12. Insert the Bend Relief Grommet into the HM-10 so the groove in the grommet is
over the side case of the HM-10 (Figure 11).
13. Replace the bottom plate of the HM-10 and secure with the 2 screws.
14. Mount the HM-10 in place on the apparatus.
15. Route the CA Cables to the rear of the Intercom Unit (or the next Headset
Module in a Daisy-Chain).
16. Attach an RJ-12 Modular Plug to the end of the flat CA Cable (see page 22 for
instructions if necessary).
17. With the "release-tab" on the RJ-12 Modular Plug facing up (Figure 13), insert
the RJ-12 Modular Plug into a modular jack on the rear of the intercom unit
(Figure 13). Make sure that the positions which require radio transmit capabilities
are plugged into the proper jacks.
18. Repeat steps 8 through 17 until all remaining Headset Modules have been
connected with the CA Cable to the Intercom Unit or the next Headset Module
in a Daisy-Chain.
POWER & GROUND CONNECTIONS
Before making the power connections, make sure the apparatus master switch is OFF!
19. Connect the Power Cable Assembly to the rear of the Intercom Unit.
20. Connect the black wire (from pin 1) to the vehicles negative ground.
We suggest connecting the intercom power connections to the apparatus power
busses (preferably, to the same point that the 2-way radio is connected).
21. Connect the red wire (from pin 2) to one end of the supplied in-line fuse holder.
22. Connect the other end of the fuse holder to the vehicles switched +12 VDC.
The 3000C Series Intercom System is installed and ready for connection to the radio.
