ODo not use the device in any place subjected to direct
sunlight, as this may cause the internal temperature
to rise, resulting in unstable operation. In some
cases, this may also result in damage to transistors or
ICs in the device.
OA void using the device in locations subjected to high
temperatures or humidity.
ODo not use the device in locations that are particularly
subject to vibrations, as this may cause misoperation.
OUse the device with an AC power supply that supplies
a voltage lying within + / - 10% of the device's rated
voltage. The supply frequency should be 5 0 / 6 0 Hz.
ODo not apply voltages externally to any of the output
terminals (RF OUTPUT, SYNC OUTPUT, VIDEO
OUTPUT, S U B CARRIER, etc.).
OWhen connecting the device into a TV receiver, to
avoid electrical shock, be sure to remove the receiv-
er's electrical cord from the AC socket.
OWhen operating the push-buttons, push gently on
the center of the buttons.
OWhen using the device in connection to a TV
receiver, be sure to match the device's RF channel
correctly to that of the TV receiver.

Plug the powercord into an AC socket AFTER you have
made sure that the voltage of your power supply
matches the voltage to which the SUPPLY VOLTAGE
switch on the rear panel is set. Push the POWER switch
(1). The POWER LED will light up and the device will
enter the operating state. At this point, the pattern
selected via the push-button will display.

When using the device for the adjustment, investiga-
tion, or repair of TV receivers, please be careful of the
following points.
1) Disconnect the feeder or coaxial cable from the
ANTENNA terminal of the receiver.
2) Check the characteristics and impedance of the
ANTENNA terminal.
3) Check whether or not any high voltages or AC
voltages are leaking to the ANTENNA terminal. If
there is a leakage voltage, connect the device via a
condenser having a proof voltage corresponding to
this leakage ( 1 0 - 1 0 0 0 pF).
