the low-voltage installation
.
WA RN IN G ： To avoid electrical shock, the power cord
protective grounding conductor must be connected to ground.
CAUTION：To avoid damaging the instrument, do not use it
In a place where ambient temperature exceeds 40℃.
CAUTION：To avoid damaging the instrument, do not input
more than DC15V to V.C.F.(V.C.G.).
CAUTION：To avoid damaging the instrument, do not input
more than AC150V to Frequency Counter (for GFG-8216A,
GFG-8217A, GFG-8219A, GFG-8250A, and GFG-8255A).
CAUTION：To avoid damaging the instrument, do not input
more than AC10Vpp when proceed EXT modulation
operation (for GFG-8219A, GFG-8255A).
