2. SAFETY
In addition to this section, included by reference are the following pertinent sections of the
International Standard IEC-215, ‘Safety requirements for radio transmitting equipment’:
Appendix D, ‘GUIDANCE ON ASSESSING THE COMPETENCE OF PERSONNEL FOR
DESIGNATION AS SKILLED’ and also Sub-clause 3.1 of the Standard.
Appendix E, ‘GUIDANCE ON SAFETY PRECAUTIONS TO BE OBSERVED BY
PERSONNEL WORKING ON RADIO TRANSMITTING EQUIPMENT’, also Sub-clauses 3.2,
3.7 and 22.1 of the Standard.
To prevent the risk of personal injury or loss related to equipment malfunction Advantech uses
the following symbols for safety related information. For your own safety, please read the
information carefully BEFORE operating the equipment.
Symbols used in manual:
WARNING: This indicates a hazardous procedure that could result in serious injury or death if
not performed properly.
CAUTION: This indicates a hazardous and dangerous procedure that could result in light-
to-severe injury or loss related to equipment malfunction, if proper precautions
are not taken.

----------------------------------------------- WARNING -----------------------------------------------------
When supplying power to this equipment, use the 3-pin connector provided, to connect to a
grounded power outlet. If power is supplied without grounding to the equipment, there is a risk
of receiving a severe or fatal electric shock.
In the context of this document any voltage that is lethal is viewed as ‘High Voltage’. Therefore,
even prime power (90 to 265V AC) is dangerous because prime power potentials have been
known to cause death or injury.
----------------------------------------------- WARNING ----------------------------------------------------
This equipment can not be repaired by the operator. DO NOT attempt to remove the
equipment cover or to disassemble internal components. Only qualified service technicians
should service this equipment. There are high-voltage parts in this equipment presenting a risk of
severe injury to untrained personnel. In addition, there is a risk of damage to precision
components.
----------------------------------------------- WARNING ----------------------------------------------------
ALWAYS TERMINATE THE OUTPUT WAVEGUIDE OF THE AMPLIFIER WITH AN
RF LOAD CAPABLE OF DISSIPATING FULL CW RF POWER. SIMILARLY
TERMINATE THE INPUT TO AVOID THE POSSIBILITY OF THE AMPLIFIER
BEING DRIVEN BY STRAY LEAKAGE SIGNALS. Incorporate the termination prior to
applying prime power to the amplifier. This procedure prevents self-oscillation and irradiation of
the local environment. Even if a source is not connected to the amplifier you are working with,
there are situations where the amplifier can go into a self-induced mode and generate high levels
of RF energy. Destruction caused under excessive load voltage standing wave ratio (VSWR) will
void the warranty. Although the equipment has internal protection for VSWR higher than 3:1
and will automatically go in shutdown (with a delay of 1 second), still it is a safe procedure to
avoid unwanted effects.

----------------------------------------------- WARNING ----------------------------------------------------
DO NOT LOOK INTO THE OUTPUT PORT OF THE POWERED RF AMPLIFIER.
Treat the powered amplifier with extreme care. Keep in mind that levels of microwave radiation
that do not induce immediate physical discomfort in most individuals can be sufficiently high to
induce longer term effects. Your eyes are particularly vulnerable parts of your body.
The permissible levels of exposure are quite low compared to the power levels of the amplifiers
built by Advantech (e.g. less than 10 mW versus 20 to 500 W delivered by various units). The
permissible levels are currently being studied by a number of organizations. In the past the U.S.
safety Code established a dosage rate of 10 mW/cm2. Currently there is consideration being
given to reducing the permissible level to 1 mW/cm2in the United States, as has been the case
for several European countries.
