Figure 1-1 sWarning : Do not force the LCD Monitor over its maximum viewing angle settings as stated above. Attempting this will result in damaging the Monitor and Monitor stand. Detaching LCD Monitor from Its Stand 1. Remove the rear panel (1) from the monitor. Remove the rear support panel (2) from the swivel base support column. Unscrew screws (3) the swivel base support column (4). Figure 1-2 3 Interface for Arm Applications Before connecting the display to the swivel base support column, please refer to Fig. 1-2. The rear of this LCD display has four integrated 4 mm, 0. 7 pitches threaded nuts, as well as four 5 mm access holes in the plastic covering as illustrated in Figure 1-3. These specifications meet the VESA Flat Panel Monitor Physical Mounting Interface Standard (paragraphs 2. 1 and 2. 1. 3, version 1, dated 13 November 1997) Figure 1-3 Cable Installation Please follow these instructions to install the cables. Remove the back panel (1) from the rear of the monitor. Remove the rear support panel (2) from the swivel base support column 3. Place the signal cable, the DC power cable and the audio cable into their correct respective grooves (3). Figure 1-4 Connecting the Display to your Computer 1. Connect one end of the signal cable to the LCD Monitor's VGA port. Connect the other end of the signal cable to the VGA port on your PC. Make sure connections are secure. Figure 1-5 Attention : This device must be connected to an off-the-shelf video cable in order to comply with FCC regulations. A ferrite-core interface cable is included in the LCD Monitor package. This device will not be in compliance with FCC regulations when a non-ferrite-core video cable is used. Connecting the AC Power 1. Connect the power cord to the AC adapter. Connect the AC adapter's DC output connector to the DC Power Jack of the monitor. Connect the power cord to an AC power source. Warning: We recommand to install a "Surge Protector" device between the AC Adapter and the electrical wall outlet for adding protection against power surges to prevent the effects of sudden voltage variations from reaching the LCD Monitor. Sudden power surges may damage your monitor. Figure 1-6 Connecting the Audio Cable 1. Connect the audio cable to the " LINE OUT " jack on your PC's audio card or to the front panel's "AUDIO OUT" jack of your CD ROM drive.
