1) Align white indent marker on Amp Module with indent marker on main PCB; alternately position of label on the top of the module; incorrectly replacing the Module 1800 in the PCB slot will result in its destruction. 2) All AC powered test instruments (meters, oscilloscopes, etc.) must have a floating ground, i.e. be connected to an isolation transformer. 3) Align and position the Amp Module before soldering. 4) Attach the amp Module with the mounting screws before soldering or powering up. 5) Use only rosin-core or non-acid core solder; thoroughly de-flux the surfaces after soldering.
