IMPORTANT NOTICESHEALTH AND SAFETY1 All personnel are required to study these notices and familiarise themselves with allapplicable safety precautions and bring them to the attention of others in the vicinity.HIGH VOLTAGE WARNINGLETHAL HIGH VOLTAGES ARE PRESENT IN THE TRANSCEIVER2 A current of 100 mA passing through the human body for one second can kill. This canoccur at voltages as low as 35 Vac or 50 Vdc. Some equipment in the system useselectrical power that can be lethal. Whenever practical, before carrying out installation,maintenance or repair, personnel involved must:(1) Isolate the equipment from the electrical supply.(2) Make tests to verify that the isolation is complete.(3) Ensure that power cannot be accidentally reconnected.DO NOT OPEN ANY OF THE UNITS WHEN THE RADAR IS OPERATIONAL -UNLESS FULLY QUALIFIED TO DO SO.3 If it is essential to work on the equipment with power connected, work must only beundertaken by qualified personnel who are fully aware of the danger involved and whohave taken adequate safety precautions to avoid contact with dangerous voltages.HEALTH HAZARD4 This equipment contains materials which produce toxic fumes when ignited.5 The inhalation of dust and fumes or any contact with lubricants when cleaning theequipment may be temporarily harmful to health, depending on individual allergicreactions. Components which are broken or overheated may release toxic fumes or dust andmust be treated with caution. Do not inhale the fumes and ensure that the dust and debris do notenter open cuts or abrasions. It is prudent to regard all damaged components as being potentiallytoxic, requiring careful handling and appropriate disposal.Page iv Issue 1CD-0844CD-0845
RADIATION HAZARD: NON-IONISINGAERIAL RADIATION HAZARD: INJURY CAN RESULT FROM EXPOSURE TOTHE MAIN BEAM OF A STATIONARY RADAR AERIAL. DO NOT STANDLESS THAN 2m FROM THE CENTRAL FRONT FACE OF THE AERIAL.6 It is accepted in most countries that no significant hazard is presented by radio frequencymean power density levels up to 10mW/cm. RF power levels in excess of this may causeharmful effects, particularly to the eyes.7 Users of cardiac pacemakers should be aware that radio frequency transmissions, candamage some such devices or cause irregularities in their operation. Persons using apacemaker should ascertain whether their device is likely to be affected before exposingthemselves to the risk of malfunction.SAFETY ALOFTAERIAL ROTATION: BEFORE MAINTENANCE TO THE TURNINGMECHANISM TAKES PLACE, DISABLE AERIAL ROTATION.8 When working aloft, ensure that it is brought to the attention of someone in authority atdeck or at ground level and that suitably placed warning notices are posted warning thatwork aloft is in progress. Ensure that the means of access aloft is secure and beware of wet orslippery ladder rungs and working areas.9 When working on or near a radar scanner and other moving or r.f. radiating equipment,ensure that it is switched off and that the fuses have been removed and retained.PERSONAL PROTECTION10 Personal protection must be used whenever the possibility of an uncontrolled hazardexists. For example, a suitable face visor, gloves and a body apron should be worn whenhandling cathode ray tubes, as a precaution against injury in the event of breakage.Issue 1 Page v

Issue 1 Page viiATTENTIONOBSERVE PRECAUTIONSFOR HANDLINGELECTROSTATIC SENSITIVEDEVICESCAUTIONHandling of Electrostatic-Sensitive Semiconductor DevicesCertain semiconductor devices used in the equipment are liable to damage due to staticvoltage. Observe the following precautions when handling these devices in theirunterminated state, or sub-units containing these devices:(1) Persons removing sub-units from an equipment using these devices mustbe earthed by a wrist strap and a resistor at the point provided on the equipment.(2) Soldering irons used during the repair operations must be low voltage typeswith earthed tips and isolated from the mains voltage by a double insulatedtransformer.(3) Outer clothing worn must be unable to generate static charges.(4) Printed Circuit Boards (PCBs) fitted with these devices must be stored andtransported in anti-static bags.CD-1100
