Safety and compliance warnings 11Safety and compliance warningsRadio frequency exposure informationFor your own safety and to ensure you comply with the Federal Communication Commission’s (FCC) radio frequency (RF) exposure guidelines, please read the following information before using this radio.Using this radioYou should use this radio only for work-related purposes (it is not authorized for any other use) and if you are fully aware of, and can exercise control over, your exposure to RF energy. To prevent exceeding FCC RF exposure limits, you must control the amount and duration of RF that you and other people are exposed to.It is also important that you:■Do not remove the RF Exposure label from the radio.■Ensure this RF exposure information accompanies the radio when it is transferred to other users.■Do not use the radio if you do not adhere to the guide-lines on controlling your exposure to RF.Controlling your exposure to RF energyThis radio emits radio frequency (RF) energy or radio waves primarily when calls are received and made. RF is a form of electromagnetic energy (as is sunlight), and there are recom-mended levels of maximum RF exposure. To control your exposure to RF and comply with the maxi-mum exposure limits for occupational/controlled environ-ments, follow these guidelines:■Do not talk (transmit) on the radio more than the rated transmit duty cycle. This is important because the radio radiates more energy when it is transmitting than when it is receiving.
12 Safety and compliance warnings■While you are transmitting (talking or sending data) on the radio, you must ensure that there is always a distance of 0.9m (35 inches) between people and the antenna. This is the minimum safe distance.■Use the radio only with Tait-approved antennas and attachments, and make only authorized modifications to the antenna otherwise you could damage the radio and violate FCC regulations.For more information on what RF energy is and how to control your exposure to it, visit the FCC website at http://www.fcc.gov/oet/rfsafety/rf-faqs.html.Compliance with RF energy exposure standardsThis two-way radio complies with these RF energy exposure standards and guidelines:■United States Federal Communications Commission, Code of Federal Regulations; 47 CFR part 2 subpart J ■American National Standards Institute (ANSI) / Institute of Electrical and Electronic Engineers (IEEE) C95. 1-1992■Institute of Electrical and Electronic Engineers (IEEE) C95.1-1999 Edition.This radio complies with the IEEE (FCC) and ICNIRP exposure limits for occupational/controlled RF exposure environments at operating duty factors of up to 50% talk to 50% listen.
Safety and compliance warnings 13Warning: Safe radio operation■Switch the radio off at petrol filling stations or near flammable liquids or gases.■Switch the radio off in the vicinity of explo-sive devices and blasting zones.■Using a handheld microphone or a radio while driving a vehicle may violate the laws and legis-lation that apply in your country or state. Please check the vehicle regulations in your area.Caution: EN 60950 requirementsThis radio complies with the European Union standard EN 60950 when operated up to the rated 33% duty cycle of two minutes transmit and four minutes receive, and with ambient temperatures of 30°C or lower.Operation outside these limits may cause the external temper-ature of the radio to rise higher than this standard permits.Caution: High temperaturesThe bottom surface of the radio and the heatsink fins can become hot during prolonged operation. Do not touch these parts of the radio.Important: Radio protectionAlways remove the fuses from the radio power cable before charging the vehicle battery, connecting a second battery or using power from another vehicle (e.g. when “jump-starting” the vehicle).
14 Getting startedGetting startedThis section provides a brief description of your radio’s basic operation. If you need further information, contact your radio provider.Radio controlsThe radio controls are the PTT key, volume control, on/off key, scroll keys, selection keys and function keys. Some keys may have functions assigned to both short and long key presses: ■a short key press is defined as less than one second, and ■a long key press is more than one second.The radio controls and their functions are summarized in the diagram and table on the following page.

To go to your quick access menu, press a scroll key or , and the menu is displayed.For example, if your channels menu is your quick access menu, press a scroll key or to go directly to the channels menu.Selecting a channel or groupTo select a channel or group you can either:■use the scroll keys or to scroll through the channel list until the channel or group you want is displayed, or■use the menu (see “Using the radio menu” on page 19).Making a callThe network that your radio is operating on determines the way you make a call. The two network options that affect the calling procedure are:■conventional, and■MPT trunked.Making a call on a conventional network1. Select the required channel, group or zone.2. Check the green LED.If the green LED is glowing, the channel is busy and you cannot transmit.3. Once the channel is clear (the green LED is off), lift the microphone off the microphone clip.4. Hold the microphone about 5cm (2 inches) from your mouth and press the PTT key to transmit.
Basic operation 215. Speak clearly into the microphone and release the PTT key when you have finished talking.Note: You cannot change channels while transmitting.Making a call on an MPT trunked network1. Select the required channel, and press the PTT key.2. Once the person you have called replies, lift the micro-phone off the microphone clip.3. Hold the microphone about 5cm (2 inches) from your mouth and press the PTT key to transmit.4. Speak clearly into the microphone and release the PTT key when you have finished talking.Transmit timerYour radio may have a transmit timer that limits the amount of time you can transmit continuously. When the transmit timer is about to expire, the red LED flashes and the radio gives three beeps. You must release the PTT before you can transmit again.Note: Your radio may be unable to transmit for a short time after the transmit timer has expired.Receiving a callWhen there is valid activity on your radio’s currently selected channel or group, the radio then unmutes and you can hear the call.If the incoming call contains special signalling that matches the signalling programmed for your radio, the green LED flashes and your radio may give a ringing tone.
