1.2.4 COMMUNICATOR

Before you operate the Wireless IQ system, you must register each Communicator for use with the base station. The base station will then recognize all Communicators registered to it when their power is on, and will be able to tell the difference between them and other electronic equipment operating on similar frequencies.

Note: In tandem or dual-lane systems there are two base stations, a primary and a

secondary. Communicators must be registered to the primary base station.

A maximum of 15 Communicators can be registered. If a Communicator is replaced, you must register the new one before you use it. When a Communicator is replaced, the old one remains in memory. If the maximum number of 15 (in memory) is exceeded, the Communicator ID display in the base station will show “F” for full. See Figure 5. If this happens, you must clear all current registrations and re-register all

active Communicators. To clear all current registrations, press the “CLEAR ALL REGISTRATION” button and the “RESET” button at the same time. Refer to Figure 5 on page 6. Continue holding the “CLEAR ALL REGISTRATION” button after releasing the “RESET” button, until the clear code “c” (lower case) appears on the

2.2 Battery Charger Setup and Battery Charging

Set up the battery charger and charge the COMMUNICATOR® batteries as follows.

2.2.1 Battery Charger Setup for Use In the United States

 Connect the battery

charger cable to the

16.5VAC power adapter or 24VDC power supply as shown in Figure 9.

 Plug the adapter into an

AC electrical outlet. The red lights on the charger will come on and go off, then the yellow lights will come on and stay on.

Figure 10. 230VAC adapter wiring for battery charger

2.2.2 Battery Charger Setup for Use Outside the United States

To use the battery charger outside the United States, in countries requiring a 230 Volt AC adapter, modify the 230VAC adapter as follows. The 24VDC power supply will work with an input AC voltage of 100-240VAC.

 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 AC adapter.  Cut the connector off the AC adapter cable. Cut the spade lugs off the brown and

blue wires of the battery charger cable and cut the green/yellow ground wire as short as possible. No ground wire will be used. Strip enough of the insulation from the wires of both cables so they can be spliced. Splice the AC adapter cable wires to the brown and blue “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. The red lights will come on and

go off, then the yellow lights will come on and stay on.

2.2.3 Battery Charging

Insert up to four COMMUNICATOR® batteries into the charging ports to be charged while you are installing the other equipment. When they are fully charged, install them in the Communicators. Battery charging time is about 2 hours.

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.

2.3 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 during installation. Read this section carefully before proceeding.

2.3.1 Radio Frequency (RF) Interference

Finding the cause of RF interference is difficult and time-consuming. The following precautions will help you avoid the most common RF interference problems.

 Find the best base station and antenna locations before mounting them.  Solder all joints (including crimp joints) at the speaker location. This is very

important in damp climates

 Be certain all connections are tight.  Avoid leaving 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 and FM interference may cause similar problems but require different corrective action. AM interference may increase or decrease at certain times of day, since AM transmitter power must be reduced in some areas between 5 and 7 PM.

Note the following symptoms carefully to determine the possible cause of interference. Call HME at 1-800-848-4468 if you need help.

AM Interference:

Static or hum may be heard in the headset when the system is active. The AM interference can enter the system through the cables connecting the outside speaker/microphone to the base station. To block the AM signal, first find out if there is an AM station in the area, and find out its operating frequency and transmitter output power. You can then modify the equipment with a network of inductors and capacitors that will trap the AM signal where it enters 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 interference can enter the system 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. You may need to move the base station.

FM Interference:

FM interference may cause cracks, pops and other noises to be heard in the headset when the Communicator is transmitting on either channel A or B, or when the system is active.

In the event of an electrical power outage — such as from a lightning storm or power generator failure, if you experience problems with your HME equipment after the electricity comes on again, unplug the equipment and wait 15 seconds, then plug it back in.

2.3.2 Electrical Interference

Electrical faults in appliances and other electrical equipment can cause interference such as 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 the electrical system can be repaired.

