8. Test Disc JVC :CTS-1000
9. Extension cable for check
EXTSH002-22P 1
Standard measuring conditions
Power supply voltage : DC14.4V(11V~16V allwance)
Load impedance : 4 (4 to 8 allowance)

How to connect the extension cable for adjusting
Dummy load
Exclusive dummy load should be used for AM,and FM. For
FM dummy load,there is a loss of 6dB between SSG output
and antenna input.The loss of 6dB need not be considered
since direct reading of figures are applied in this working
standard.
Standard volume position
Balance and Bass &Treble volume : lndication"0"
Loudness : OFF
BBE : OFF
Frequency Band
FM 87.5MHz ~ 108.0MHz
