Read instructions—Before the system is installed and operated all the safety instructions should (2). Retain instructions—For future reference the safety instructions and instructions for use should be be read retained. (3). Heed warnings—User should adhere all warnings on the unit and in the installation and operation instructions. (4). Follow instructions—User should follow all installation and operation instructions for use. (5). Cleaning—Before cleaning, system units should be unplugged. Use a damp cloth not liquid cleaners or aerosol cleaners for cleaning. (6). Attachments—The attachments not recommended by the product manufacturer may cause (7). Water and Moisture—In wet location such as kitchen skin, washbowl, bathtub, laundry basket, in a hazards please do not use them. wet basement, in an unprotected outdoor installation, do not use this unit. (8). Accessories—Use this unit only on a stand, tripod, bracket or mount recommended by the manufacturer, or sold with the product otherwise this unit may fall and cause serious injury to a person and serious damage to the unit. (9). Ventilation— If there are openings in the enclosure providing for ventilation, it is to ensure reliable operation of the unit and to protect from overheating. Do not place the unit in a built-in installation unless proper ventilation is provided or the manufacturer's instructions have been adhered to. (10). Power sources—The type of power source indicated on the marking label should be use while operating this unit. If you are not able to make sure of the type of power supply you plan to use, contact our appliance dealer or local power company. If this unit intended to operate from battery power, or other sources, please refer to the "Installation and Operation Instructions". (11). Grounding or polarization—A polarized alternating current line plug (one plug have a blade wider than the other) may be equipped with this unit. This plug will fit into the power outlet only one way. Alternatively, this unit may be equipped with 3-wire grounding type plug having a third (grounding) pin. Only a grounding-type power outlet is suitable to this plug. This is a safety feature. Try reversing the plug when you are unable to insert the plug fully into the outlet. Contact your electrician to replace your obsolete outlet if the plug still fails to fit. Never defeat the safety purpose of the polarised plug. (12). Power-Cord Protection—In order to avoid the power supply cords from walking on or pinching by items place upon or against them, the power supply cords should be routed. (13). Overloading – To avoid fire and electrical shock do not overload outlets and extension cords. (14). Object and Liquid Entry—Do not push any kinds of objects into this unit through openings as they may touch dangerous voltage points or short-out parts which could result in a fire or electric shock. Never spill any kinds of liquid on the unit. (15). Servicing—Never try to service this unit yourself as opening or removing covers may expose to dangerous voltage or other hazards. (16). Damage Requiring Service—Under the following conditions unplug the unit from the outlet and refer servicing to qualified service personnel. 1 l If the unit does not run normally by following the instruction for use. Only adjust those controls that are covered by the instructions for use, because an improper adjustment of other controls may cause damage and will often require extensive work by a qualified technician to restore the units to their normal operation. If the unit has been exposed to rain or water l When the power-supply cord or plug is damaged l If liquid has been spilled, or objects have fallen into the unit (17). Replacement Parts—Make sure that the service technician has used replacements parts specified by the manufacturer or parts which have the same characteristics as the original one when replacing a part. Unauthorized and improper substit-utions may lead to a result of fire, electric shock or other hazards. (18). Safety Check—Ask the service technician to perform safety checks to determine that the unit is in proper operating con-dition after completing any service or repairs to the unit. (19). Lightning—Unplug the unit from the wall outlet and disconnect the cable system for added protection of the units during a Lightning storm, or when it is unattended and unused for long periods of time. The lightning and power-line surges will pr-event damage to the unit. About this manual This manual provides all the information required to install and operate the unit. Safety precautions Warning Do not open the unit when it is connected to mains.The unit contains non-insulated parts,which can cause electric shock Caution There are no user-serviceable parts inside the unit.Service must be done by qualified person. Conventions Warning Follow these instructons to prevent personal injury. Caution Follow these instructions to prevent damage to the equipment. Note Read these instructions for tips and other useful information. 2 2. HANDLING PRECAUTIONS To clean, be sure to switch off the power supply to the unit first, then wipe with a dry cloth. When the unit gets very dirty, use a cloth damped in a neutral cleanser. Never use benzene, thinner or chemically-treated cleaning cloth because such volatile liquids could deform or discolor the unit. Never move the unit from one place to another with the Flash Card inserted because the CompactFlash card may fail. Avoid inserting or withdrawing the CompactFlash card while the unit is in use. 3. INSTALLATION PRECAUTIONS l Do not install the unit in locations exposed to the direct sunlight or heaters, as the unit could be deformed or discolored. l Avoid installing or storing the unit in dusty or humid locations, as doing otherwise could cause the unit's failure. l Keep the unit as far away as possible from a fluorescent lamp, digital equipment, PC or other equipment which generate high frequency noise. l Do not block the ventilation slots on the upper, right and left, and rear sides to allow inside heat radiation. l Keep at least 50 mm space from the unit's right and left sides for heat radiation. Digital Amplifier HPD-4250A HPD-4250A CH 1 CH 2 CH 3 CH 4 ED IT l Never connect the AC power cord to any other line voltage than that specifically designated. l To avoid oscillation, keep the input cable away from the output cable. Particular care must be exercised when mounting the unit in an equipment rack. l In some installations, a ground loop is formed and hum noise may be generated. In such cases, connecting the rear-mounted signal earth terminal to the body of connected equipment (BGM sound source, expansion amplifier, etc.) may reduce it. l Never connect two amplifier outputs in parallel under any circumstances. 3 CAUTION  If there is a need to open the amplifier's top cover when performing work such as mounting optional boards or setting switches, ensure it is done by a qualified service technician.  Make sure to switch the power off before performing any work on the amplifier such as the case above.  Terminals marked with the symbol shows hazardous live and make sure a qualified service personal is involved in making external wiring connections to the terminals or use only those ready-made leads and cords that come along with the unit. 4.
