Acer H233H 23-Inch Widescreen LCD Monitor
Unpacking
Please check that the following items are present when you unpack the box, and save the packing materials in case you need to ship or transport the monitor in the future.
Attaching the base (for selected models)
Note: Remove the monitor and monitor base from its packaging. Carefully place the monitor face-down on a stable surface — use a cloth to avoid scratching the screen.
- Attach the monitor stand arm to the base.
- Ensure that the base is locked onto the monitor stand arm.
Note: Take care when performing the installation to avoid injuring yourself.
Screen position adjustment
To optimize the viewing position, you can adjust the monitor tilt, using both
of your hands to hold the edges of the monitor. The monitor can be adjusted to
15 degrees up or 5 degrees down.
Connecting the power cord
- Check first to make sure that the power cord you use is the correct type required for your area.
- The monitor has a universal power supply that allows operation in either 100/120 V AC or 220/240 V AC voltage area. No user- adjustment is required.
- Plug one end of the power cord to the AC inlet, and plug the other end into an AC outlet.
- For units using 120 V AC: Use a UL-listed cord set, type SVT wire and plug rated 10 A/125 V.
- For units using 220/240 V AC: Use a cord set consisting of H05VV-F cord and plug rated 10 A/250 V. The cord set should have the appropriate safety approvals for the country in which the equipment will be installed.
Power saving
The monitor will be switched to “power saving” mode by the control signal from
the display controller, as indicated by the amber-colored power LED.
The power saving mode will be kept until a control signal has been
detected or the keyboard or mouse is activated. The recovery time from “power
saving” mode back to “on” is around 3 seconds.
Display Data Channel (DDC)
To make installation easier, so long as your system supports the DDC protocol, the monitor is able to plug and play. The DDC is a communication protocol through which the monitor automatically informs the host system about its capabilities; for example, supported resolutions and corresponding timing. The monitor supports the DDC2B standard.
