The MWx-31 Series is a motorcycle-handlebar-mounted
transmitter for remote PTT control of a portable radio
connected to a Setcom SWE-xx or SWA-xx Liberator
SuperMic.
(several models of SuperMic exist, the actual model
number depends on the portable radio model to be used)
The transmitter requires 12 VDC, supplied through a
fused connection, a 1 Amp fuse is recommended. Red
wire to +12V, Green wire to Ground.
Minimal power is drawn from the motorcycle but it is
recommended that it be supplied from a switched source,
such as the Accessory Lead.
The MWx-31 must be code-matched to the Supermic it is
to be used with. Details for this can be found on page 2 of
these instructions.
Various combinations of TX Unit and PTT switch
mounting brackets are available – the specific model
number indicates the typical motorcycle type the model
will be used on.
A complete system will include an MWx-31 Handlebar TX
Unit and brackets, an SW_-xx SuperMic, and a KE or KA
type of Helmet Kit (model number varies according to the
type of helmet).
Page 3 shows instructions on how to install the PTT
push-button assembly to a bracket.
