HLD3 INSTALLATION
Loop Installation Options
If there is only one hearing aid wearer and they usually sit in the same seat, the loop pad can be used. The
loop pad will be most effective when the hearing aid wearer is sitting directly above it and will not be suitable
for more than one person to use.
If there is more than one person who will be using the loop or the loop pad is not suitable then the loop wire
will be used to form a loop around the room or furniture.
There are multiple ways that the loop pad and loop wire can be placed, depending on your room size, furniture
and intended use. Below are some illustrations of possible installations.
Loop pad placed
underneath the
cushion of the
chair
Loop wire shaped around the
base of the sofa to form a loop
Loop wire shaped around
the perimeter of the room
Loop pad fixed
underneath the
chair using Velcro
or placed on the
floor

HLD3 INSTALLATION
Loop Pad Installation
Place the loop pad underneath the seat that the hearing aid wearer will be sitting in. It can be placed
underneath a cushion if possible, on the floor beneath the seat, or attached underneath with Velcro. The wire
coming out of the loop pad can then be tidied by running around the edge of the room to the driver. It is ok for
the wire to go around a door frame if necessary as this wire does not produce a magnetic field.
Connect the wire to the HLD as shown. The wires can be put in either way round:

HLD3 INSTALLATION
Loop Wire Installation
The loop wire can either be placed in a section of the room or around the whole of the room. Start from where
the driver will be placed and place the loop around and back to where the driver will be.
Connect both ends of the loop to the terminal on the HLD. They can be connected either way round:

HLD3 INSTALLATION
Adjusting the HLD
•To power on the HLD turn the volume knob clockwise until the power indicator lights up
•Switch the hearing aid(s) or device to the T–coil mode
•Adjust the volume on the HLD to a level that is most comfortable for you. The TV volume control will
not change the volume of the HLD, unless you have a variable audio output on your TV. Fixed audio
output is desired
Note: If using a loop pad you will need to sit in the chair where the pad is installed to hear after
an adjustment has been made.
•Make final adjustments on the hearing aid(s) or device
•Make a note of the volume level on both the HLD and your hearing aid(s) or device so that this can be
easily adjusted to this level when it is next in use
•When not in use turn the volume knob anti clockwise until it clicks to power off

LED Indications
1. Power – when the HLD has power connected and has been switched on the power LED will show.
In standby mode the LED will flicker on once per minute.
2. Input – when the loop is connected to an audio source and there is audio coming through the input
indicator will light show.
3. Output – when there is audio being driven through the loop the output indicator will show, it will either
flash or remain constant, depending on the level. It will flash continuously when a loop isn’t connected.
