E Installation
The optional HM-127 can be connected to the transceiver di-
rectly, as well as via the supplied connection cable for longer
distance remote operation. The connector of the connection
cable can be installed into a cabinet, wall, etc., as a built-in
plug.
For longer distance remote operation, the optional extension
cable, OPC-999 (6 m; 20 ft/Connecting between transceiver
and the connection cable.), is available, and up to 2 OPC-999
can be added.
M Insert the supplied cable into the external microphone jack
and tighten the cable nut as shown below.
&copy; To use the supplied cable as a wall socket, follow the fol-
lowing steps.
(3) Using the mounting base, carefully mark off the 2 spots
where the cable and screws will be fastened.
@ Drill holes at these marks.
&reg; Install the mounting base using screws as shown below.
