IMPORTANT NOTICE: The RSA-M2 adapter was
developed for use with the original Motorola Radius series of two-way
radios (mid 1980's). It will not work with newer radios that have
programmable features. Confirm compatibility with your recorder and
radio prior to purchase. If an adapter is needed for recording
your radio, see: RSA-M3,
RSA-M4, and RSA-U5.
RSA-M2 is used to provide a simple and inexpensive method of
connecting voice logging recorders to certain Motorola two-way radios. It
only works with older Motorola radios that have an eight position modular
microphone jack with receive audio present at all times. It combines receive and transmit audio at levels
matched to the line input of voice logging recorders. It also
provides transformer isolation and RF bypass. For
newer Motorola radios that do not have constant receive audio on the
microphone jack, use either the RSA-M3 or
RSA-M2 is supplied with cables and connectors which have been wired
to meet most standard applications. It can be customized to meet
unusual requirements. Consult your place of purchase if cables are
required with non-standard lengths, connections, or circuitry.
1. Unplug the microphone cord from your radio set and plug it into
the jack on the RSA-M2 adapter.
2. Plug the short black cable from the RSA-M2 into the microphone
jack on your radio. Your radio should now function normally as you
have simply connected a short extension into its microphone cord.
3. The RSA-M2 can now be connected to your recorder. Its output is
an 18 foot long cable with RJ-11 telephone style plug on the end.
Simply plug this cable into the audio input jack on your logging
4. Locate a convenient spot on your radio to mount the RSA-M2.
Ensure that there is enough slack in the cables so that they can be
easily un-plugged, if required, and that it will not interfere with
the operation of the radio. Use the double stick foam pad and cable
ties which are included with each RSA-M2 to attach it to your radio.
IN CASE OF DIFFICULTY If
the unit fails to work properly, recheck all connections and test
your recorder to see that it is operating properly. Make sure that
the microphone is only active when transmitting, otherwise you could
record room sounds between transmissions (set radio jumpers, or
program for switched transmit audio). Assistance is available from
your place of purchase, or directly from Omnicron Electronics at the
