Ikegami HTM-1517R Operation Manual page 29

① MATRIX IN switch
This switch is used to change the matrix ratio
between luminance and color-difference signals.
At the ON (LED on) position, the matrix level is
close to that of a common home-use receiver.
Be sure to keep this switch off when taking the
procedure (4) Adjusting the color balance in 4-
6. Adjustment Procedure.
② SET UP switch
When set to ON (SET UP side/ LED is ON), the
vertical deflection is reduced, facilitating adjust-
ments of the white balance (R/G/B BACK
GROUND).
③ FORCED COL/MONO switch
(Functions only when the NTSC decoder is mounted)
The function of this switch differs as follows accord-
ing to the state of the MONO switch on the front
panel. This switch functions only when analog/digi-
tal (4Fsc:D2/3) composite signals are input.
FORCED MONO
COL/MONO SWITCH
SWITCH
AUTO COLOR
Switches the COLOR/MONO circuit operation
OFF OFF
of the decoder automatically according to
whether burst is added to the composite signal.
FORCED COLOR
The COLOR circuit is operated forcibly re-
ON OFF
gardless of whether burst is added to the
composite signal.
NORMAL MONO
Normal MONO state. In the case of the com-
posite signal, either the COMB or TRAP fil-
OFF ON
ter circuit operates according to the state of
the COMB switch for composite signals.
WIDE BAND MONO
Neither the COMB nor TRAP filter circuit
operates in the MONO state. Frequency
ON ON
characteristics of the luminance signal are
in the full-flat state.
Beam Feedback Line
SET UP line for reduced
vertical deflection
Function
④ EXT SYNC switch
Set this switch to EXT when externally synchro-
nizing the analog input signal. The switch does
not function when digital signals are input.
⑤ RE.SC switch
(Functions only when the DE-801 module is
mounted)
Use the RESIDUAL SUBICULAR ON/OFF switch
to check if the subicular is leaking to the signal
input.
Press this switch while observing the screen. If
the phase (HUE) changes, it means that the sub-
icular is leaking into the feedback line area.
Releasing the switch automatically sets it to OFF.
⑥ CHANGE PRESET switch
Press this switch to change or memorize the PRE-
SET data.
When pressed, all the PRESET LEDs in the frame
start to blink. Select a blinking PRESET switch.
When the LED stops blinking and stays lit on, the
data can be changed using the rotary encoder.
Press another PRESET switch to change another
data.
Each PRESET data has the following individual
data.

* When changing the PRESET data, do not switch
the Aspect, SCAN and the channels.
