WARNING!
SAFETY FIRST!
Check for and turn off all power sources before connecting the trans-
mitter directly to otherwise power carrying cables.
Direct connection must NOT be to live 50/60 hertz power sources up to
240 VAC!! The power must be OFF!!
Be certain the transmitter POWER is off before handling the clips on
the conductive assembly. The transmitter can deliver over 100 volts
of signal which is capable of producing electrical shock if not carefully
handled.