Improper Earth Grounds:

Improper earth grounds in the building can cause random buzzing and zip sounds in the headset when operating in either channel A or B. Placing a surge protector between the base station AC adapter and the electrical outlet can eliminate the problem.

Things to consider before and during base station installation

 The base station should be located where, if you stand with your back to the wall, you

can see most of the work area where the Communicators will be used.

 The number of walls between the base station and where the Communicators will be

used should be minimized.

 Sheets of stainless steel on the walls may shield or reflect radio signals.  Outside coverage may be needed for Speed Team operation.  Large windows will allow the signal to pass through and can improve outside coverage.  The antenna coverage area can be extended with the Remote Antenna Kit.  If a system is being replaced, it may not be desirable to use the same mounting location

for the base station as used before, but it may be required it in some cases.

3. EQUIPMENT INSTALLATION

These instructions are for installation of standard Wireless IQ equipment and most commonly used optional equipment. Specific instructions may also be enclosed with optional equipment.

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.

3.1 Base Station Installation

A typical drive thru QSR building is set up as shown in Figure 11. The numbers in Figure 11 refer to the location numbers in the following instructions. This drawing is similar to most store layouts. The base station is typically mounted at location #1. This is also where old equipment is usually found. The order taker is usually at location #2 in a high volume store. The order taker Communicator signal from location #2 must penetrate two walls to reach the base at location #1. Communicator signals from the kitchen must only penetrate one wall to reach the base at location #1. If there are large pieces of equipment in the kitchen or speed team operation is needed outside at location #6, location #1 may be a poor choice for mounting the base. For speed team operations, the signal would have to penetrate three walls and get by the kitchen equipment to reach the base at location #1. Coverage in the store around location #7 and outside

at location #6 may be poor. Don’t forget to check for a basement. Communicator

signals from basements may not reach the base at location #1.

If outside coverage is not needed, mounting the base at locations #3, #4 or #5 is best. Communicator signals from most work areas would thereby require no wall penetration. Other work and seating areas may require signals to penetrate one wall. In this case, the remote antenna kit can be used. The antenna may not need to be mounted very far from the base station unless a large piece of equipment causes a dead spot.

The Wireless IQ base uses two antennas to avoid multi-path dropouts. Both antennas transmit and receive signals. The antenna coverage area can be improved by mounting one antenna away from the base. The base will select the antenna that gives the best signal to a particular COMMUNICATOR® location.

Figure 12. Typical tandem and dual drive-thru layouts

If outside coverage is required for speed team coverage, mount the base as close as possible to the wall that faces the desired coverage area. In this case, mounting the base at location #5 to cover location #6 will minimize wall penetrations. Stores with a large window near the base will have better outside coverage if the base is facing the windows. If there are large windows along the wall next to location #6 outside coverage will be enhanced. Also consider in-store coverage. If the base is located in the best location for inside and outside coverage, but the coverage outside is still spotty then the antenna extension cable needs to be run outside the store. In this case, hanging the antenna under an eve next to the desired area will cover that side of the store very well. Another approach is to go up through the roof and have the antenna overlook the desired side area. This approach overcomes obstacles, like walls, that may shadow the signal when the antenna is at a lower height.

Discuss the location of the base station with the store owner or manager. It should be mounted less than 10 feet (3 meters) from an available electrical outlet, and away from grease and large metal objects. Also, the base transmitter antenna(s) must be installed where they will be at least 7.87 inches (20 cm) from all persons, and will not be near any other antenna or transmitter. The remote antenna kit should be used to extend the coverage area if needed. See section 3.1.3.

Tandem or Dual Drive-Thru Base Stations

For tandem or dual drive-thrus, two base stations (primary and secondary) will be installed. They must not be more than 20 feet (6 meters) apart. Cables must be pulled and routed to connect the primary base station to the secondary base station as shown in the wiring diagrams on pages 43 – 50. A vehicle detector and an outside speaker and microphone will be installed for each order point, and cables pulled as described in sections 3.2 and 3.3.

