3.4 TURNING ON THE RFL 9660
To turn on the RFL 9660, simply place the rocker switch on the RFL 9125 power supply in the ON (up) position.
It will initialize and run through a diagnostic routine; this will take about 90 seconds. When the letters "PL"
appear in the STATUS display, the RFL 9660 is ready for use. "PL" means the RFL 9660 is polling its local and
modem ports, looking for a connection.
