   CAUTION 

 

A CAUTION statement indicates a potentially hazardous situation that may result 
in personnel injury or equipment damage. 

 

   CAUTION 

 

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

  

DIRECT FUNCTION” 

and Section

 37. “Configuration 

Diagram of Peripheral Units.”

 

 

Ÿ 

DO NOT disassemble the balance, accessories, or peripheral unit.
