1.5.2.5 At the place of entering the building,
before going further to the radio station, the feedline between the amplifier and tuner
input should be equipped with a pulse overvoltage limiter (surge arrester), the ground -
ing terminal of which should be connected through a
low-impedance
connection to
the main grounding plate of the building (Appx.1-8).
1.5.3 Electric Safety Precautions
WARNING HIGH VOLTAGE
The electronics inside the tuner operate under high di-
rect-current voltage up to 200V, which is fatal! Never allow
anyone, especially children, to insert any object into box
holes – this may cause electric shock. Disconnect all ca -
bles from the tuner and every time wait at least 1 minute
before opening it!
WARNING HIGH VOLTAGE
RF voltage at antenna feedpoint and elements may exceed
several thousand volts! Never touch the antenna or an-
tenna isolators during transmission and tuning – this may
cause deep RF burns as well as indirect traumas, such as
falling!
1.5.4 General Safety Precautions
WARNING HIGH VOLTAGE
Do not undertake any repair or alteration in the design or
software of the tuner by yourself, as this may threaten your
