AUTO-CALIBRATION

Every time you replace the battery in the unit or move it to a different position or surface, the sensitivity of the touch plate will auto-calibrate for 16 seconds. This is to ensure that the transmitter is reacting correctly based on the material on which it is placed. Do not touch the transmitter during this period until the calibration has been completed.

SAFETY AND OTHER INFORMATION

Range indoors: up to 30 m (optimal conditions). The range is heavily dependent on local conditions – such as if there are any metals nearby. For example, the heavy metal coating in low-emission energy glass has a negative impact on the range of the radio signals. There may be limitations on the use of the unit outside the EU. If appropriate, check that the unit complies with the local regulations.

Max. load: Never connect lights or equipment that exceeds the maximum load of the receiver. This can result in faults, short circuit or fire.

Life-support equipment : Never use Nexa products for life support equipment or other devices where faults or disruptions can have life-threatening consequences.

Disruptions: All wireless units can be affected by disruptions that may have an impact on performance and range. The minimum distance between two receivers should therefore be at least 50~cm . Repairs: Do not attempt to repair the product. It does not contain any serviceable parts.

Waterproofing: The product is not waterproof. Make sure that it is always dry. Moisture will corrode the electronic components inside and may result in short circuit, faults and risk of electric shock. Cleaning: Clean the product with a dry cloth. Do not use chemicals, solvents or potent cleaning agents.

Environment: Do not expose the product to extreme heat or cold, as this may damage the electronic circuits or shorten their service life.