22 Basic operationChanging networks1. Press Menu and scroll through the list of menu items until Networks is displayed.2. Press Select to enter the Network Menu and the current network is highlighted.3. Scroll down the list until the required network option is displayed, and press Select.4. Press Yes when you are prompted to confirm your selection.What you hear on a channelYour radio may be programmed so that you hear all conversa-tions on a channel, or your user group may be segregated from other user groups by using special signalling. The special signalling is used to control the muting and unmuting of your radio, so that your radio is muted when other user groups are talking and unmuted for members of your user group.The two muting controls that operate in your radio are:■signalling mute, and■squelch.
Basic operation 23Signalling muteThe radio’s signalling mute only allows the radio to unmute if the incoming call carries the tones specific to your user group. Your user group may use tones that are either audible, subaudible or both.SquelchThe radio’s squelch allows the radio to unmute only when the strength of the incoming signal is above a predetermined threshold. This means that only signals of reasonable intelli-gibility are made audible.Checking that a channel is clearUse the monitor function to check that the channel is clear before you make a call. While monitor is on, the green LED flashes continually and the monitor icon is displayed.To activate monitor, you can either:■use a function key that may have been programmed for monitor, or■use the menu.Activating monitor using the monitor function key1. Press the monitor function key and monitor overrides the signalling mute, allowing you to hear any traffic on the channel.Note: Your radio may be programmed to activate monitor whenever the microphone is off the microphone clip.2. Press the monitor function key again to turn monitor off.
24 Basic operationActivating monitor using the menu1. Press Menu, and scroll through the list of menu items until Function Settings is displayed.2. Press Select to enter the func-tion settings menu, then scroll down the list of menu items until Monitor is displayed.3. Press Select to select monitor, then Select to select On.
Troubleshooting 25TroubleshootingWhen your radio won’t turn onIf the red, green and amber LEDs on the control head do not light up when the radio is turned on, it is likely that no power is reaching the radio. Check the following:■Is the power connector firmly plugged into the rear of the radio?■Are the in-line fuses in good condition?■Is the power cable securely connected to the vehicle bat-tery or power supply?If all appears to be in order, then contact your radio provider for further assistance.Removing the radio from the vehicle1. Switch off the radio.2. Unscrew the four thumb screws that secure the radio to the U-bracket .3. Lift the radio clear of the U-bracket.4. Disconnect the antenna and power cable from the rear of the radio.baacdabcd

30 Installation warningsInstallation warningsWarning: Safe radio mounting■Mount the radio securely so that it will not break loose in the event of a collision. An unsecured radio is dangerous to the vehicle occupants.■Mount the radio where it will not interfere with the deployment of passenger air bags.■Do not mount the radio vertically, with the control head facing down. This will violate compliance with the Euro-pean Union standard EN 60950, Safety of Information Technology Equipment.Warning: Interference with vehicular electronicsSome vehicular electronic devices may be prone to malfunc-tion, due to the lack of protection from RF energy present when your radio is transmitting.Examples of vehicular electronic devices that may be affected by RF energy are:■electronic fuel injection systems■electronic anti-skid braking systems■electronic cruise control systems.If the vehicle contains such equipment, consult the vehicle manufacturer or dealer in order to determine whether these electronic circuits will perform normally when the radio is transmitting.Warning: Liquefied petroleum gas powered vehiclesRadio installation in vehicles powered by LP (liquefied petro-leum) gas with the LP gas container in a sealed-off space within the interior of the vehicle must conform to the National Fire Protection Association Standard NFPA 58. This standard states that the radio equipment installation must meet the following requirements.
