CAUTION
•
Check the specifications of the DC power supply input terminal and use a power supply that is compatible with the video display.
Using a power supply with incompatible voltage and polarity may cause fire or electric shock.
•
Use a DC power cord with an allowable current of at least 10 A and a length of 2 m or less. If a DC power cord longer than
2 meters is used, the video display may not work normally, for example, the video becomes choppy or nothing is displayed.
•
Do not connect cables for audio devices or sound cables to the DC power supply input terminal, as it may cause damage to the
display unit.
Note
•
Warming-up is necessary to stabilize the brightness of the video display. Wait at least 10 minutes after turning on the power before
use.
•
When an AC power supply is connected during the use of DC power supply, the power source is switched to AC power supply.
When this happens, the power is turned off temporarily and then turned on again.
