Connection of tape recorder
A tape recorder can be connected for recording of calls. The recorder can be connected either to
jack J3 fig 8-1 or jack J4 fig 8-1. In jack J3 pins a and b and in jack J4 pins 1 and 6 are used for
tape recorder output. The levels are adapted for 150 ohms load impedance. When using a tape
recorder or equivalent LED 6 shall be set to OFF.

Connection of PC-sound board
A PC sound board or equivalent can be connected to jack J3 fig 8-1. When connecting a “sound
board” two different modes can be selected. For easy connection of the “sound board” the
enclosed cable, RPM 130 017/1 can be connected to jack J3 fig 8-1.
The outgoing signal from the option unit, marked --> on the cable, shall be connected to the
input, often called LINE IN, of the “sound board”. If applicable the incoming signal to the option
unit, marked <-- on the cable, shall be connected to the output, often called LINE OUT, of the
“sound board”. See fig 8-3.
Recording mode:
This mode can be used when the “sound board” shall record an ongoing
conversation. This mode is the same as tape recorder mode i.e. LED 6
is set to OFF.
PC/AUDIO mode:
This mode can be used when the “sound board” shall be used for con-
versation. This mode requires the LED 6 to be set to ON.
