Cable layout
1. Use the special cable provided with the operation unit to
connect the operation unit with the main unit.
2. Receive input microphone cable layout
•Use a 2-conductor shielded cable with a high shielding effect.
•Splice the cable from the microphone to the terminal block on
the main unit.
•Be sure to splice the cable with the correct polarity.
3. Transmit output speaker cable layout
•Use a cable of Ø0.9 mm (19AWG) specification or more.
•Splice the cable from the speaker to the terminal block of the
main unit.
•A twisted pair cable is suitable for the speaker.
•Be sure to splice the cable with the correct polarity.
