A low-voltage power-on guard prevents the receiver operating if
switched on with a voltage below 4.5 V. Once operating, the re-

MULTIPLEX RX-SYNTH receivers can also be operated in con-
junction with transmitters not exploiting Synthesizer techno-
logy, i.e. those using conventional plug-in crystals. Synthesizer
technology simply provides a modern, convenient, extremely
flexible and highly accurate method of generating a fre-
quency.

All MULTIPLEX RX-SYNTH IPD receivers work on the basis of
the FM / PPM transmission process, which is compatible with
most other makes of RC equipment. This means that mixed
operation with FM/PPM transmitters of other makes is possible
in principle. However, we cannot guarantee that such a sys-
tem will work perfectly, as there are too many possible com-
binations for us to check.
