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.

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.