3.1.1 Walk Test for Best Transmission/Reception

You must do a walk test before permanently mounting the base station, with the base station at various locations until the best possible transmission/reception is found. Check transmission and reception around the area where the COMMUNICATOR®s will be used, with two people using Communicators (with fully charged batteries) pressing button B to communicate with each other. Also, walk past the menu board to test reception when using speed-team operation.

If you need to extend the antenna coverage area, remove power from the base station and install the Remote Antenna Kit as described in section 3.1.3, but do not permanently mount the antenna. Return power to the base station and place the antenna in the area where improved performance is needed. Repeat the walk test as described above, moving the antenna around the area while communicating to determine where the antenna improves transmission and reception most.

Figure 13. Open base station showing four screw holes

3.1.2 Mount Base Station on Wall

When you have found the best location for transmission and reception, unplug the AC power and mount the base station and antenna as follows.

 Hold the base station against the wall at the desired

mounting location, with its door open, and mark the wall through the four screw holes on the back of the cabinet, shown in Figure 13.

 Set the base station down and drill four

(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, leaving

the screw heads 1/8 inch (3.2 mm) away from the wall.

 Mount the base station on the wall by placing the four

screw holes in the back of the base station over the four screws, and sliding the base station downward.

 Connect the base station power adapter cable to the

adapter as you did for the battery charger, as shown in Figure 9, page 9. For use outside the United States, see 230VAC adapter connections shown in Figure 10, page 10.

 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 base station.

/16 inch

3.1.3 Install Remote Antenna Kit (if needed)

The remote antenna kit allows one of the antennas to be mounted up to 30 feet (9.14 meters) from the base station for improved coverage. With the extension cable and mounting bracket, an antenna can be mounted inside a window or outside to extend coverage for speed team operation. Install the remote antenna kit as follows.

 Lay out the enclosed 30 foot (9.14 meter) antenna cable, with its female connector

near the base station and its male connector at the proposed area where the antenna will be mounted. Bend and align the cable to the desired position.

 Remove electrical power from the base station.  Remove (unscrew) the antenna from the top of the base station.  Screw the female antenna cable connector onto the base station antenna connector

where the antenna was removed.

Note: To minimize stress on the connector, bend the cable as required to line it up

with the base station antenna connector before connecting it.

 Screw the antenna onto the male connector at the other end of the antenna cable.  Hold the enclosed antenna mounting bracket against the wall at the desired

mounting location and mark the wall through the two screw holes in the bracket. It may be necessary to mount the antenna high enough to avoid a safety hazard or possible damage to the antenna.

 Remove the bracket from the wall and drill two

at the marked spots.

 Insert the enclosed screw anchors into the holes.  Place the enclosed screws through the holes in the bracket and screw them into the

two screw anchors to secure the bracket to the wall.

Note: To minimize stress on the bracket, bend the cable to line it up with the bracket

before connecting it.

 Replace the antenna on the cable connector mounted on the wall.

Note: The best transmission and reception may be achieved with the antenna

perpendicular to the wall. However, if it is a safety hazard or is likely to be bumped and damaged in that position, it may be necessary for the antenna to be parallel to the wall.

 Return electrical power to the base station and resume normal operation.

3.2 Cable Pulling

CAUTION: If you do not use the HME audio cable, be sure the speaker/microphone

wires you use 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 audio cable has four color-coded, insulated wires and a bare shield (drain) wire. It can be used to connect any component to the base station. Pull the cables (two for full-duplex, one for half-duplex) through the conduit from the speaker post or menu board into the building as follows. For dual drive-thru installations, repeat the following steps to route shielded cable from inside the building to the speaker post or menu board in each lane. For tandem drive-thru installations, repeat the following steps to route shielded cable from inside the building to the speaker post or menu board at each order point.

 Run fish tape from inside the building, through the conduit to the speaker post or

menu board.

 Go outside. If you are pulling more than one cable, mark the cables and spools

for identification. Fasten each cable to the fish tape where it comes out of the

conduit, and go back inside the building.

