16 Safety and Servicing Information
Warning!!
Do not operate TB8100 equipment near electri-
cal blasting caps or in an explosive atmosphere.
Operating the equipment in these environments
is a definite safety hazard.
Caution
Beryllium Oxide
The termination resistors used in the 100W power
amplifier contain some beryllium oxide. This sub-
stance is perfectly harmless in its normal solid form,
but can become a severe health hazard when it has
been reduced to dust. For this reason the termina-
tion resistors should not be broken open, mutilated,
filed, machined, or physically damaged in any way
that can produce dust particles. You should safely
dispose of all used or obsolete components accord-
ing to your local regulations.
Do not operate the transmitter when someone is standing within 90cm (3ft)
of the antenna. Do not operate the transmitter unless you have checked that
all RF connectors are secure.
Take care when handling a PMU or PA which has been operating recently.
Under extreme operating conditions (+60°C [+140°F] ambient air
temperature) or high duty cycles the external surfaces of the PMU and PA
can reach temperatures of up to +80°C (+176°F).
Caution
The magnetics and power devices attached to the
heatsink in the PMU get hot when they are operat-
ing. Take care when working on a PMU that has
been in recent use.
Caution
Touching high-power RF components or circuits
can cause serious burns. We strongly recommend
you do not touch any RF components or tracks in
the PA while it is transmitting.
