TRANSMITTER SAFETY PRECAUTIONS:
AC VOLTAGES USED FOR THE OPERATION OF THIS EQUIPMENT ARE DANGEROUS TO HUMAN
LIFE!
This instruction manual has been written for the general guidance and information of operation,
maintenance and service personnel who are aware of, and are familiar with, the hazards of working with
high powered electronic circuits.
This manual does not purport to detail all of the safety precautions that should be observed when servicing
this or any other electronic equipment. Servicing by inadequately trained or inexperienced personnel may
expose such personnel to serious risks that could result in personal injury or death, and/or damage to this
equipment. All personnel concerned with the servicing of this equipment should be thoroughly familiar
with standard first aid procedures for the treatment of electrical burns and shock.
The equipment has been designed to protect operating personnel from accidental contact with voltages
dangerous to human life, either by means of distance (where it is necessary to deliberately reach to make
contact with live terminals) or with shielding. It is therefore of prime importance that any protective
covering devices are kept in place at all times.
While all practical safety precautions have been adopted to safeguard personnel from possible injury, in
times of off-air emergency there is often a strong tendency to act without due regard for normal caution;
for this reason, both supervisory and operating personnel are urged to
ENSURE THAT THE SAFETY
RULES DETAILED BELOW ARE FOLLOWED AS AN ESTABLISHED ROUTINE
at all times.
1.
KILL THE AC POWER BEFORE IT KILLS YOU
Under no circumstance should any person reach within the cabinets for the purpose of servicing or
adjusting the equipment without first disconnecting the AC power, or without the immediate presence of
another person capable of rendering aid. Use of the buddy system is encouraged for transmitter work.
2.
DO NOT TAMPER WITH INTERLOCKS OR SAFETY SHIELDS
Under normal circumstances no safety shield should be removed.
3.
REMOVE PERSONAL JEWELRY WHEN WORKING ON THE EQUIPMENT
The 48 volt power supply in this transmitter, although overload protected, is able to deliver currents
capable of heating metallic tools or personal jewellery such as a watchband, bracelet, or ring. Accidental
short circuits from such metallic objects can cause them to heat sufficiently to result in serious personal
injury.
4.
KNOW FIRST AID, AND KEEP FIRST AID SUPPLIES AVAILABLE
Illustrated first aid instructions for the treatment of electrical shock and burns should be displayed in a
prominent location adjacent to the equipment. In rendering first aid, the timeliness and effectiveness of
the treatment are vitally important to the recovery of the injured person.
Without exception, all personnel should thoroughly familiarize themselves with the procedures involved.
One person, whose regular duties place him or her at the transmitter site often, should be delegated and
given the complete responsibility and authority to ensure that first aid supplies are kept on site and
maintained fresh and up to date.
Prominently display a list of emergency telephone numbers. This list should include the telephone
numbers of the nearest ambulance, hospital, doctor, and fire department paramedics; and the public
works (highways or county roads) department in case the former persons need access to the site during
inclement weather.
