caps or in an explosive atmosphere. Operating the equipment in
these environments is a definite safety hazard.
1.1.2 High Temperatures
Take care when handling a repeater which has been operating recently.
Under extreme operating conditions (+140°F [+60°C] ambient air
temperature) or high duty cycles, the external surfaces of the base station
can reach temperatures of up to +176°F (+80°C).

1.1.4 Proximity to RF Transmissions
To comply with the RF Field Limits for Devices Used by the General
a
Public for (Uncontrolled Environment)
, a safe separation distance of at
least 12 feet (3.6 metres) from the antenna system should be maintained.
This figure is calculated for a typical installation, employing one 50W
base station transmitter. Other configurations, including installations at
multi-transmitter sites, must be installed so that they comply with the
relevant RF exposure standards.

1.2 Equipment Safety
1.2.1 Installation and Servicing Personnel
The equipment should be installed and serviced only by qualified
personnel.
1.2.2 Preventing Damage to the PA
The repeater has been designed to operate safely under a wide range of
antenna loading conditions. Transmitting into a low VSWR will maximize
the power delivered to the antenna.
Notice Do not remove the load from the TB7304 while it is transmitting.
Load transients (switching or removing the load) can damage the PA output
stage. See MBD-00001-xx TB7300 Installation and Operation Manual for
recommendations.
1.2.3 ESD Precautions
Notice 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.
You can obtain further information on antistatic precautions and the
dangers of electrostatic discharge (ESD) from standards such as ANSI/
ESD S20.20-1999 or BS EN 100015-4 1994.

1.3 Environmental Conditions
1.3.1 Operating Temperature Range
The operating temperature range of the equipment is –22°F to +140°F
(–30°C to +60°C) ambient temperature. Ambient temperature is defined as
the temperature of the air at the intake to the cooling fans.
1.3.2 Humidity
The humidity should not exceed 95% relative humidity through the
specified operating temperature range.
1.3.3 Dust and Dirt
For uncontrolled environments, the level of airborne particulates must not
exceed 100µg/m

1.4 Regulatory Information
1.4.1 Distress Frequencies
The 406 to 406.1MHz frequency range is reserved worldwide for use by
Distress Beacons. Do not program transmitters to operate in this frequency
range.
1.4.2 Compliance Standards
This equipment has been tested and approved to various national and
international standards. Refer to the latest issue of the Specifications
Manual for a complete list of these standards.
1.4.3 Unauthorized Modifications
Any modifications you make to this equipment which are not authorized by
Tait may invalidate your compliance authority’s approval to operate the
equipment.
The manufacturer is not responsible for any radio or TV interference
caused by unauthorized modifications to this equipment. Such
modifications could void the user’s authority to operate the equipment.

1.4.4 Health, Safety and Electromagnetic Compatibility in Europe
In the European Community, radio and telecommunications equipment is
regulated by Directive 2014/53/EU. The requirements of this directive
include protection of health and safety of users, as well as electromagnetic
compatibility.
Intended Purpose
of Product
Declaration of
Conformity
This product is a radio transceiver. It is intended for radio communications
in the Private Mobile Radio (PMR) or Public Access Mobile Radio
(PAMR) services, to be used in all member states of the European Union
(EU) and states within the European Economic Area (EEA). This product
can be programmed to transmit on frequencies that are not harmonized
throughout the EU/EEA, and will require a license to operate in each
member state.
You can download the formal Declaration of Conformity from https://
www.taitradio.com/our-resources/compliance#European.
1.5 Device and Network Security
If this radio network equipment is used for mission-critical applications, it
is important to be able to ensure security and continuity of operation. For
IP-network-connected equipment, it is also important to ensure that this
equipment is not a means of compromising other equipment in the network.
All network elements should be physically secured, where possible. This
includes the use of locked cabinets and locked rooms. Seals on connectors
can also provide a visual indication of unauthorized tampering.
Tait recommends that all network and audio connectors should be sealed
with the stick-on type of seal. The seal should reveal if any of the
connectors have been unplugged, or if any unauthorized equipment has
been plugged in.
The seals should be difficult to remove without breaking, and should bridge
between the cable and equipment side (plug and socket) of the connection.
Seals should cover any unused network or audio sockets. This includes the
Ethernet connector on any adaptor front panels, any spare switch ports, and
the console port on the router and switch.
The seals should be difficult to reproduce. A sticker initialed or signed by
the technician should satisfy this.
Seals must be replaced if they need to be disturbed during maintenance.

1Introduction
The Transportable Mobile Repeater (TMR) is a complete transportable
radio solution in a rugged case. It consists of:
■ a TB7300 repackaged into a rugged pelican case with an internal AC
supply
■ an internal 12v SLA battery
■ a charge circuit and switching circuits for external DC supply.
Notice TMR was designed to be waterproof, but do not operate it in
the rain with the lid open.
An N-type antenna connector on the outside of the case enables a sturdy
external antenna connection. An Amphenol screw-lock connector for the
DC input is also located on the outside of the case.
Four LEDs are present to indicate the status of the repeater. Two further
LEDs are located on the outside front of the case to indicate the status of
the battery while charging.

2 Basic Operation
2.1 Battery Select Switch
Warning When shipping and charging the transportable, set the
battery select switch to External DC/Battery Isolate to comply with
safety regulations.
The battery select switch is protected with a raised red surround to avoid
accidental switching on when the lid is closed.
Warning Risk of missing calls! Switching between Internal Bat-
tery and External DC/Battery Isolate will likely cause the transportable to restart!
When the switch is set to Internal Battery, the transportable runs from the
internal battery (or mains supply if connected).
When the switch is set to External DC/Battery Isolate, the internal battery
is disconnected from all circuitry in the transportable. In this situation, all
the circuits in the transportable,including the repeater, can only run from an
external DC supply. When connected to a mains lead, the charger circuitry
is automatically switched on and connected to the internal battery.
2.2 Battery Power
With a fully-charged battery, an operating regime of 10% transmit at 15W,
and 90% standby time will keep the transportable running for approx. 8
hours (with a new battery).
2.3 Battery Charging
Warning Risk of fire! The lid must be open when charging. The
VRLA battery may vent when charged at a current greater than
3A. This does not occur during normal charging.
The transportable will shut itself down when the internal battery voltage
drops too low. When that level of discharge has been reached, it will take
up to 12 hours to recharge the battery using an AC mains connection. When

charging, press the recessed button located at the left of the Charge LED to
turn charging off and on.
A DC input cable is supplied with the transportable for connection to
external DC Supplies between 10 and 36 VDC.
Notice When the transportable is not in use, always switch the battery select switch to External DC/Battery Isolate.

2.5 Antenna
The transportable is a 15W Repeater that requires a remote mounted
antenna with a suitable ground plane. This antenna and internal duplexer
must be tuned to the frequency of the Repeater. The transportable has an Ntype antenna connector.
Caution Risk of harm from RF radiation! While the Repeater is operating (transmitting), you must ensure that there is always a distance of
0.9m between people and the antenna. This is the minimum safe distance.
2.6 Mains Socket Wiring
The repeater is shipped with a Schurter waterproof AC Mains socket this
will need to be wired by an electrician or electrically registered person.
