Safety Instructions
Please read this section carefully and observe the instructions for you own safety and correct use of the device. It also contains information on approval and interference suppression of your machine. Observe the warnings and instructions on the device and in the manual. In order to maintain this condition and ensure safe operation, the user must observe the instructions and warnings contained in this manual.
The device must be used in accordance with the instruction for use. The electrical installations in the room must correspond to the requirements of the respective regulations. Take care that there are no cables, particularly mains cables, in areas where persons can trip over them. DO NOT use a mains connection in sockets shared by a number of other power consumers. DO NOT use an extension cable. Only use the mains cable supplied. The unit is complete disconnected from the power source, only when the power cord is disconnected from the power source. Therefore the power cord and its connectors must always remain easily accessible. DO NOT set up the device in the proximity of heat sources or in a damp location. Make sure the device has adequate ventilation. All plugs on the connection cables must be screwed or locked to the housing.
NOTE:
DO NOT TOUCH THE BOARD OR ANY OTHER SENSITIVE COMPONENTS WITHOUT ALL NECESSARY ANTI-STATIC PROTECTION.

Electrostatic Discharge (ESD)
A sudden discharge of electrostatic electricity can destroy static-sensitive devices or micro-circuitry. Proper packaging and grounding techniques are necessary precautions to prevent damage. Always take the following precautions:
Transport boards in static-safe containers such as boxes or bags. Keep electrostatic sensitive parts in their containers until they arrive at static-free stations. Always be properly grounded when touching a sensitive board, component, or assembly. Store electrostatic-sensitive boards in protective packaging or on conductive foam.
Grounding Methods Guard against electrostatic damage by following these steps:
1. Cover place with approved anti-static material. Provide a wrist strap connected to a work surface and properly grounded tools and equipment. 2. Use anti-static mats, heel straps, or air ionizes to give added protection. 3. Handle electrostatic-sensitive components, boards, and assemblies by the case or the PCB edge. 4. Avoid contact with pins, leads, or circuitry. 5. Turn off power and input signals before inserting and removing connectors or test equipment. 6. Keep work area free of non-conductive materials such as ordinary plastic assembly aids and Styrofoam. 7. Use field service tools, such as cutters, screwdrivers, and vacuums that are conductive. 8. Always place drives and boards PCB-assembly-side down on the foam.

Assembly, Disassembly
In this chapter, we give the description of how to install/access the components inside the RC-741. CAUTION: Check and make sure that the power supply matches the environment line voltage in your area before turning on the system power. Turn off the system power before connection or disconnecting any peripherals or cables. Electric currents can cause electric shock or damage to the system.
3.1
Removing the Top Cover
Removal of the top cover allows you to access the internal system components of the RC-741. When removing the top cover, follow the instructions listed below.
1. Move your fingertips around the top cover and locate the screws that attach it to the chassis. A total of six (6) screws should be removed to free the top cover. There are 2 screws located at the rear side of the chassis, another 2 on the left side and 2 on the right side of the top chassis rim. Loosen the screws. Secure the screws in a safe place; you will need them when affixing back the top cover. After removing the six (screws), slide the top cover backwards to completely disengage it from the chassis. Lift the top cover and place it aside.
