instructions

【1】 Before use

Power supply: AC power supply 100v, 50Hz, 60Hz shared
Light source: DNP standard color viewer oil lamp 10W x 4 pieces
Power consumption: 80W

【2】 Use

(1) Insert the AC100v socket into the power code plug.
※ Attention: Please do not connect power sources other than AC100V.
When using it overseas, I will definitely ask you to use the transformer.
If it becomes a mistake to connect a power source other than AC100V, it will be burned out by installing an internal transformer.
(2) Turn on the power switch.
(3) After being lit with an oil lamp at room temperature (20 ℃), it remains stable for 15-20 minutes.
(4) When the oil lamp is not lit, request confirmation from the street electrical security personnel of other projects.
(5) When the shin king phenomenon of the oil lamp occurred, fix it and turn on the power switch 3-4 times, OFF。

【3】 When the oil lamp is not lit

Please confirm with the electrical security personnel.
(1) Connect current to socket AC100V.
(2) Insert the socket into the viewer's plug.
(3) The power switch of the viewer is turned on.

When the viewer's oil lamp is not on, consider something like the following

(1) When two oil lamps were lit, the fuse on one side of the transformer was melting.
(2) When the four oil lamps are not lit, the fuses of each of the two transformers are melting.
※ Attention: This occurs when powered on other than AC100v as mentioned in (1) and (2) above. The internal burnout of this transformer is the cause.
The exchange of transformers becomes necessary.

【4】 Exchange and cleaning with oil lamps

Place the viewer on a flat table (top) and remove the power code from the socket.
Uninstall in the following order.
(1) Loosen the two coin screws on the upper frame.
(2) If you lift the coin screw on the upper frame 50-60mm with both hands and push it forward, the upper frame will deviate from the solid.
(3) Remove the glass plate and acrylic plate.
Attention: Please be careful with your hands and fingers as the glass panel may be broken.
(Please pay attention to the edge of the board, especially when not wiping with your fingers.)

■ Oil lamp exchange
(1) Also, when one year passes, it lights up for 2000 hours.
(2) Remove the end of the oil lamp tube that is clamped between the fingers of both hands and rotate it 90 degrees.

■ Cleaning work
(1) Please soak alcohol in gauze to wipe off any dirt on the surface of the reflector, acrylic board, and glass.
(2) Cleaning is required every 6 months to 1 year to maintain normal color temperature and brightness. We kindly ask for your assistance.
