Wiring, grounding, and power

Use a copper wire of sufficient size to ensure the voltage across the
transmitter power terminals does not drop below 9 Vdc. Power supply voltage
can be variable, especially under abnormal conditions such as when operating
on battery backup. A minimum of 12 Vdc under normal operating conditions
is recommended. Shielded twisted pair Type A cable is recommended.
