Dm1 And Foam Inserts Shown In Typical Spp2 Speaker Post Installation - HME Wireless 6000 Installation Instructions Manual

•
Remove the rubber plug from the back
of the DM1 microphone unit, and locate
the POT inside the hole. Turn the POT
approximately ¾ of the way clockwise,
then replace the rubber plug.
•
Place the enclosed thin piece of foam
against the inside of the metal grill.
•
Place the DM1 Microphone into the
holes on the large and small pieces of
foam with holes, in the positions shown
in Figures E-1 and E-2.
•
Place the DM1 in the two pieces of foam
into the upper compartment of the
speaker post, against the thin piece of
foam already in place.
•
Route the DM1 cable down through the
hole in the shelf as shown in Figure E-2.
•
Place the remaining piece of foam (with
no hole in it) against the other foam in
the upper compartment of the SPP2
speaker post.
•
Splice the DM1 cable wires to the audio
cable wires according to the color
codes shown in the appropriate wiring diagram on pages A-15 and A-16.
NOTE: In retrofit installations, splice the DM1 cable wires to the audio cable wires that were
disconnected from the removed speaker, according to the color codes shown in the appropriate
wiring diagram on pages A-15 and A-16.
•
Close the speaker post, replacing all screws that were removed from the back cover.
To install the DM1 Microphone on top of a speaker post, mount the DM1 as follows.
•
Disconnect the microphone cable from the existing SP2000A Microphone Unit or SP2000D
Speaker/Microphone in the speaker post.
•
Determine the best location for mounting the DM1 Microphone on top of the speaker post. For
best performance, it should be 42 to 46 inches (1.07 to 1.17 meters) above the drive-thru lane.
•
Drill a 3 / inch (4.76 mm) hole through the selected mounting surface and center the enclosed
16
rubber gasket over the hole, with the two screw holes in the gasket to the front and rear of the
position the microphone will face as shown in Figure E-3. Mark the mounting surface through
the two screw holes.
•
Using a / inch (2.54 mm) drill bit (approximate), drill a pilot hole through the mounting surface
1
10
at each of the marked spots.
•
Center the rubber gasket over the three holes and place the microphone mounting bracket over
the gasket. Place one of the enclosed lock washers and self-tapping screws through the screw
slot at the front of the bracket and the screw hole in the gasket below it as shown in Figure E-3.
Using a high-speed drill, drill the screw through the mounting surface to secure the bracket in
place. Do not over tighten the screw, or the metal bracket could be damaged. Secure the rear
of the bracket in place with the remaining washer and screw in the same manner.
•
Route the 6 foot (152 mm) DM1 Microphone cable all the way through the hole in the mounting
bracket strain relief as shown in Figure E-4.
