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 a base unit is
located. The Base unit that is nearest your headset will be the first to be locked
onto. Optionally the base controller identification may also be spoken to you, in
normal cases this is the aircraft type and registration ID.
If this is option is programmed and not the same as your headset then you
have an option to release from this base and search for another. The
instructions to confirm selection are spoken to you.
If no base 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… Batttery xx Hours)
When the message “HEADSET OFF” is heard the knob can be released.

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 large sounds on 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
reduce noise in the operators headset due to increased side tone.
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, 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.
“ONE, TWO, THREE……….…..TEN”
When the desired VOX setting is reached press the knob to save and
confirm the setting.
The Headset will then automatically leave the menu system and return to
normal operation.
PRESS 3 TIMES

4. ADVANCED OPERATION
When in the voice menu system more advanced options can be configured,
these include headset type, configuration and Base Controller Programming.
4.1. Headset Type
Enter the programming voice menu as above.
Rotate the knob for:
“CONFIGURATION”
Press knob to confirm the menu selection.
Rotate the knob for:
“MASTER, PILOT, CO-PILOT and PASSENGER”
Press knob to confirm the menu selection.
When in MASTER Mode the headset acts like a Base Controller and can
communicate directly with other headsets. We call this PEER to PEER mode.
This can be used when headsets need to talk directly and no other
transmissions are required on other equipment such as VHF Radio.
When in PASSENGER mode the headset functions as per normal until the
VHF radio PTT is activated, in this case the Passenger Microphone is muted
so that any conversations by the passenger is not sent on the VHF Radio.

4.2. Base Programming (optional)
Enter the programming voice menu as above.
See details in section 9 for flow operation.
NOTE: Only a Headset Configured to “PILOT” has this programming ability to
update the BASE CONTROLLER.
This programming is optional and is only used to distinguish aircraft from each
other in busy situations or close start up proximity. It can also be used as a
comfort factor that you are locked onto the correct Base Controller.
Rotate the knob for:
“ADVANCED”
Press to confirm the menu selection.
Rotate the knob for:
“AIRCRAFT TYPE, Registration Set 1 to 4 and PROGRAM”
Press to confirm the menu selection.
When in the AIRCRAFT TYPE menu rotate the knob to best describe your
aircraft and press the knob to confirm your selection.
Use the Registration Set 1 to 4 menu options program the last 4 digits of your
aircraft registration.
Use the PROGRAM menu to update and confirm the settings to the Base
Controller, YOU MUST BE Locked onto the base controller you wish to update
at this time. Any headset can be configured, but only the pilot will remotely
update the Base Controller.

5. SYSTEM FUNCTIONS
5.1. Base Controller
The Base Controller is the heart of your headset system and connects the
headsets and provides the interface for your radio system.
The Base Controller supplies switched power to your aircraft VHF radio, and
also controls when it turns its own power off. This will occur 2 minutes after the
aircraft ignition is turned off. This time is so that the headsets and VHF radio
remain active to enable disembarkation from the aircraft with the headsets
active.
5.2. Remote Wireless PTT
Your system is supplied with one wireless PTT controller, additional Wireless
PTT’s can be purchased and a maximum of 4 Wireless PTT modules can be
added to your system. Each PTT is individually coded so that it will not operate
the PTT on other aircraft in the area. If a new PTT is to added into the system
then the new device must be “paired” with the Base Controller for it to function.
The “paring” process can only take place within 15 seconds of the Base
Controller being turned on from a cold start.
To pair a new PTT, turn the Aircraft power on so that the Base Controller
becomes active and within the start up period of 15 seconds press the new
PTT at least 10 times. After this the new PTT will become registered and
function in your system.
The wireless PTT’s have been designed for over 1 million key presses, in the
advent of the battery going flat a voice announcement will take place on every
PTT press. In this event the PTT needs to be replaced.
Remember that the Base Controller takes 2 minutes to turn fully off when the
Aircraft ignition is turned off. You must wait this time for a cold start. You can
determine this as the VHF radio is turned off by the Base Controller at this
time.

