Tuning and Configuration
Once the Multitone Paging Interface is fitted, you will need to tune the base station before
operating it. To do this you will need to use the Calibration and Program Application software to
configure your base station to suit the requirements of your radio system. Refer to the Calibration
Application and Program Application documentation for full details on these procedures. The
Calibration and Programming Software will be available from the TaitWorld Support web site.

This section describes how to fit a Multitone Paging Interface into a
TB7100 base station (DC and no duplexer fitted). It also provides some
generalinformationonsafetyprecautionsandMultitonePagingTransmitter
set-up. We recommend that you read the entire chapter before beginning
the fit out.
1.1 Personal Safety
1.1.1 Proximity to RF Transmissions
Donotoperatethetransmitterwhensomeoneisstandingwithin90cm(3ft)
of the antenna. Do not operate the transmitterunless you have checked that
all RF connectors are secure.
1.1.2 High Temperatures
Take care when handling a TB7100 base station which has been operating
recently. Under extreme operating conditions (+60°C [+140°F] ambient
airtemperature)orhighdutycyclestheexternalsurfacesoftheTB7100 base
station can reach temperatures of up to +80°C (+176°F).
1.2 Equipment Safety
1.2.1 ESD Precautions
Important This equipment contains devices which are susceptible to
damage from static charges. You must handle these devices
carefully and according to the procedures described in the
manufacturers’ data books.
We recommend you purchase an antistatic bench kit from a reputable
manufacturer and install and test it according to the manufacturer’s
instructions. Figure 1.1 shows a typical antistatic bench set-up.
Youcanobtainfurtherinformationonantistaticprecautionsandthedangers
of electrostatic discharge (ESD) from standards such as ANSI/ESD
S20.20-1999 or BS EN 100015-4 1994.

1.4 Parts Required
Before beginning the fitting procedure gather the following parts.
1.5 Disassembly and Reassembly
This section describes how to:
■remove and open and close the base station
■remove and fit the modules
General Important Before disassembling the base station, disconnect the base
station from any test equipment or power supply.
Disassemble only as much as necessary to fit the new modules.
Observe the torque settings indicated in the relevant figures.
Important To ensure adequate airflow through the base station, do not
cover thefan intake grill on the front panel.Do not operate
for more than a few minutes with the fan intake covered.

Saving the Base
Station
Configuration
Before replacing a module in the base station, you should decide whether
you need to save its configuration data. If you are unsure whether you have
a record of the configuration, use the Programming Application to read the
base station and save the configuration files before removing any modules.
Once you have replaced the module, you will be able to restore the original
configuration by programming the saved configuration back into the base
station.
1.5.1 Removing the Multitone Paging Transmitter
Important The modules in the Multitone paging transmitter are not
hot-pluggable. It is recommended the tray is removed from
the rack before any modules are removed.
1. Remove the fusee at the rearof the Multitone paging transmitterto
disconnect the Multitone paging transmitter from DC power.
2. Use a Philips #2 screwdriver to disconnect the cables from the DC
power connector f.
3. Disconnect the antenna connectors d.
4. Disconnect any other connectors.
5. Disconnect the ground cable from the ground point c.
6. Use a PZ2 Pozidriv screwdriver to remove the four M6 screws, and
remove the Multitone paging transmitter from the rack.
7. Use a Torx T10 screwdriver to remove from the cover the 15
countersunk screws. Remove the tray cover b.

page 14.
1.5.3 Removing the Receiver Module
1. Disconnect the cables to the RF b, DC power c, system interface
d, and the user interface econnectors.
2. Remove the Rx RF cable, connected to b (219-02978-00 CBL
coax 400Ntype pnl skt BNC) from the rear panel. Place the cable
aside.
3. Fit the blanking panel (303-23055-00 CVR plt A4M955 N conn) to
