13 REMOTE MIC OPERATION

When the Remote MIC is connected to the FM-4000, most VHF, DSC, setup
menus and PA modes can be remotely operated. The Remote MIC is supplied
with 23 feet (7 m) of routing cable and can be extended up to 70 feet (21 m)
using three 23-foot extension cables model CT-100. The Intercom feature can
be used between the Remote MIC and the transceiver. In addition, speaker
wires are supplied at the panel mount of the routing cable for external speak-
ers to be connected in noisy environments.
