Do not romove the cabinet back from your set. Refer servicing to qualified service personnel. Warning To prevent fire or electrical shock hazard, Do not expose the main unit to rain or moisture. Warning Do not drop or push objects into the television cabinet slots or openings. Never spill any kind of liquid on the television receiver. Minimum 10c 10c 5cm ! Caution 20c If the television is to be built into a compartment or similarly enclosed, the minimum distances must be maintained. Heat build-up can reduce the service life of your television, and can also be dangerous. ! Caution Never stand on, lean on, push suddenly the product or its stand. You should pay special attention to children to children. ! Caution Do not place the main unit on an unstable cart stand, shelf or table. Serious injury to an individual, and damage to the television, may result if it should fall. ! Caution When the product is not used for an extended period of time, it is advisable to disconnect the AC power cord from the AC outlet. ! Caution Avoid exposing the main unit to direct sunlight and other source of the heat. Do not stand the television receiver directly on other produces which give off heat. E. g. video cassette players,Audio amplifiers. Do not block the ventilation holes in the back cover. Ventilation is essential to prevent failure of electrical component. Do not squash power supply cord under the main unit. ! Caution The LCD panel used in this product is made of glass. Therefore, it can break when the product is dropped or applied with impact. Be careful not to be injured by broken glass pieces in case the LCD panel breaks.

channel 1 SGND is the input signal ground reference SVRR is the midrail bypass mode enable OUT1 is the audio output for channel 1 PGND is the power ground refernce OUT2 is the audio output for channel 2 VCC is the supply voltage input. M/SB is the mute/standby mode enable. When held at less than 2V, this signal enables the TPA1517 for standby operation. When held between 3.4V and 8.8V, this signal enables the TPA1517 for mute operation. When held above 9.2V, the TPA1517 operates normally. IN2 in the audio input for channel 2 GND/HS are the ground and heat-sink connections. ALL GND/HS terminals are the connected directly to the mount pad for thermal-enhanced operation.
