) prior to
installation. Failure to follow these precautions may cause personal injury and/or damage to
the equipment.
1.
Remove the lid of the unit by unscrewing the four corner fixings.
2.
Mark the surface on which the RRM02 unit will be fitted with the fixing hole positions.
The RRM02 unit is approximately 90 mm x 160 mm x 360 mm in size, excluding the glands and
conduit entries, and has the four fixing holes on 110 mm x 340 mm centres (see
Figure 6
).

3.
Prepare the mounting holes appropriately.
4.
Adjust the Radio Microphone Receiver as follows (see
Figure 7
):
a.
Select the correct RF frequency via the internal rotary switch.
b.
The Receiver is supplied with pilot tone detection enabled for secure use with the ASL RPA01
Radio Microphone Transmitters. This configuration will completely block announcements from
Radio Microphone Transmitters that do not provide the required pilot tone (
non-tone locked
transmitters
)
1
.
The pilot tone detection can be disabled via DIP switch 1 on the microphone PCB in order to
allow announcements from non-tone locked transmitters.
c.
Select the squelch level via DIP switches 3 and 4 on the microphone PCB in order to minimise
the interference of in-band signals.
1
Announcements from non-tone locked transmitters are completely blocked with Radio Microphone Receiver modules of Build
Standard (BS) 2B or later. With earlier Build Standards of Radio Microphone Receiver module the audio from non-tone locked
transmitters is muted but they can still make chimes and silent routes. These silent routes can be blocked as detailed in ASL
Technical Note 39; please refer to Application Solutions (Safety and Security) Limited for further details.
