a qualified Radio Technician.
23. If you are use a radio-specific interface cable, follow the directions included
with the interface cable, then proceed with step 27 in this Installation Proce-
dure.
If you are unsure if your Interface Cable is the proper one, or if you want to
know if Firecom manufactures a Radio-Specific Interface Cable for your
radio(s), contact your local Firecom Dealer.
24. Plug the 9-Pin plug on the end of the supplied MR-0X Mobile Radio Interface
Cable into the desired Radio Interface Jack on the rear of the intercom (Figure

Tighten the 2 screws on the plug of the MR-0X. If these screws are not
tightened, the 9-pin plug may vibrate loose and cause problems with trans-
mission, receptions or other radio problems.
25. Using the information in Figure 17, connect the wires on the MR-0X Mobile
Radio Interface Cable to the appropriate places on the 2-way radio.
26. If the intercom is a 3020 or a 3025, repeat steps 23 to 25 for the second radio.
