SAFETY AND INFORMATION

Indoor range: up to 30 m (optimal conditions). The range is strongly dependent on local conditions, such as the presence of metals. For example, the thin metal coating in Low-emissivity (Low-E) glass has a negative impact on the range of radio signals.

There may be restrictions on the use of this device outside the EU. If applicable, check whether this device complies with local directives.

Maximum load: Never connect lights or equipment that exceed the maximum load of the receiver, as it can result in defects, a short circuit or fire.

Life-support: Never use Nexa products for life-support systems or other applications in which equipment malfunctions can have lifethreatening consequences.

Interference: All wireless devices may be subject to interference, which could affect performance. The minimum distance between 2 receivers should be at least 50 cm.

Repairing: Do not attempt to repair this product. There are no userserviceable parts inside.

Water-resistance: This product is not water-resistant. Keep it dry. Moisture will corrode the inner electronics and can result in a short circuit, defects and shock hazard.

Cleaning: Use a dry cloth to clean this product. Do not use harsh chemicals, cleaning solvents, or strong detergents.

Environment: Do not expose the product to excessive heat or cold, as it can damage or shorten the life of electronic circuit boards.
