Scale System Care and Maintenance
Cleaning
1. Mild soap/water recommended for general
cleaning/disinfecting.
2. Exercise caution when cleaning LCD window.
Electrostatic Discharge (ESD)
Integrated circuits and semiconductors on printed
circuit boards may be damaged by electrostatic
discharge (ESD). Be sure to use proper handling
precautions at all times.
Electromagnetic Immunity
Electromagnetic Immunity is always relative and
standards are based on anticipated environments of
usage. If the user notes unusual device behavior, this
could be an indication of electromagnetic interference.
If such behavior is observed it may be associated
with the nearby usage of radio or tv transmitters, cell
phones, electro-surgical equipment, etc. and the user
should try moving the interfering equipment further
from this device.
