However there are various external factors that may impede or restrict the operation of this product in accordance with the product’s specification. These factors include, but are not limited to: 1. Erratic or reduced radio range. Ness radio products are sophisticated low power devices, however the presence of in-band radio signals, high power transmissions or interference caused by electrical appliances such as wireless routers, cordless phones, computers, Tvs and other electronic devices may reduce the range performance. While such occurrences are unusual, they are possible. In this case it may be necessary to either increase the physical separation between the Ness receiver and other devices or if possible change the radio frequency or channel of the other devices. 2. Unauthorised tampering, physical damage, electrical interruptions such as mains failure, electrical spikes or lightning.
