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.
