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

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

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.

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.
