The following notation conventions are used in this manual to indicate Safety Precautions.
A CAUTION statement indicates a potentially hazardous situation that may result
in personnel injury or equipment damage.
Note:
Provides additional information needed to properly use the balance.
To ensure the proper operation of the balance, observe the following precautions.
• Do not use the balance in hazardous areas.
This includes areas where the balance is exposed to dust and flammable gases or
liquids.
Ÿ Use the AC adapter supplied by CAS.
To prevent the risk of electric shock, never disassemble the AC adapter.
The AC adapter is designed for indoor use. Do not use the adapter in exterior
environments or where it may be splashed by water.
Ensure that the power supply voltage meets the indicated range of the AC adapter.
Ÿ Handle the balance carefully.
The balance is a precision instrument. The door to the weighing chamber is glass,
open and close it carefully.
Ÿ Do not connect the peripheral devices other than those recommended by CAS to the
balance.
The balance may not operate properly if peripheral devices other than those specified
in this manual are used. When using the RS-232C interface, follow the instructions
in Section 34. "Windows
Diagram of Peripheral Units."
Ÿ DO NOT disassemble the balance, accessories, or peripheral unit.
