pressed firmly. Use your fingertips, not your fingernails, to press the buttons.
a. Power On/Off
• Power On – Press and release the PWR (power) button. A voice message
in the earpiece will say “power on,” and the red power lights next to the A1
and A2 buttons on the Communicator will go on. After a short time, one light
will go off and the other will change to green, indicating the Communicator is
ready to use. The voice message will say “Lane 1 (or 2) ready.” In dual-lane
operations, a green light next to A1 indicates ready on Lane 1, next to A2
indicates ready on Lane 2.
• Power Off – Press and hold the PWR button for approximately two seconds.
A voice message in the earpiece will say “power off,” and the power lights will
go off.
b. Volume Up/Down
• Volume Up Adjustment – Press and release the volume-up Sbutton.
Each time it is pressed, a beep will be heard in the earpiece as the volume
increases one step. When maximum volume is reached, “maximum” will be
heard in the earpiece. If you press and hold the volume-up button, repeating
beeps will be heard as the volume steps up to maximum. “Maximum” will be
heard in the earpiece, and will be repeated until you release the volume-up button.
• Volume Down Adjustment – Press and release the volume-down Tbutton.
Each time it is pressed, a beep will be heard in the earpiece as the volume
decreases one step. When minimum volume is reached, a double beep will
be heard. If you press and hold the volume-down button, repeating beeps will
be heard as the volume steps down to minimum.

4. COMMUNICATOR®Registration
Prior to operation of the Wireless 6000 system, each Communicator must be registered for
use with a specific base station. The base station will then recognize all registered
Communicators when their power is on, differentiating between them and interfering
transmissions from other electronic equipment operating on similar frequencies.
Register each Communicator as follows:
• Be certain all Communicators to be registered are powered off and the base station
power is on.
• Open the base station and press the registration button near the lower-left corner of the
base station circuit board shown in Figure 5.
⎯If no Communicators are powered on, the status light shown in Figure 5 will be blinking
red. If any Communicators are powered on, the status light will be blinking green.
⎯After you press the registration button, the Communicator ID display will show a
small “o” for open.
• Press and hold the Bbutton while pressing and releasing the PWR (power) button to
turn the Communicator on, then release the Bbutton. This will cause the Communicator
to enter the registration mode.
⎯The status light in the base station will be blinking green, and the Communicator ID
display will continue to show a small “o” for open.
⎯The power lights next to the A1 and A2 buttons on the Communicator will be
blinking red then will change to green.
When the registration is successfully completed:
⎯ The green status light in the base station will be on steady and the Communicator
ID display, to the left of the status light, will show the ID number assigned to this
Communicator. ID numbers are assigned sequentially as 0 thru 9, A, b, C, d and E.
⎯ One of the power lights on the Communicator will remain on steady green.
NOTE: A maximum of 15 Communicators can be registered. If a Communicator is
replaced, the new one must be registered, but the old one remains in memory. If the
maximum number of 15 is exceeded, all current registrations must be cleared, and all
active Communicators must be re-registered. To clear all current registrations, press
the “Clear All Registration” button and the “Reset” button simultaneously. Continue
holding the “Clear All Registration” button after releasing the “Reset” button, until the
clear code “c” (lower case) appears on the Communicator ID display. All active
Communicators can then be registered, one at a time.

5. Battery Removal and Replacement
TO CHANGE BATTERIES: When a battery is becoming weak, a voice in the earpiece
will say “Change battery.” When this happens, take the Communicator out of its pouch
and remove its battery by carefully sliding the battery-release latch in the direction of
the arrow shown in Figure 6. Pull up on the end of the battery near the battery-release
latch and lift the battery out of the Communicator, or turn the Communicator over and
catch the battery in your hand.
TO REPLACE BATTERIES: When replacing a battery in the Communicator, place the
end of the battery with the metal contacts into the battery holder on the Communicator,
in the same position as the battery you removed. Press the top of the battery carefully
into the battery holder until it snaps in place under the battery-release latch.

