Connecting an External Speaker to VC70
It may be necessary to install an external speaker in noisy environments.

it to the VC70 External Speaker connector using the adapter cable (PN
25-159552-01).
Installing an External Microphone Mount
The External Microphone mount consists of the following two kits:
• microphone holder with two screws and captive washers
• side mount with two screws and captive washers
1. Attach the microphone holder to the side mount, using two M4x12mm
screws with captive washers. Torque the screws to 8 + 10% kgf-cm (7

NOTE When connecting the adapter cable, the audio is
automatically routed to the external speaker. If the external
speaker is not connected, you will not be able to hear any
audio.
