Toshiba SL-4700 用户手册

Make sure that the work surface is firm, steady and free 
from vibration and draughts.

Hold the scale by the base when picking up.  Do not 
pick up the scale by the weigh plate or cross.

Adjust the feet if the scale is not level.

To avoid the risk of RSI (Repetitive Strain Injury) it is 
important to ensure that the machine is placed on a 
surface which is ergonomically satisfactory to the user. 
In cases where usage is prolonged EN614-1 
recommends frequent breaks for the user.
