-VOR : 108 to 117.95 MHz Channel width : 50 KHz Between 108 and 112 MHz, the VOR frequencies are the ones in which the figure corresponding to the tenths of MHz is even
(e.f. 108.00, 108.05, 108.20... 111.85).
All the frequencies starting from and including 112 MHz, which
end in 50 KHz, are VOR frequencies.
Only the frequencies assigned to the VOR system can be
displayed when VOR is selected.
Course : 0 to 359..
-ILS : 108 to 111.95 MHz Channel width : 50 KHz. The frequencies dedicated to the ILS are the ones in which the figure corresponding to the tenths of MHz is odd (e.f. 108.10, 108.15, 108.30... 111.95). Only the frequencies assigned to the ILS can be displayed when ILS is selected. Course : 0 to 359..

Data transmission and reception The RMP transmits and receives data in compliance with low speed ARINC 429 standards (between 12.5 and 14 kbits/s). The radio-communication and the radio-navigation equipment receives the frequency and course data through words having a structure and a refresh rate defined in the ARINC characteristics related to these systems.

Light and display test This test is initiated when you set the three-position INT LT/ANN LT switch on the overhead panel 25VU in the cockpit to TEST (Ref. 33-10). During the test:
-The displays show 8s on the RMP
-All the selection feed back lights come on.
During the test, the RMP does not take into account any selection
made on its front face. It transmits the data corresponding to
its configuration at the beginning of the test.
(e)
Micro power interruption and power supply cut-off Any micro power interruption less than 200 ms has no influence on the RMP. In the event of power supply cut-off, the RMP memorizes the context. Consequently, the last configuration selected can be restored when the power supply becomes available again.

The RMPs control the frequencies of the HF and VHF transceivers.

-Selection of the transceiver is accompanied by a selection feedback and the frequencies which have been previously selected and preset appear in the ACTIVE and STBY/CRS display windows respectively.
-Only the preset frequency can be modified by means of the dual selector knob.
-When the preset frequency corresponds to the desired value, you press the transfer pushbutton to render it active. The displayed values are then changed over and the RMP modifies its output data accordingly.
2 SEL indicator light
_ It is possible to control the operating frequency of any transceiver through one RMP. Nevertheless each RMP is more particularly allocated to one or several systems: If 3 RMPs are installed:
-
The RMP1 is associated with the VHF1 transceiver
-
The RMP2 is associated with the VHF2 transceiver
-
The RMP3 is associated with the VHF3(*), HF1(*) and HF2(*) transceivers. (* = if installed)
Each time the system operates in a different configuration (cross selection), the SEL indicator lights on the two RMPs concerned come on (e.g. when the VHF2 transceiver is selected on the RMP1, the SEL indicator lights on the RMP1 and the RMP2 come on). In certain configurations, the SEL indicator lights on the three RMPs are on (e.g. selection of the VHF2 transceiver on the RMP1 and selection of the VHF1 transceiver on the RMP3).
