3 SAFETY INSTRUCTIONS
3.1 Introduction
T.E.M. has always managed to improve the safety standard if its transmitting and receiving equipment. All
produced systems are tested in compliance with international rules.
Obviously this is not sufficient to avoid any accident during the installation and the use of our equipment in
compliance with EN60215 rule, the radio transmitters and the auxiliary equipment must be used by
qualified technical staff only and T.E.M. declines any responsibility for damages caused by an improper use
or improper setting up performed by inexperienced staff, not qualified or operating with instruments or
tools not in compliance with safety set of rules.
WARNING

CURRENT AND VOLTAGE WORKING IN THIS EQUIPMENT ARE DANGEROUS. THE STAFF
MUST ALWAYS OBSERVE THE SAFETY RULES, INSTRUCTIONS AND NORMS CONTAINED
HEREIN.

THE INSTRUCTIONS CONTAINED IN THIS MANUAL MUST BE READ BEFORE SWITCHING ON
OR SETTING THE TRANSMITTER

ANY TRANSMITTER SERVICING, REPAIRING OR CHECKING OPERATION REQUIRING THE
OPENING OF THE TOP OR BOTTOM COVER, MUST BE PERFORMED AFTER THE MAINS
SUPPLY DISCONNECTION WITHOUT REMOVING THE EARTH CONNECTION WHICH THE
EFFICIENCY MUST BE VERIFIED: THE CABLE MUST BE IN GOOD CONDITIONS AND WELL
CONNECTED.

STAFF OPERATING UPON THE TRANSMITTER SYSTEM MUST NOT BE TIRED: AFTER HEAVY
WORKS OR CARRYING HEAVY MACHINES BY HAND, IT IS NECESSARY TO RESPECT A PERIOD
OF REST BEFORE WORKING WITH SYSTEMS WHICH COULD HAVE DANGEROUS ELECTRIC
VOLTAGE IF THEY ARE NOT DISCONNECTED.

SEVERAL SYMBOLS, INSIDE THE TYPICAL TRIANGLE SHOWING DANGER, HAVE BEEN
PRINTED ON SEVERAL TRANSMITTER PARTS. ATTENTION SHOULD BE PAID, BECAUSE THERE
COULD BE THE DANGER DUE TO HOT SURFACES, ELECTRIC VOLTAGE HIGHER THAN 50VOLT
OR OTHER SPECIFIED DANGERS.
Certain devices (for example the RF final circuits mosfets) contain Beryllium Oxide BeO; these components
must not be broken, crashed or heated. This oxide passes through the common systems of filtering,
including the respiratory apparatus. The prolonged inhalation at high degrees causes poisoning with
respiratory apparatus paralysis, till death.
