OTHER INFORMATIONRange indoors: up to 30 m (optimal conditions). The range is very dependent on local conditions, if there is metal in the vicinity for example. The thin metal coating in low emissivity energy glass has a negative effect on the range of radio signals for example. There may be restrictions on the use of the unit outside the EU. If appropriate, you should check that the unit complies with local regulations.Max. load: Never connect bulbs or equipment that exceed the maximum load of the receiver. This could lead to faults, short-circuiting or fire.Life-support equipment: Never use Nexa’s products for life-support equipment or other devices where faults or interference could have life-threatening consequences.Interference: All wireless units can suffer from interference that can affect performance and range. Because of this, the minimum distance between two receivers should be at least 50 cm .Repair: Do not attempt to repair the product. It does not contain any repairable parts.Water tightness: The product is not waterproof. Make sure it remains dry at all times. Damp will cause the internal electronics to corrode and this could lead to short-circuiting, faults and a risk of electric shock.Cleaning: Clean the product using a dry cloth. Do not use chemicals, solvents or strong cleaning agents.Environment: Do not expose the product to intense heat or cold as this could damage or shorten the service life of the electric circuits.
