General Instructions

EZFAST Body Fat Analyzer GBF-2108-B applies BIA (Bio-impedance Analysis) technology. A small amount of weak current flows through the human body so as to detect the bio­ impedance and estimate body fat. The electrical current is small and may not be felt. This BIA technology is cheap, safe, non-invasive, toxic-free and harmless. It also possesses the characteristics of simple operation and abundant information. The current mentioned above is less than 0.5mA. However,  please be aware that anyone with a wearable or implantable medical electronic instrument, such as a pacemaker, must avoid using this device. The intended use of this device is for healthy children 10-17 years old and healthy adults.

Insert the Batteries

• Open the battery door in the back of the scale.
• Insert the batteries (3 x 1.5V AAA) into the battery compartment according to the polarity indications marked inside the compartment
• All digits will be shown on the LED.
  • Close the battery door and wait until the digits “0.0lb” are shown on the LED.

CAUTION

• When the symbol “Lo” appears, the device can only weigh 10 times and then power off. Then you shall replace with a new set of batteries. Please replace all three batteries at the same time. Do NOT mix the old batteries with the new one.