1.2.3 Battery Charger
IMPORTANT: Before installing the system, connect the AC adapter to the battery
charger and plug it into an AC electrical outlet. Place all the COMMUNICATOR®
batteries into it for charging while the system is being installed.
1. Charger Setup
Connect the battery charger cable to the 16.5VAC adapter as shown in Figure 7.
Plug the adapter into an AC electrical outlet and secure it to the outlet with the
grounding screw (if provided). The red lights will come on and go off, then the yellow
lights will come on and stay on.
2. 230 Volt AC Adapter Connections Outside the U.S.A.
• Connect an electrical plug to the wires on the power cable according to color
codes (Brown = live, Blue = neutral, Green with yellow stripes = ground).
• Plug the other end of the power cable into the receptacle on the AC adapter.
• Remove the spade lugs from the brown and blue wires of the battery charger
cable and cut the green/yellow wire as short as possible. No ground wire will be
used. Cut the connector off the AC adapter output cable. Strip enough of the
insulation from the wires of both cables so they can be spliced. Splice the wires
from the AC adapter cable to the “AC” wires of the battery charger cable. Cover
the splice with electrical tape or shrink tubing.
• Plug the electrical plug into an AC electrical outlet.

3. Battery Charging
• Insert battery in one of four charging ports until it clicks in place.
• Battery charging time is approximately 2 hours.
• Yellow light next to each battery port stays on while port is empty.
When battery is in port, yellow light flashing next to battery port indicates
CHARGE PENDING, which means the temperature where the charger is
located is out of the battery’s operating range (32o-104oF, 0o-40oC).
Adjust the room temperature or move the charger to a cooler area.
When battery is in port, yellow light on steady next to battery port means
CHARGE FAILED. Follow diagnostic instructions on side of battery charger.
• Red CHARGING light next to battery port stays on while battery is charging.
• Green READY light next to battery port goes on when battery is fully charged.
• Store fully charged batteries in storage ports.
CAUTION: Do not remove batteries from the charger until the green READY
light is lit, or the charger will reset and the charge cycle will begin again.

2.1 INTERFERENCE PREVENTION
CAUTION: Interference may occur if the audio system is not properly installed.
The following types of interference could occur if precautions are not taken in installation of
the system. Read this section carefully before proceeding with the installation.
2.1.1 Radio Frequency (RF) Interference
Resolving the cause of RF interference is difficult and time-consuming. The following
precautions will help avoid the most common RF interference problems.
• Find the best base station/antenna location before mounting it permanently.
• Solder all joints (including crimp joints) at the speaker location. This is especially
important in damp climates
• Be certain all joints and connections are tight.
• Avoid leaving long lengths of unshielded wire anywhere in the audio system.
• Ground the shield of the outgoing speaker cable. In severe cases of interference,
grounding the shield at the speaker may help.
AM broadcast and FM radio frequency interference may cause similar problems but require
different corrective action. AM interference symptoms may appear to be less severe at
certain times of day, since a 50% reduction of transmitter output power at dusk (5-7 PM) is
required in some areas for AM radio stations rated at or above 100kW. Note the following
symptoms carefully to determine the possible cause of interference. Call HME at
1-800-848-4468 if assistance is required.
AM Interference:
Static or hum may be heard in the headset when the system is active. The point of entry of
the AM interference is at the outside speaker/microphone via the cables connected to the
base station. In order to block out the AM signal, first locate and identify any AM station in
the area, and find out its operating frequency and transmitter output power. The system can
then be modified with a network of inductors and capacitors that will trap the undesirable
AM signal at the point of entry into the system. Static, hum and/or voice may be heard in the
headset when the system is active or when transmitting in either channel A or B. The point
of entry for the interference can be at three different locations: the outside speaker cables,
the COMMUNICATOR®receiver, and the base station transmitter. The AM station frequency
may completely suppress or overpower the audio system’s transmitter signal, depending on
the operating frequency, transmitter tower location and output power of the AM radio station.
It may be necessary to move the base station.
FM Interference:
A common symptom of FM interference is the presence of cracks, pops and other noises in
the Communicator when transmitting on either channel A or B, or when the system is active.
2400MHz Wireless Telephone Interference:
If there is a 2400MHz cordless telephone nearby, interference may occur. However, because
the Wireless 6000 is a frequency-hopping system, this problem is unlikely. If it does occur,
changing frequencies on the telephone may alleviate the problem. If not, move the phone as
far as practical from the base station, or ask the customer to use another type phone.
SECTION 2. SYSTEM INSTALLATION AND SETUP

