No! Technomad systems are designed to require zero programming or other technical setup in the field. The transmitters and receivers automatically locate and link to each other, and no programming is required. This is a critical requirement for deployed base PA systems – the simplicity of the Technomad wireless systems mean that systems can be setup quickly and reliably under dangerous or stressful conditions. Technomad’s ‘no-setup’ approach is much better than that of other systems that require complex programming in the field to use. Note also that the wireless link kits do not require a computer to operate.
