10 Health and safety information
Precautions when using batteries
• Never use any charger or battery that is damaged in any way.
• Use the battery only for its intended purpose.
• If left unused, a fully charged battery will discharge itself over time.
• Always charge in or as close to room temperature (20 degrees Celsius) as extreme
temperatures will affect the charging capacity of the batteries.
• If Batteries will not recharge (batteries provided have a recharge life of 800 times), DO NOT
ATTEMPT to change the batteries yourself. Instead contact VALD.
Electronic devices
Most modern electronic equipment is shielded from radio frequency (RF) signals. However, certain
electronic equipment may not be shielded against the RF signals from the units.
Pacemakers
Pacemaker manufacturers recommend that a minimum of 15cm should be maintained between the
units and a pacemaker.
Hearing aids
Some wireless technology can interfere with some hearing aids. In the event of such interference,
you may wish to consult your hearing aid manufacturer to discuss alternatives.
Other medical devices
If you use other personal medical devices, consult the manufacturer of your device to determine if it
is adequately shielded from external RF energy. Your Physician may be able to assist you in
obtaining this information.
Vehicles
RF signals may affect improperly installed or inadequately shielded electronic systems in motor
vehicles. Check with the manufacturer or its representative regarding your vehicle. You should also
consult the manufacturer of any equipment that has been added to your vehicle.
