETTINGS, CONFIGURATION and ADVANCED”
Press knob to confirm the menu selection.
When in the VOX menu the knob can be rotated to select the value and
sensitivity of the VOX circuits, a higher number means a louder voice is
required to activate the VOX system.
PRESS 3 TIMES

5. SYSTEM FUNCTIONS
5.1. EQ-Link
The EQ-Link is the heart of your headset system that wirelessly connects the
headsets and provides the interface for your radio and communications
system.
The EQ-Link will power on when your aircraft’s communication system
operates.
5.2. EQ-Link Pairing
To pair a headset to a new EQ-Link:
Set Headset to EQ-Link Headset mode.
Set Headset to pairing mode from Advanced Voice Menu. (section 9.2)
Power the EQ-Link by aircraft connection or charging cable.
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 mode.

Operation Manual
Lysar Industries Page 11
5.3. 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.
5.4. 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.
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 EQ approved Blue Tooth Module specially designed to suit the EQ1
System is available for Cell 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.

5.5. 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 Microphone 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.

7. HEADSET / EQ-LINK CHARGING
The EQ1 Headsets and EQ-Link have the most advanced battery monitory
and charging system of any headset system on the market today, this ensures
that your flying will be trouble free and you are able to judge the operational
time of your headsets correctly.
The headsets and EQ-Links are fitted with the latest NiMh low loss technology.
These batteries will lose approximately 1% of their stored charge per month
when not in use. Fully charged, the headsets will provide up to 28 hours of in
flight use, and up to 35 hours for the EQ-Link system.
NOTE: The built in charge capacity indicator accuracy will diminish and not
provide accurate indications of headsets and EQ-Links that are stored for
extended periods of time. Simply re-charge the system to bring back to full
accurate capacity.
The headsets and EQ-Link can be charged from the supplied wall charger by
simply plugging the connector into the headset socket, this will automatically
power the units on and begin the charging process. This charger can charge 2
headsets or 2 EQ-Links at the same time. Every minute the headset will
announce the state of charge as a percentage of charge accumulated. This
can also be gauged at any time by briefly pressing the ON/OFF control knob.
From completely discharged the headsets should take approximately 8 hours
to charge.
The EQ-Link has a green LED to show charge status, this system will blink
faster as the charge gets to 100%. Full charge is when the green LED is fully
on. When in operation the brief pressing of the button on the EQ-Link will also
announce the charge status of the EQ-Link in the paired headset speaker.
When the systems are fully charged they will go into a preserve mode to keep
the batteries at a fully charged state with no overcharging. When charging is
complete you can just remove the power and the headsets will automatically
turn off or keep in operation for in flight use.
The Headsets and EQ-Link system can also be in-flight charged for safe
uninterrupted operation with the optional USB charging adaptor.
When the remaining battery capacity falls to 20%, (approx 5 hours flight
duration) the headsets will announce a “Low Battery Capacity” warning every
few minutes.
