Safety
Pacemaker Safety Guidelines
Do not use the Helix HD near inadequately shielded medical devices. There are 2 magnets located within the base of the Helix HD and 3 in the
control pad. The magnets used are: Neodymium N42 22 x 11 x 2 mm.
If you have a pacemaker fitted please consult the manufacturer’s
guidelines for safe operating distances. Do not place the control pad or Helix HD directly on your chest.
General Safety Guidelines
Please handle the Helix HD with care as rough handling may
damage internal components and will void your warranty.
Always operate the unit in a place where the temperature is between
10°and 35°C (50°and 95°F). Do not expose to excessive heat, cold or direct sunlight.
Keep the unit away from wet areas, rain, and other sources of fluid,
moisture and chemicals. Do not submerge the unit.
Do not attempt to repair the unit; any unauthorised attempt will void
the product warranty. Please contact your distributor.
Use only the supplied power adapter. Always unplug the Helix HD before cleaning. Only use a soft damp
cloth to clean the exterior. Do not use cleaning agents or abrasive materials as they will damage your unit.
Please be aware of the risk of explosion if the battery is replaced by
an incorrect battery type.
Use of the Helix HD other than as described in this manual will
exclude it from warranty.

2. Helix HD control pad (with magnetic control pad overlay).
3. 2 x AAA batteries.
4. HDMI cable.
5. Power supply.
6. Laminated Quick Reference Guide.
7. User Manual.
If any of these items are missing from your box, please contact your local distributor immediately.
7
Unpacking
Carefully open the box and remove the Quick Reference Guide and the User Manual. Remove the top foam sheet. Take out the HDMI cable (in plastic bag).
Lift the Helix HD out of its box (the control pad is located under the camera arm in the transport position). Place the Helix HD with its foam base down, onto a flat surface.
Remove the power supply and 2 x AAA batteries from the small compartment at the end of the box.
Positioning Helix HD for use
When placing the Helix HD onto a surface for use, ensure it is clean, flat and large enough for you to position the items you wish to view under the camera head. For optimal image quality try not to place the Helix HD directly underneath any bright lighting or direct sunlight.
Unfolding Helix HD
1) Place the Helix HD on a flat stable surface.
8
2) Place one hand on the base and use your other to lift the front narrow section of the camera arm. Raise the camera arm from its transport position to the second (high) click position (approximately 30 degrees).
3) Grasp the top of the camera head (underneath the camera arm) and carefully rotate it downwards, towards you and up (approximately 160 degrees) until it is parallel to the base of the unit. This is its first click position (high), used for lower levels of magnification. For more information please see Adjusting camera head height on page 12.
4) Remove the control pad from its stowed position.
9
Folding Helix HD for transport
To fold the Helix HD for transport, please carefully follow the unfolding steps in reverse order.
Plugging in:
All connections for the Helix HD are located on the rear panel of the unit.
Display connection
IMPORTANT:
Before inserting the HDMI connector, make sure that the flat edge of the HDMI connector is facing upwards. Damage caused by incorrect insertion will void your warranty.
1) Insert one end of the HDMI cable into the MON connection located
on the bottom left of the rear panel.
2) Insert the other end of the HDMI cable into a suitable display (TV
screen or computer monitor).
10
HDMI Switcher connection (if required)
The Helix HD has an integrated HDMI switcher that can be used to connect an additional video device such as a digital TV box or DVD player. This function simplifies switching between the Helix HD and the additional device. It is also useful if you have no available HDMI connections on your chosen display.
1) Insert the HDMI cable from your existing device e.g. digital TV box
or DVD player, into the IN connection.
2) To show the connected device on your display either switch off the
Helix HD, or press the external Input Select button located on the top left of the Helix HD Control pad explained (see on page 13). The Helix HD must be connected to the mains and the mains power switched on for the HDMI switcher to function.
Power connection
1) Insert the round connector from the power adapter into the round
PWR connection on the right-hand side of the rear panel.
2) Insert the mains plug into a wall socket and ensure it is switched on.
11
Insert batteries into the control pad
Remove the battery cover located on the underside of the control pad.
Remove the 2 AAA batteries from their plastic film.
Insert 2 AAA batteries into the battery compartment matching the – and + symbols correctly.
Turning on / off
The on / off rocker switch is located in the centre of the underside of the camera arm approximately 12cm (4.7 inches) from the back of the unit and 22cm (8.7 inches) from the front.
To turn the Helix HD on, rock the switch away from you.
After turning on, the Helix HD will take approximately 10 seconds to show the Helix HD logo on your display.
If nothing appears on your display check that the correct input source is selected (for further details please consult your display’s user manual).
To turn the Helix HD off, rock the switch towards you.
12
Positioning documents
The Helix HD cameras are located in the underside of the camera head. Place the document / object on the base, with the area you are wanting to view directly underneath the camera head.
Adjusting camera head height
Helix HD features 2 camera head heights: high and low. The high position is for lower levels of magnification. The low position is for higher levels of magnification. It is important to note that for both positions the camera head should always remain parallel with the base.
Lowering camera head (higher magnification)
With the camera head and camera arm in the high position, grasp the sides of the camera head and lower the camera arm until it clicks into the first (low) click position.
Next, raise the camera head so that it remains parallel with the base.
Raising camera head (lower magnification)
With the camera head and camera arm in the low position, grasp the sides of the camera head and raise the camera arm until it clicks into the second (high) click position.
Next, lower the camera head so that it remains parallel with the base.

Hints and Tips - Troubleshooting
The unit does not turn on
Check the connection to the power adapter on the rear panel. Ensure the power adaptor is plugged in and the mains power is
switched on.
Ensure the unit’s rocker switch is on (rock the switch away from
you).
Nothing appears on your display
Ensure that the HDMI connection is fully inserted into the MON port
located on the rear panel of the Helix HD.
Check that the opposite end of the HDMI connection is fully inserted
into the appropriate input on your display.
On your display ensure that HDMI is selected as the input source.
Please consult your display’s user manual for further input
instruction.
If you have an additional video device connected to the IN port at the
rear of the Helix HD, ensure that the HDMI switcher has been
selected to display the correct source (see page 10).
The image does not change
Ensure Freeze mode is not active (snowflake icon in the top right
corner of your display); press or rotate any control pad control to
deactivate Freeze mode.
Smudges or blemishes appear on the display
Turn off the Helix HD and clean the camera lens (the underside of
the camera head) with a dry lint free cloth.
Does not focus correctly
Ensure the handwriting mode is not selected (see page 14). Check that the item you are trying to view is not too close to the

head).
22
Make sure that you have the Helix HD positioned at its correct height
position for the level of magnification you require (see page 12).
Control pad is not working
Ensure the batteries are located correctly in the control pad battery
compartment located on the underside of the control pad.
