the front to rear airow required for safe and reliable operation
of the amplier. It is important that the 40°C maximum operating
temperature for the amplier is not exceeded.
A mobile, laptop or desktop device with WiFi functionality and a web
browser is required. Follow the steps below.
1. Connect the [Amp Name] amplier to mains power using the