 Pull the fish tape and cable through the conduit into the building. Disconnect the

cable from the fish tape and pull enough of it in to reach the base station.

 Go outside again 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 about 3 feet (915 mm) of slack. If more than one cable have

been pulled, mark the ends of the cables again for identification.

 Remove about 2 inches (50 mm) of the outer insulation from the end of each cable.

Strip about ½ inch (12 mm) of insulation from each of the four wires in the cable.

 Route all the cables together to the base station, through walls and over ceiling

panels if possible. Cut off any slack cable so no coils of excess cable are left in the ceiling or elsewhere.

3.3 Outside Speaker and Microphone Installation

and Cable Connections

This section describes standard, full-duplex installations, using a DM3 microphone and SP2500LP Low-Profile Speaker. Installation requirements may vary. In duallane or tandem systems, speakers and microphones must be installed for each lane or order point. Refer to the wiring diagrams on pages 43 – 50.

Note: For half-duplex installations, the SP2000A Speaker/Microphone Unit is used.

See Section 3.4, page 20 for installation of the SP2000A.

In full-duplex systems the standard microphone and speaker provide the best performance. However, in some cases the DM1 Microphone may be used. For DM1 installation, refer to the instructions enclosed with the unit. For either the DM1 or DM3, refer to the appropriate wiring diagram on pages 43 – 50.

Mount the microphone first, against the speaker grill in the speaker post or menu board. Positioned it where the customer will speak directly into it. The speaker can then be installed anywhere around the microphone, as long as they are at least 2 feet (610 mm) apart, center-to-center, to avoid audio feedback.

Note: Try the system with the speaker at various locations around the microphone

before permanently mounting it. If feedback occurs, move around until the feedback disappears. If possible, park a vehicle in front of the outside microphone to simulate echo conditions that may also cause feedback.

3.3.1 Microphone Installation

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 below and refer to Figure 16. Installation in a menu board will be similar, within the menu-board speaker compartment.

 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 audio cable (new or

existing) 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 the best performance, mount the

microphone flush and tight against the foam windscreen, behind the speaker grill. Pack the

remaining pieces of foam around the top, bottom and back of the microphone unit, so it will be held 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! In the speaker post or menu board, fill all the holes and openings in

the panel that separates 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.

Use a flat-blade screwdriver, or similar tool, to open the SP2500LP speaker box by prying the rear panel off the box at the four points shown in Figure 17, and remove it.

Note: Mount the speaker

inside the speaker post or menu board if possible. It 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 18. 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 the screw holes on the panel into the speaker post or menu board as shown in Figure 19.

 Route the cable from the back of the speaker

through the wire hole in the rear panel of the speaker box, into the speaker post. Close the box by pressing it 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 20. Do not connect the drain wire. Solder the connection and cover it with a crimp cap insulator.

IMPORTANT! For full-duplex systems, use

separate cables for speaker and microphone, or feedback may occur.

Optional SP2000A Speaker/Microphone Installation

Note: The installation described below is for typical mounting of the SP2000A directly

against the inside of the speaker grill. If it needs to be mounted at an angle, or at a distance from the speaker grill, its base can be bolted to a horizontal surface.

Installation

 Drill four inch (3.2 mm) pilot holes at the

spots shown on Figure 21 A, in the flange of the SP2000A.

 Find the enclosed SP2000A mounting template.

Hold the template centered against the outside of the speaker grill on the speaker post or menu board. With a pencil or other sharp object, mark the speaker grill through the four drill-hole targets on the template. Drill a 3/16

inch (4.8 mm) hole at each of the marked spots.

 Hold the SP2000A flush against the inside of

the speaker grill, with the four pilot holes on its flange directly over the four holes drilled through the grill speaker. From the outside of the speaker grill, drill the four enclosed selftapping screws through the drilled holes in the speaker grill and through the SP2000A flange at each pilot hole, as shown in Figure 21 B.

Cable Connections

CAUTION: Never run high-voltage cables in the same conduit with audio or

loop cables.

