IMPORTANT NOTICES
HEALTH AND SAFETY
1 All personnel are required to study these notices and familiarise themselves with all
applicable safety precautions and bring them to the attention of others in the vicinity.
HIGH VOLT AGE WARNING
LETHAL HIGH VOLTAGES ARE PRESENT IN THE TRANSCEIVER
2 A current of 100 mA passing through the human body for one second can kill. This can
occur at voltages as low as 35 V AC or 50 V DC. Some equipment in the system uses
electrical 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 be
undertaken by qualified personnel who are fully aware of the danger involved and who
have taken adequate safety precautions to avoid contact with dangerous voltages.
HEALTH HAZ ARD
4 This equipment contains materials which produce toxic fumes when ignited.
5 The inhalation of dust and fumes or any contact with lubricants when cleaning the
equipment may be temporarily harmful to health, depending on individual allergic
reactions. Components which are broken or overheated may release toxic fumes or dust and
must be treated with caution. Do not inhale the fumes and ensure that the dust and debris do not
enter open cuts or abrasions. It is prudent to regard all damaged components as being potentially
toxic, requiring careful handling and appropriate disposal.