10
2.1.2 Electrical Interference
The effect of electrical faults in appliances and other electrical equipment can make operation
of a wireless system ineffective in communicating with customers. The most common
symptoms are static, hum, crackling, buzzing and zip sounds in the headset when the system
is active. Interference caused by electrical faults in lighting systems might not be noticed
immediately, since most lighting systems are controlled by a timer or light-sensing device.
Faulty Wiring or Components:
Faulty components or electrical wiring in menu boards or speaker posts can cause symptoms
identical to those caused by AM interference. Remove power to the menu board or speaker
post at the circuit breaker until proper repair of the electrical system can be made.
Improper Earth Grounds:
Improper earth grounds throughout the building can result in random buzzing and zips in
the headset when operating in either channel A or B. Placing a surge protector between the
base station AC adapter and the AC electrical outlet will eliminate the problem in most cases.
2.2 PREPARATION FOR INSTALLATION
Approximately 3 hours is required for installation of the Wireless 6000.
Before installing the system, coordinate the time of installation with the store owner/manager
to minimize disruption of business.
Be certain the site has been properly prepared as follows.
• Electrical power must be connected and available.
• Some type of compatible vehicle detector loop or other vehicle detector system must
already have been installed in the drive-thru lane(s).
2.2.1 Tools Required
• Phillips (cross-point) screwdriver, size #2
• standard (slotted) screwdriver, 1/8 inch (4 mm)
• power drill and drill-bit set
• fish tape, 100 feet (30 meters)
• wire cutter / stripper
• soldering iron
• rosin-core solder
• electrical tape
IMPORTANT: If you haven’t already done so, before proceeding with the installation,
plug the battery charger into an AC electrical outlet and place all COMMUNICATOR®
batteries into it for charging while the other equipment is being installed.

11
2.3 INSTALLATION PROCEDURE
2.3.1 Base Station Installation
Discuss the location of the base station with the store owner or manager. It should be
mounted with the bottom of the cabinet no more than 5 feet (1.52 meters) above the floor,
away from grease and large metal objects. It must be near enough to an available AC
electrical outlet to reach the outlet with the 10 foot (3 meter) AC power adapter cord. It
must be near enough to the pull box to be reached by the cables, which will be pulled into
the building through the outer wall. Also, the antenna(s) used for the base transmitter must be
installed to provide a separation distance of at least 7.87 inches (20 cm) from all persons, and
must not be co-located or operating in conjunction with any other antenna or transmitter.
NOTE: For dual drive-thru installations, follow the instructions below to install two base
stations near each other. The two base stations must not be mounted closer than 3 feet
(.91 meter) from each other. Interconnect the J22 and J26 connectors as shown on pages
25 — 28. Cable pulling and installation of an outside speaker and microphone for each lane
will also be done according to the following instructions.
Walk test transmission and reception with two people using COMMUNICATOR®s (with fully
charged batteries), pressing button Bto communicate with each other around the area
where the Communicators will be used. Also, walk past the menu board to test reception
when using speed-team operation. Continue doing this with the base station in various
locations until the best possible transmission/ reception is found. When you have determined
the best location, unplug the AC adapter and mount the base station on the wall as follows.
• Hold the base station, with its door open, against
the wall at the desired mounting location, and
mark the wall through the four screw holes on
the back of the cabinet as shown in Figure 10.
• Remove the base station from the wall and drill
four 3/16 inch (4.76mm) holes in the wall at the
marked spots.
• Insert the enclosed #6 screw anchors into
the holes.
• Screw the four enclosed screws into the anchors
as shown in Figure 11, leaving the screw heads
approximately 1/8inch (3.18mm) away from the wall.
• Position the four screw holes in the back of the
base station over the four screws, and slide the
base station downward to secure it in place.
• Connect the base station power adapter cable to
the base station’s 16.5VAC adapter as you did for the
battery charger, as shown in Figure 7, page 7. For
use outside the United States, see 230VAC adapter
connections shown in Figure 8, page 7.
• Connect the two wires at the other end of the
cable to J16 on the top-left of the audio circuit
board in the base station. Plug the adapter into
the electrical outlet nearest the desired base
station mounting location. Figure 11.

