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.
YOUR INSTALLATION IS NOW COMPLETE…………

8. HINTS AND TIPS ON OPERATION.
Make sure that the headset and EQ-Link units have fully charged batteries.
Make sure the EQ-Link 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 micro-light in full climb out may require a headset 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 and the aircraft communications module to suit
the user.
NOTE: it is recommended that you turn the aircraft’s communications system
VOX (or squelch) system off or low, as the headsets will now control this for
you.( ** In the case of multiple EQ1 systems)
Your EQ1 and EQ-Link system will come from the factory already paired, if this
is required to be done again or you have purchased an EQ-Link separately,
follow the paring steps on page 10.
DO NOT LEAVE YOUR HEADSET IN FULL SUN OR CLOSED HIGH
TEMPERATURE ENVIRONMENTS.

and sensitivity of the VOX circuits, a higher number means a louder voice is
required to activate the VOX system.
