There are four configuration jumpers on the AUX board. Jumper JP1 is intended for a
change of the board addressing and is not used at present. The field of jumpers JP3 helps you
redirect the COM2 interface for BOOT program loading. The jumper field JP4 is used for setting
the AUX interface to correspond with the microtelephone or headphone configuration.
Connector K1 is intended for servicing purposes only and may not be used. By default, jumpers
JP1 and JP2 are disconnected, jumper JP3 is connected as shown in Fig. JP3a and jumper JP4
