**SPECIAL WARNING**

Cell-Phones, Cordless-Phones, and any radio-frequency device can cause

temporary interference and cause the scale to temporarily not work properly.

Please do not use any electronic device near the SCALE. Just like in an

Airplane, do not use your cell-phone near the scale when it is in use. While

there is NO risk of permanent damage to the scale, interference can cause an

incorrect calibration or incorrect weight readings.
