The ideal length of exposed wire in the stripping
process is 3/16" (5 mm). If longer than 3/16", the
exposed wires may touch, causing a short circuit.
If shorter than 3/16", the wires can be easily pulled
out even if tightly fastened.
Do not tin the wires. Tinned wire does not hold its
shape and comes loose over time.
2. Connect the AC power cord of the power supply unit to a
110 or 220 VAC electrical source.
3. When the transmitter or receiver is getting power, either
directly from the power supply or indirectly through the
remote powering feature (receiver), the front panel LED
lights amber.
