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.
1.1.4 Proximity to RF Transmissions To comply with the RF Field Limits for Devices Used by the General Public for (Uncontrolled Environment)a, 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. a.
Draft 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 ting.
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/m3. 1.
Draft 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 This product is a radio transceiver.
Draft 1 Introduction 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.
Draft 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.
Draft 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. 2.4 LED Indication Details 2.4.
Draft LED 2.5 Indication Details Charge red battery is being charged Charge off battery is fully charged 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.
