Paper Survey
Use the site survey foxm to begin the evaluation of RF in a binge operation. Diagraming the
hall is an important step to lay out the necessary testing areas. Figure 5 provides a sample
hall on which to base your diagram. If the ball has more than one room, each room will
need to be diagrarned individually Create an architectural diagram of the hall using the
graph paper located in the site survey form.
Note: RF site surveys must be performed or approved by a Field Supervisor.

0 Measure the room(s) in the
' Locate where the master computer is placed. The Base Station Controller (BSC)
needs to be located within a 25 ft. cable length of it.
- Once the location of the BSC is determined, the optimum placement of the trans-
mitters and routing of the CATS cables from the BSC to each transmitter needs to
be determined. Each transmitter can cover a circular area with a radius of about
100 feet (200’ diameter). Use the site survey form to assist in the placement.
- Using the site survey form to create a diagam, cut out four circles representing the
100’ radius of the transmitmrs, Adhere to the rule that each location on the floor
must be able to see at least two transmitters The sample hall in Figure 5 displays
the radiation patterns of each respective transmitter, (The scale of the drawing has
been reduced for this document)
- The transmitters are represented by the small squares down the center line of the
hall Ceiling mounting is highly recommended because it keeps the signal from
being blocked by player's bodies and the height gives the best overall coverage for
each transmitter,
Interference Signals
When walking through the hall with all equipment (computers, etc) turned on and no
active transmitters, only the bottom red LED on the SSM should be illuminated when the
power switch is pressed. Noise or other insignificant signals may cause the second red
LED to flash randomly, If a constant yellow or green illumination is present, the source of
the interfering signal must be determined and considered
Examples of Possible Interferences: t,
~Wireless Gaming Devices -Wireless microphones -Cord.less Phones
—Cell Phones -Wa.lkie Talkies ~Radios
Location and [solution of Interferences:
When walking through the hall and interference is picked up, attempt to locate the item(s)
either visually or by asking persons in the areas If the signal is too strong and cannot be
moved in frequency or eliminated, it may disqualify the hail from using as an RF system.

Coverage
System Installation
Position the standalone batteryApowered transmitters in locations determined by the
paper survey.
The SSM is then used to determine the adequacy of coverage of the transmitter
placement
With the system active at least one green LED should illuminate in all locations
within the circle defined by the paper survey, Remember with one transmitter
only you may see the "dead spots" from location to location as you move
through the area This is normal. The SSM's receiver is calibrated to respond
like those in the TED® and TEDZC’“.
One green LED illuminated is sufficient signal for essentially error free data
transmission. When the entire system is installed it‘s expected for the top green
LEDs to blink during normal system operation, Each transmitter is turned on
sequentially by the BSC. No two transmitters are ever on at the same time.
Consequently, the signal strength indicated by the green LEDs will vary caus-
ing the top LEDs to blink on and off at the scan rate of the system This phe-
nomenon is caused by the SSM picking up transmitters close by (large signal)
and those farther away (small signal),
Lfthe signal strength, as indicated by the SSM, is adequate throughout the hall, the
hall can be considered a good candidate for the RF systemi

Technician Questiq
Q: How long will the battery on the ssM lasts?
A: Quite a long time since it is activated only when the button is pushed and the
button is momentary.
Q: Any special way that the SSM should be held while performing tests?
A: With antenna straight up is best.
Q: Where should the EFT be placed? Is on top of a bingo table close enough when the real
unit will go in the same location just 20 feet higher? Does it need to be exactly where the
other transmitter will go?
A: Without people in the room, just on a table or maybe a 6' step ladder. People
make the biggest difference in signal propagation.
Q: How long should the tech stop in each location to ensure that they are getting a good
signal? How many locations should they check for signal at?
A: They should go to the extremes of the hall (corners) and flien down the center
stopping for 5 to 10 seconds at each location about 20' feet apart. With a single BPT
when they stop they should move the SSM around for the best signal. With one
BPT there will be dead spots during this test.
Q: Can We assume that the hall will be empty when the test is done? Do we care?
A: Only if the EFT is on the ground level and if there are a few bodies around it
probably Won’t be a big deal,
Q: How do you how when the battery is dead on the EFT?
A: There are two LEDs on the EFT, a Green and Red. The Green LED indicates
power and is always on when there is power applied. The Red one blinks at a 1 sec-
ond rate when transmitting (transmission is constant even though the LED blinks).
When the Red LED stops blinking the Green one is dim it is time to change the bat-
tery. A typical 9V alkaline battery has a capacity of about 590 mAH so the BFl"
should easily last at least 1245 hours if left on continuously

Technician Questions
Q: In the “Interference” information, what are some examples of devices that may interfere
(cordless phones, walkie talkies, etc)? Possibly other wireless gaming devices?
A: You hit on two of the biggies Wireless microphones are another potential
source. At the BETA hall we experimented with both a cordless phone and the
Wireless mic and neither caused any problems There is currently no data on other
Wireless gaming devices like the Fortunet system. Some Commercial Power com»
panies use 928 MHz for their SCADA (System Control And Data Acquisition) sys-
tems and communicate with their substations with it. This is a very remote
possibility for interference.
Q: In the “Coverage" information, is there any special way that they need to mount the
EFT when doing the test? Height, location, antenna direction, etc.
A: At the BETA hall, the XMTRs were mounted upside down attached to the ceil-
ing framework. Learning from that experience each XMTR enclosure now has a
small slot cut in the bottom to accommodate a tie wrap mount technique.

Conducting a Site Surv y
Prior to conducting the site survey, the technician should read and be familiar with the information con—
tained in the GameTech RF installation and Support manuali The site survey must be completed prior to
considering a hall for RF and must include the following information:
~ Information on how the site survey was performed.
' Results of site survey.
- Transmitter locations.
' Site survey notes.
For assistance call Customer Support at 1—800-959-1727.
RF site surveys must be performed or approved by a Field Supervisor.
Site Survey Form
The following worksheet is provided for technician use. Please ensure the information is completed in
detail, Several diagrams are provided to diagram the hall to scale. For transmitter radius, use the provided
circles or a protractor to ensure the proper coverage

Getting Started
To provide guidance for conducting an RF site survey, use the following as a guideline.
1~ Contact field supervisor to obtain testing tools as follows:
- Signal Strength Meter (SSM)
- Standalone Battery Powered Transmitter
2' Print the site survey form.
3‘ Walk the hall using the SSM to check for interference with all equipment turned on (comput-
ers etc.) and no active transmitters. If hall passes this step, continue to next step. '
Attention: As a general rule, each RF TED® and/or TEDZCm needs to be able to “see" at least two trans-
mitters to avoid dead spots
‘4 Using the site survey form, measure and diagram the hall.
5‘ Mount BPT (Battery Powered Transmitter) based on hall diagram.
“ If results are positive, hall can be installed with RF (must be approved by Field Supervisor).

Graph paper has been provided on the following pages To complete the diagram(s), draw the hall
to the chosen scale, cut the appropriate circles and place on the drawing where needed (one circle
per transmitter), See the sample diagram below based on a 50’ scale for reference,
(One transmitter = 100 ' radius (200’Diameter))
Note: A protractor can he used in lieu of cutting circles, To use a protractor, place the point at the proposed
transmitter location and using the scale desired, draw a circle 100’ from each side of the transmitter
(100’ radius, 200‘ diameter).
