INSTALLING AN LED AS A PANEL LOCATOR LIGHT
If you wish an LED can be installed between the two front RJ-12
connectors on the panel to serve as a panel locator light. We
recommend using a T1 sized (.100 inch diameter) LED. Solder
the LED to the bottom of the PC board. Leave enough lead
length to bend the LED over and fit it through the hole in the
front panel. You will also need to solder a 1K ¼ watt resistor in
the two holes marked “1K”.
