5. Adjusting Procedure (VE710s-2/VE710b-2/VA721) 5.1. ADJUSTMENT CONDITIONS AND PRECAUTIONS 1. Approximately 30 minutes should be allowed for warm up before proceeding. 2. Adjustments should be undertaken only on those necessary elements since most of them have been carefully preset at the factory. 3. ESD protection is needed before adjustment. MAIN ADJUSTMENTS NO. FUNCTION 1. White Balance 2. GEOMETRY DESIGNATION Function Key Function Key 5.2. 5.3. ALIGNMENT PROCEDURES Adjustment Conditions and Precautions: (A). Power supply voltage: AC 110/120V±10% 60 Hz±5%, AC 220/240V±10% 50 Hz ±5%. (B). Warm up time: The display must be power ON for at least 30 minutes at full white pattern before starting alignments. This is especially critical in color temperature and white balance adjustments. (C). Signals: reference the front detail specifications and timing table. Video : reference the front detail specifications. 1. Adjustment of White Balance: A. TIMING: 1280x1024 64KHz/60Hz. B. PATTERN: 5 Blocks. C.