Installation warnings 31■The space containing the radio equipment shall be iso-lated by a seal from the space containing the LP gas con-tainer and its fitting.■Outside filling connections shall be used for the LP gas container and its fittings.■The LP gas container space shall be vented to the outside of the vehicle.Important: Non-standard radio installationsThe installation U-bracket described in this guide has been designed so that there is enough airflow around the radio to provide cooling.If a non-standard installation method is used, care must be taken that sufficient heat can be dissipated from the radio heatsink fins and the bottom surface of the radio chassis. For this to be achieved, there must be a gap of more than 10mm (0.4 inch) between the bottom surface of the radio chassis and the mounting surface. This is illustrated in the following diagram.Important: Negative ground supplyTM8200 radios are designed to operate only in a negative ground system.10mmmounting surface
32 Installation planningInstallation planningThe procedures outlined in this and the following sections are for installing a TM8250 or TM8255 radio in a vehicle, using a standard U-bracket.MPT 1362 code of practiceTM8200 radios should be installed in accordance with the MPT 1362 Code of Practice. This code of practice covers the installation of mobile radio equipment in land based vehicles and has been developed by the United Kingdom Radiocom-munications Agency.The full text of the MPT 1362 Code of Practice can be found at the Radiocommunications Agency website,www.radio.gov.uk.Checking equipmentUnpack the radio and check that you have the following items:■radio control head with connecting loom■radio body■microphone with microphone clip and screws (TM8255 only)■installation kit, consisting of:— U-bracket with screws— power cable with DC connector— 10A fuses— fuse holders— BNC antenna plug.Installation toolsThe following installation tools may be required:■portable drill■8mm (0.3 inch) socket■BNC crimp tool

36 Radio InstallationInstalling the microphoneImportant: The microphone grommet must be installed whenever the microphone is plugged into the micro-phone socket. When installed, the grommet has two functions:■to prevent damage to the microphone socket when there is movement of the microphone cord, and■to ensure that the control head is sealed against water, dust and other environmental hazards.1. Plug the microphone into the microphone socket on the control head.2. Slide the microphone grommet along the microphone cord and push two adjacent corners of the grommet into the microphone socket cavity.3. Squeeze the grommet and push the remaining corners into position.4. Check that the grommet is seated correctly in the cavity.Installing the antennaInstall the external antenna according to the supplier’s instructions. Good quality 50 ohm coaxial cable must be used, such as RG58 or UR76.Important: The cable should be routed in a manner that minimizes coupling into the electronic control systems of the vehicle.Warning: RF exposure hazardTo comply with FCC RF exposure limits, this product must be installed using an externally mounted antenna with either a 2.15dBi or 5.15dBi gain.microphonegrommetcontrol head
Radio Installation 37This antenna must not be mounted at a location such that any person or persons can come closer than 0.9m (35 inches) to the antenna.Antenna termination1. Run the free end of the coaxial cable to the radio’s mounting position and cut it to length, allowing 20 - 30cm (8 - 12 inches) excess.2. Terminate the free end of the cable with the BNC plug supplied.Power cableImportant: This radio is designed to operate from a nominal 12V negative ground supply and may draw up to 8A of current. The radio will tolerate a supply voltage range of 10.8V to 16.0V at the radio.In vehicles with a supply voltage greater than 16.0V, such as many trucks, it is essential to provide a suitably rated DC to DC converter. This will isolate the radio from excessive battery volt-age and provide the correct DC operating conditions.Installing the power cableImportant: Disconnecting the vehicle’s battery may cause problems with some electronic equipment, such as vehicle alarms, engine management systems and in-car entertainment systems. Check that the vehicle owner has the necessary information to make all electronic equipment func-tion correctly after battery reconnection.1. Disconnect the vehicle’s battery, unless specifically prohibited from doing so by the customer, vehicle manu-facturer, agent or supplier.If the battery is not disconnected, exercise extreme caution throughout the installation and install the fuses only when the installation is ready to be checked (see “Installation checks” on page 40).
38 Radio Installation2. Determine where the power cable will be routed. Important: The power cable should be protected from engine heat, sharp edges and from being pinched or crushed.3. Cut the negative and the positive wires where the in-line fuse holders will be placed (as close to the battery as possible).Note: Do not install the fuses until the installation is ready to be checked.4. Insert each end of the negative wire into one of the in-line fuse holders and crimp them to force the metal contacts onto the wires. 5. Connect the negative wire to the battery ground.6. Repeat step 4 for the positive wire and connect it to the positive terminal of the battery.Installing the radio in the U-bracket1. Connect the antenna and power cables to the rear of the radio.2. Position the radio in the U-bracket so that the holes in the U-bracket line up with the holes in the radio chassis.3. Screw the radio into position using the four thumb screws but without fully tightening the screws.
Radio Installation 394. Position the radio in the U-bracket for best viewing angle, then tighten the thumb screws.Microphone clip (TM8255 radios only)Install the microphone clip in the most convenient location for the radio user. It must be within easy reach of the user, but in such a position that the microphone PTT key cannot be inadvertently activated or jammed on.TM8250 connectorsThe TM8250 control head has two RJ45 sockets for program-ming, and a power on/off LED.Note: The pins of the two programming connectors are connected in parallel, so care needs to be taken when connecting external devices to these connectors.The pin allocations for these connectors are explained in the following diagram and table.programming connector 1programming connector 2LEDPinProgramming connectorsDescriptionON/OFF hardware power on/software power off13.8V unswitched 13.8V power supplyRX AUD receive audio outputMIC AUD microphone audio inputRS485- RS485 compliant output
40 Other installation optionsInstallation checks1. Insert the fuses into the power leads.2. TM8255 radios only.Switch on the radio to confirm that it is operational (see “Turning the radio on and off” on page 19).Important: Do not transmit yet.3. Connect an in-line power meter between the radio and the antenna and measure the forward and reflected power levels.Less than 4% of the forward power should be reflected. If this is not achieved, check the installation, including the antenna length.4. TM8255 radios only.Once the reflected power levels are within tolerance, make a call to another party on the radio (see “Selecting a channel or group” and “Making a call”, on page 20).Other installation optionsContact your radio provider for further information.RS485+ RS485 compliant outputAGND analogue groundDGND digital groundPinProgramming connectorsDescription
