Ps
In case of TTL level sync signal, set this switch to HIGH side,
Fur keeping fine quality of the picture, please avoid connecting 3 monitors
or more as loop through strings.
The input impedance selector switches of the units in a Yoop-through-strings
should be set to HIGH side.
The input impedance selector switches of Lhe last unit in a loop-through-stringds
should be set to “750” side to terminate signal cables.

_ Check whether the power cord is plugged into the electrical outlet, and/or
the AC inlet of the monitor.
- Confirm that the electrical outlet is active and works properly.
(3) Check connection

+ Confirm that the electrical outlet works properly.
(2) Check that the horizantal picture width is adjusted properly,
+ When the horizontal picture width is set too wide, the protection circuit
in the monitor is activated.
Beep sound is generated and both sides of the picture fluctuate when the
protection circuit is active,
Please adjust the horizontal width control to get narrower picture.

If you cannet get the stable picture on the screen, please check the following
items: -
(1) Check connection. (Refer to 5.1(3))
(2) Check the level of the sync signals.
The level of the sync signals are shown in specification (Refer to Section 6!
when using composite/ external sync.
(3) Confirm the horizontal scanning frequency,and the vertical scanning frequency.
- The monitor can accept only.folowing signal.
Horizontal scanning frequeny “the = 15.7kHz - 38kHz
Vertical scanning frequency 40Hz - 90Hz
(4) It needs approx. 5 seconds to get the stable picture after the sync signals
