Part 1: General Information 4. COMMENTARY 4.1 External appearance design This product follows the same design concept and coloring as the earlier models, LV7325/LV-7320 to establish a unified image for Canon Multimedia Projectors. Some of the major design points, which are basically the same as the other Canon Multimedia Projectors, are outlined below. ● External Styling The body is designed with subtle curves and the coloring and semi-transparent body panels follow the lead of the LV-7300 series.
Part 1: General Information 4.3 Fan speed control A new feature of this projector is Real Time Fan Control. Temperature sensors control the fan to reduce the fan noise level to an unobtrusive level (39dB) during normal operation. There are two temperature sensors, sensor 1 measuring ambient room temperature and sensor 2 measuring the temperature in the area of the LCD panels. The outputs of the sensors are sent to the CPU, which then controls the voltage applied to the fan as outlined below. 1.

■ Printed Wiring Board Diagrams (LV-5110U/E) CAUTION This projector is isolated from AC line by using the internal converter transformer. Please pay attention to the following notes in servicing 1. Do not touch the part on hot side (primary circuit) or both parts on hot and cold sides (secondary circuit) at the same time. 2. Do not shorten the circuit between hot and cold sides. 3. The grounding lead must be connected to the ground of the same circuit when measuring of voltages and waveforms.
