Modifications to battery charger:
Never attempt modification to battery charger electric circuit or connector.
Never connect to electric components other than those manufactured by Helitowcart (Vanair inc.).
Always immediately replace any damaged electric cable.
Always perform maintenance to battery charger as recommended by Helitowcart.
Cleaning and Maintenance
Clean battery charger using a soft rag and diluted soft soap.
Do not use alcohol or thinner based detergents.
Regularly carry out maintenance as recommended by Helitowcart.
About electromagnetic energy
All electronic instruments which transmit remote information are generally apparatuses which emit some
radio waves in the environment. These radio waves are called "electromagnetic energy ". The proper
operation of an electronic instrument can be deteriorated by this electromagnetic energy field. It is what
we call "an electromagnetic interference ". The stronger the intensity of energy, greater the risk of faulty
operation of the apparatus. This energy is measured in volt per meter (V/m).
All motorized Helitowcarts are subject to be affected by these interferences. However, current technology
makes it possible to immunize them against these risks. It is what is called their electromagnetic level of
immunity to the interference, measured also in volt per meter (V/m).
The controller has been tested for compliance with EC directive 89/336/EEC, and the EMC requirements
of PREN12184. The guidelines in this section will help you to make sure that your vehicle installation will
easily meet the requirements of the directive.
Electromagnetic energy effects-caution
Waves emitted by the following devices can affect the correct operation of the battery charger:
Radio and television stations,
Amateur radio,
Radio transmitters and receivers,
Cellular phones.
Using transmitters and receivers
Avoid proximity to sources of electromagnetic emissions.