2.3.2 Cable Pulling
CAUTION: If not using the HME Audio Cable, be certain the speaker/microphone wires
are a twisted pair. For full-duplex installations, the speakers and microphones must
use separate cables or audio feedback will occur.
Never run high-voltage cables in the same conduit with audio or loop cables.
The recommended HME cable contains four color-coded, insulated wires and a bare
shield (drain) wire. This cable can be used to connect any Wireless 6000 component to
the base station.
Pull the cables (two for full-duplex, one for half-duplex) through the underground conduit
from the outside speaker post or menu board into the building as follows.
NOTE: For dual drive-thru installations, repeat the following steps to route cable from
inside the building to the speaker post or menu board in each drive-thru lane.
• Run fish tape from inside the building, through the conduit to the speaker post or menu
board.
• Go outside. If more than one cable are being pulled, mark the cables and spools for
identification. Fasten each cable to the fish tape where it comes out of the conduit,
and return to the customer-service area inside the building.
• Pull the fish tape and cable through the conduit, into the building. As the cable comes
through the conduit, disconnect it from the fish tape and continue pulling enough of it
through the conduit to reach the base station.
• Return to the outside customer-service area, and route the cable from the outside
conduit to the speaker and microphone units in the speaker post or menu board.
• Cut the cable, leaving approximately 3 feet (915 mm) of slack. If more than one cable
have been pulled, mark the ends of the cables again for identification.
• Remove approximately 2 inches (50 mm) of the outer insulation from the end of each
cable. Strip approximately ½ inch (12 mm) of insulation from each of the four wires in
the cable.
• When all cables have been pulled from outside into the building, gather the cables
inside the building and route them together to the base station, through walls and over
ceiling panels if possible.

2.3.3 Outside Speaker and Microphone Installation
and Cable Connections
This section describes standard, full-duplex installations, using the standard microphone
and the SP2500LP Low-Profile Speaker. Specific installation requirements may vary.
Refer to the wiring diagrams on pages 25 — 28 for cable connections.
Although the standard microphone and SP2500LP will provide optimum performance, in
some cases the DM1 Microphone may be used. For DM1 installation instructions, see
Appendix E.
NOTE: For half-duplex installations, see Appendix D for installation of the SP2000A
Speaker/Microphone Unit. The SP2000A is used as the speaker and microphone in
half-duplex installations.
In order to avoid audio feedback, the speaker unit must be mounted at least 2 feet (610 mm)
from the microphone unit. Positioning of the two units is critical.
The microphone unit must be mounted inside the speaker post or menu board, against the
speaker grill. It should be installed first, so it can be positioned where the customer will be
speaking directly into it. The speaker unit can then be installed anywhere around the
microphone unit, as long as they are at least 2 feet (610 mm) apart, center-to-center.
This distance may vary according to specific conditions.
NOTE: Try the system with the speaker unit at various locations before permanently
mounting it. If it is not positioned correctly, feedback may occur. If this happens,
reposition the speaker at other locations around the microphone unit until the feedback
disappears. If possible, park a vehicle in front of the post to simulate echo conditions
that may also cause feedback.
1. Installing the Microphone
Typical microphone installation involves mounting the unit with the enclosed
foam pieces, inside the upper compartment of the speaker post. The foam will fit
many types of speaker posts and menu boards. If the microphone must be mounted
in a small area, compress the foam when installing it and closing the speaker post or
menu board. In larger areas, additional foam (not supplied) must be added.
To install the microphone in a typical speaker post, follow the instructions on page 14
and refer to Figure 13. Installation in a menu board will be similar, within the menu-
board speaker compartment.
Figure 12. Microphone