 Connect the red wire from the appropriate cable to the white SP2000A wire, and the

black cable wire to the black SP2000A wire as shown in Figure 22. Do not connect the drain wire.

 Solder the connection and cover it with electrical tape. Solder all splices.

3.5 Optional External Vehicle Detector Installation

 If an external type vehicle detector will be used, install it according to its own

installation instructions. Connect it to the base station according to the appropriate wiring diagram on pages 43 – 50. Note that the connections are different for internal and external vehicle detectors.

 Route a cable from the external vehicle detector output to the J30 connector on the

audio board in the Wireless IQ base station.

 Remove 4 inches (100 mm) of outer insulation from the end of the cable at the base

station, and strip about 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 43 – 50. Be certain the wires are fully inserted into each connector plug to prevent shorting the wires.

3.6 Optional HME Vehicle Detector Board (VDB)

Installation

To install an HME VDB in the base station, follow the instructions below.

Note: In tandem systems, there will be a VDB in the primary base station for Order

Point #1, and a VDB in the secondary base station for Order Point #2.

 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, in the position shown on the respective wiring diagram on pages 43 – 50. 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 on pages 43 – 50.

 Route a cable from the underground loop to the TB1 terminal block on the Vehicle

Detector Board.

 Close the cover on the base station, and lock it by pushing until it latches.

Figure 23. External message repeater connections

3.7 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.

4. EQUIPMENT SETUP

4.1 Internal Message Repeater Setup

Locate and set the “Red Message” and “Green Message” slide switches and the “Red Message Control” and “Green Message Control” DIP switches on the front panel of the base station. Refer to section 6.9 for “Red Message Control” and “Green Message Control” switch functions and message recording instructions.

If a System 30 Timer is installed with the Wireless IQ, the timer alert output can be used to trigger tones in the headset or a message to be played by the message

repeater. Set “Red Message Control” and/or “Green Message Control” #5 switch to

ON for an alert message, which will be heard through outside speakers and/or headsets selected with the #2, 3 and 4 switches only in headsets, or OFF for an alert tone to be heard only in headsets. If Wireless IQ message repeater will not be triggered by an alert signal, set both “Red Message Control” and “Green Message Control” #5 switches to OFF so the message repeater input will be triggered only by vehicle detector signals.

4.2 Early Warning Setup

An extra vehicle detector can be used with the Wireless IQ to give a pre-warning signal when a vehicle enters the drive-thru area. To set up a pre-warning signal, first install the extra vehicle detector at the desired detection point then connect its cable. If an external vehicle detector is used, connect its cable to connector J9, positions 1 and 2 on the base station audio circuit board. If an internal Vehicle Detector Board is used, connect P1 on the VDB to J15 on the Audio Circuit Board. Also on the Audio Circuit Board, wire the J25 connector, positions 8 and 9 to the J9 connector, positions 1 and 2 respectively.

4.3 Dual-Lane Setup

To set up the Wireless IQ system for dual-lane operation, place K1 DIP switch #1 on

the base station transceiver board in the ON position, then press the “Reset” button.

Refer to Figure 26 on page 35 and Figure 28 on page 37.

Set the “Green Message Control” DIP switch #8 to the ON position in the Secondary Base only. The Primary Base must be wired to Lane 1, the Secondary Base to Lane 2.

4.4 Split-B Audio Setup

Split-B audio is used in dual-lane operations to limit audio transmission from Lane 1 COMMUNICATOR®s to be heard only by other Lane 1 Communicator operators, and transmission from Lane 2 Communicators to be heard only by other Lane 2 Communicator operators. When the Split-B audio feature is not used, B audio transmission from either lane is heard by all Communicator operators in both lanes.

To set up the Wireless IQ system for split-B audio operation, on the base station transceiver board, place the K1 DIP switch #2 in the ON position, then press the “Reset” button. Refer to Figure 26 on page 35 and Figure 28 on page 37.