Operation Manual
Page 10 Lysar Industries
5.3. Wired PTT
The Base Controller is supplied standard with the VHF wired PTT input, this
can be switched to any convenient ground point on the Aircraft for activation.
Additional inputs and outputs are provided for an auxiliary radio system to run
in parallel with the VHF system.
The VHF radio system has override priority and will mute all other inputs when
a signal is detected on this input.
All PTT signals have a stuck PTT timer that will release the PTT to the VHF
radio if any PTT switch gets held ON more than 15 seconds.
5.4. MP3 or Cell Phone Interface
The Base Controller has additional inputs suitable for Cell or MP3 type
connections, these are available on AUX1 and AUX2 inputs and outputs. In
addition MP3 or Cell can be connected with the optional cable to each
headset.
AUX1 is used for Cell Phone Interface
AUX2 is used for MP3 type interface
Note:
During VHF reception AUX1 and AUX2 are muted to the headsets.
During Headset VOX operation AUX2 is muted to the active headset.

6. INSTALLATION
The EQ1 system is supplied with a standard cable to suit XCOM or Micro-Air
VHF radio’s, other cables or adaptor harnesses are available from the
manufacturer to suit other VHF Radio Types.
Only 3 wire connections are needed to complete the installation, these are
battery positive (RED), battery negative (BLACK) and an ignition feed
(YELLOW) from the master switch or ignition circuit. The DB15 harness is also
plugged into the VHF Radio.
If the wireless PTT is to be used, then no other connections need be made. If
a hard wired PTT is already fitted then this can be connected to the “BLUE”
PTT in wire. The other side of the PTT switch should be connected to ground
in a suitable location.
The EQ1 Base Communications module comes with double sided Velcro, and
can be positioned in a convenient location as required and out of the way.
Ensure that the locating screws are tight on both the DB15 (VHF Radio) and
the DB25 (Base Controller).
YOUR INSTALLATION IS NOW COMPLETE…………

7. HEADSET CHARGING
The EQ1 Headsets 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 are fitted with the latest NiMh low loss technology and these
batteries will loose approximately 1% of their stored charge per month when
not in use. Fully charged the headsets will provide up to 24 hours of in flight
use.
NOTE: The built in charge capacity indicator accuracy will diminish and not
provide accurate indications of headsets that are stored for extended periods of
time. Simply re-charge the system to bring back to full accurate capacity.
The headsets can be charged from the supplied wall charger by simply
plugging the connector into the headset socket, this will automatically power
the headset on and begin the charging process. This charger can charge 2
headsets 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.
When the Headsets are fully charged they will announce this and 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.
The Headsets can also be in-flight charged for fail-safe operation with the
optional charging adaptor.
When the remaining battery capacity falls to 20% (5 hours flight duration), the
headsets will announce a “Low Battery Capacity” warning every minute.

8. HINTS AND TIPS ON OPERATION.
Make sure that the headset units have fully charged batteries.
Make sure the Base Controller is not behind metal walls in the aircraft as this
will limit the effective range of the system.
Make sure the VHF antenna or other high powered transmitters are a least 2
meters from the headset system. If the VHF antenna is too close to the
headset then Radio frequency feed back will occur in the headset when
transmitting on VHF. This will result in an echo like feedback in each headset
and live echo on VHF transmit frequencies.
Set the VOX operation to suit the noise profile of the Aircraft, a high noise
aircraft like a microlight in full climb out may require a vox setting of 6 to 8.
Ensure the correct position of the EQ1 microphone, one finger width from the
mouth. This is very important for correct operation. Make sure you are
speaking into the correct side on the microphone, this is marked with “EQ”
and should face the mouth. As this system is designed for high noise all noises
away from the microphone are attenuated. Getting the microphone in the
correct position is VERY IMPORTANT.
Set the VHF Radio Squelch OFF and listen to the noise, then adjust the VHF
radio Volume for a comfortable level. Reset the VHF radio squelch as
required. The overall volume of all conversations and the VHF radio can then
be controlled on each headset to suit the user.
If many EQ1 units are operating in the same area, then you can set you own
ID of the aircraft to enable better selection of your desired aircraft base
controller.
DO NOT LEAVE YOUR HEADSET IN FULL SUN OR CLOSED HIGH
TEMPERATURE ENVIRONMENTS.