• Open the speaker post and remove
any existing equipment, foam or
debris. If there is an existing
microphone, remove it and
disconnect the microphone cable
from it.
• Splice the wires of the microphone
cable (new or existing) from the
audio system to the wires of the
cable extending from the microphone
unit, according to the audio system
wiring diagram.
• Place the enclosed foam
windscreen against the inside
of the metal speaker grill.
• Place the front of the microphone
unit flush against the foam
windscreen, centered on the
speaker grill.
• For optimum performance, the microphone must be mounted flush and tight
against the foam windscreen, behind the speaker grill. Pack the remaining
enclosed pieces of foam around the top and bottom of the microphone unit, and in
back of it, so it will be held securely in place against the speaker grill when the
compartment is closed. If required, add extra foam (not supplied) on the sides of
the microphone to fill the enclosure.
• IMPORTANT: Fill all the holes and cavities in the speaker post or menu board,
between the speaker and microphone, with insulating foam sealant (“Great Stuff”
expanding polyurethane foam or equivalent, available at home improvement stores).
CAUTION: Do not use the foam sealant in a wet area, or allow it to come in
contact with water. See can for precautions and safety information.
• Close the speaker post.
2. Installing the SP2500LP Low-Profile Speaker
Use a flat blade screwdriver, or similar tool, to open the SP2500LP speaker by prying
the rear panel away from the speaker box at the four points shown in Figure 14. Remove
the rear panel from the speaker box as shown in Figure 15.
Figure 13.

Keep in mind that the SP2500LP must
be mounted at least 2 feet (610 mm)
from the microphone, center-to-center.
• Hold the rear panel of the
SP2500LP flat against the surface
of the speaker post or menu
board, at the desired mounting
location, as shown in Figure 16.
Use a pencil to mark the speaker
post through the wire hole in the
panel. Remove the panel and set it
aside. Drill a ¼ inch (6 mm) wire
hole at the marked location.
• Hold the rear panel against the
surface, in the same position as
before, and screw the four
enclosed self-tapping screws
through each of the screw holes
on the panel, into the speaker post
or menu board as shown in Figure 17.
• Route the cable from the back of the
speaker through the wire hole in the
rear panel of the speaker assembly,
into the speaker post. Close the
speaker assembly box by pressing it
tightly against the rear panel.
SP2500LP Cable Connections:
• Inside the speaker post or menu
board, connect the green and white
wires of the appropriate cable to the
wires coming from the speaker as
shown in Figure 18. Do not connect
the drain wire. Solder the connection
and cover it with electrical tape or
shrink tubing.
IMPORTANT: For full-duplex systems, use separate cables for speaker and
microphone, or feedback may occur.

2.3.4 Optional External Vehicle Detector Installation
If an external type vehicle detector will be used, install it according to its own installation
instructions. Connect the vehicle detector to the base station according to the appropriate
wiring diagram on pages 25 — 28. Note that the connections are different for internal and
external type vehicle detectors.
• If an internal vehicle detector is used, route a cable from the underground loop to the
TB1 terminal block on the Vehicle Detector Board.
• If an external vehicle detector is used, route a cable from its output to the J30
connector on the audio board in the Wireless 6000 base station.
• Remove 4 inches (100 mm) of outer insulation from the end of the cable at the base
station, and strip approximately ¼ inch (6 mm) of insulation from each of the color
coded wires coming from the cables.
• Connect the color-coded wires to connector J30, pins 3 and 5 for negative vehicle
detection according to the wiring diagrams on pages 25 — 28. Be certain the wires are
fully inserted into each connector plug to prevent shorting the wires.
2.3.5 Optional HME Vehicle Detector Board (VDB) Installation
To install an HME VDB in the base station, follow the instructions below.
• Open the base station by pushing the latches on the front cover and VERY CAREFULLY
guiding the cover downward.
• Carefully position the three holes in the VDB over the three plastic standoffs at the upper
right side, inside the base station as shown in Figure 10. Press on the VDB until the tips
of the three standoffs snap through the holes in the board.
• Connect the cable assembly enclosed with the VDB to the P1 connector on the vehicle
detector board, and the other end to the J6 connector near the upper, right corner of the
switcher board. If there is no switcher board, connect the cable assembly to the P1
connector on the vehicle detector board, and the other end to the J10 connector at the
right end of the audio circuit board as shown in Figures 20 — 23 on pages 25 — 28.
• Close the cover on the base station, and lock it by pushing until it latches.

2.3.6 External Message Repeater Installation
If an external message repeater is used, it must be wired in series with the outside speaker.
It also requires a vehicle-present signal. Connect the message repeater vehicle-present
input to the isolated vehicle detector output on the Audio Circuit Board.
NOTE: No output detect will be generated if the base station power is removed.