4.5 Auto-Hands-Free Setup

Auto-Hands-Free operation is explained on pages 27 – 30. To set up the Wireless IQ system for auto-hands-free operation, on the base station transceiver board, place the K1 DIP switch #3 in the ON position, then press the “Reset” button. Refer to Figure 26 on page 35 and Figure 28 on page 37.

5.1 Noise Reduction Adjustment

When the ClearSound feature is turned on, it provides four levels of noise reduction. It can be adjusted for the best balance of noise reduction and voice quality, considering the store’s environment.

 Locate the S13 switch near the center of the base station audio circuit board. Refer

to Figure 28 on page 37.

 To turn the ClearSound noise reduction feature on, place the S13 switch position 2 ON.

S13 – 1 = VAA ON/OFF S13 – 2 = ClearSound ON/OFF

Note: Factory default settings for S13-3 and S13-4 are shown in bold.

5.2 VAA (Voice Activated Attenuation) Adjustment

The VAA circuit reduces the level of the order taker’s outbound audio that is picked up by the outside microphone and sent back to be heard in the order taker’s headset. This is sometimes referred to as “external loop around” or “echo.”

Note: Misalignment of the VAA circuit can result in complaints of echo, feedback or

fluctuating inbound audio levels.

To activate the circuit, S13 switch #1 (See Figure 28, page 37) must be ON. The factory default setting is ON.

VAA Threshold Level:

This is the volume level of the order taker’s voice required to activate the VAA circuit. During normal operation, the inbound audio level should be reduced when the order taker speaks to the customer, and should recover when the order taker stops speaking. If speaking to the customer does not reduce the inbound level, turn the VAA Level control on the front panel (See Figure 2, page 2) clockwise until the inbound audio is reduced while speaking to the customer. If the inbound is reduced anytime the outbound channel is open, regardless if the order taker is speaking or not, turn the VAA Level control counterclockwise, so the inbound is reduced only when the order taker is speaking.

VAA Attenuation Level:

This is the amount the inbound volume level is reduced when the order taker speaks to the customer. The attenuation level is factory set at 15dB, and should not require adjustment. If the order taker cannot hear the inbound audio at all while speaking, the attenuation level may be adjusted. To increase the inbound level while the order taker is speaking, turn R348 (See Figure 26, page 35) counterclockwise. To reduce the inbound level while the order taker is speaking, turn R348 clockwise. For assistance, call HME at 1-800-848-4468.

6. WIRELESS IQ OPERATION

The COM6000BP can be operated in Hands-Free (HF), Auto-Hands-Free (AHF) or Push-To-Talk (PTT) modes. If your store does not have HF capability, the Wireless IQ should be operated in the PTT mode, according to the instructions on the following pages for single-lane or dual-lane stores.

A full-duplex system supports HF, AHF and PTT operation. Communication can be transmitted and received at the same time, as in a normal telephone conversation. In the AHF mode, transmission and reception are activated automatically when a customer drives into the drive-thru lane. In the HF mode, transmission and reception are activated by touching and releasing one of the A buttons on the Communicator. In the PTT mode, one of the A buttons on the Communicator must be held while the operator is talking to the customer. A half-duplex system only supports the PTT mode. One of the A buttons on the Communicator must be held

while the operator speaks to the customer. The customer’s voice will not be heard

while the operator is transmitting.

In single lane operations, when a customer arrives in the drive-thru lane, you will hear a single beep in the headset.

In dual-lane operations, when a customer arrives in the drive-thru lane you are connected to you will hear a single beep in the headset; when a customer arrives in the other lane, you will hear a double beep.

In dual-lane operation, if you are communicating with a customer in one lane when another customer arrives in the other lane, you will hear a higher pitch double beep in your headset. When the customer leaves the speaker post in the lane you are connected to, the same high pitch double beep will repeat in your headset every four seconds until you touch the A1 or A2 button to communicate with the customer in the other lane.

Note: In dual-lane operations, if you have a Mode Switch and it is in the

“DEDICATED” position, you will only hear single beeps in your headset when customers arrive in the lane you are operating.
