If the distance between the IR receiver jig and the camcorder is
below 1m, cover the LASER LINK emitter with a ND filter. (For
example, when the distance is 30cm to 50cm, cover the LASER
LINK emitter with a ND filter 1.0.)

• Perform the adjustment using color bar signal as a video signal

input for the VIDEO terminal.

• The items to be adjusted for the R channel will be indicated within

the [ ], in regard to the adjusting items to be adjusted for both L
and R channels.

• Set the Hi-Fi sound switch in the menu display to “STEREO”

position unless specified otherwise.

1) When inputting the audio signal, input same signal to both the L and R

channels, unless otherwise.

2) Be sure insert the plug (Shorting plug or dummy plug, etc) into the

AUDIO terminal (Right). If the plug is not inserted, the monaural mode
will be set, and correct adjustments can not be carried out.

During recording ............... REC AFM RF 1.7MHz carrier will not be

output.

During playback ................ The L + R signal will be output from the

AUDIO terminal (Left).

Connect the audio system measuring instruments in addition to the
video system measuring instruments as shown in Fig. 5-3-19, and
perform adjustments at the power switch [VTR] position.
