Initial Start-Up

OPERATION PRINCIPLE
The Body Analyzer uses BIA technology which passes a small amount of weak current through the body to estimate body fat mass, muscle mass, total body water, and other weight components. Contact with the body is made via the stainless steel pads (electrodes) on the scale. The scale simultaneously calculates your body fat percentage, total body water percentage, bone mass, and muscle mass while measuring your body weight, for a more accurate reading of your overall health and fitness.

GETTING STARTED 

Preparing Your Body Analyzer

• Open the battery compartment on the underside of the scale.
• Correctly – in the right polarities, insert the batteries (x4 AAA) into the battery compartment.
• Close the battery compartment.
• Wait until the digits “0.0” are displayed on the LCD screen.
  
• Press the “Unit” button on the underside of the scale to select the desired measurement unit; either pound, kilogram, or stone. The default measurement unit is the kilogram (kg).

CAUTION

• When the symbol “Lo” appears, the device will power off after about 4s. Then you shall replace it with a new set of batteries. Please replace all four batteries at the same time. Do NOT mix the old batteries with the new ones.
• Worn batteries are hazardous waste. Do NOT dispose of them together with the household garbage.

Once all is complete, the display will show “0.0” before powering off. The user settings are now saved.

Repeat the procedure for a second user or to change user details. Note: To update or overwrite the set data, follow the same procedure, making changes as required.

For Weight-Only Measurement

To use the device as a conventional weight scale, no special programming is needed. Once the scale is initialized, simply position yourself appropriately on the scale to measure your current weight.

Note:

1. The scale should be placed on a flat, hard surface. Soft, uneven, or carpeted floors may affect reading accuracy.
2. Ensure you remain still while the scale computes your measurement.
3. After the scale displays your weight value, it will automatically turn off in a few seconds.

For your First Measurement

• Position the scale on a flat, hard surface and single-press the “Set” button to select your User ID.
• Using the “up” or “down” button, cycle through and select the ID that identifies you.
• Once the selected number is locked in, the screen will display “0.0”
• Now, gently step on the scale with your bare feet, ensuring your feet are in good contact with the stainless steel pads (electrodes) on the platform.
• Stand still and remain on the scale until the complete readout is displayed as indicated by full values instead of the moving “0” on the screen.
• Your weight is displayed first, followed by body fat percentage, body water percentage, muscle mass percentage, bone density measurements, and personal parameters settings after 2-3 seconds.
• You can now step off the scale. The measurement will remain displayed on the screen for 10 seconds, after which the device will power off. Start Measuring Note: If the device fails to complete the analysis, only the weight data will be displayed. (Kindly consult the Error and Troubleshooting section for solutions).

Start Measuring

• Ensure the scale is on a hard, flat surface and has been initialized.
• The GBF-830-M uses an original SENSE ON patent technology with automatic user technology, so simply step onto the platform in the correct positioning to take your measurement.
• To obtain a complete, accurate measurement, keep your feet bare when you step on the platform. Body fat and total body water measurements require your feet to be without shoes or socks. Note: The condition of the bottom of your feet might affect the measurement. Readings are best taken with clean, slightly damp feet.
• Stand still and remain on the platform until the complete readout is displayed (the unit stops displaying moving “0”).
• According to the current readings, the system’s algorithm matches the data to the most similar User ID record.
• If the system is unable to identify the User ID, the measurement data will be displayed for about 6 seconds before the device powers off automatically.
• If the system can match the data with users with similar records, each User ID will blink in turn. Single-press the “Set” button to select the right user. The measured data will automatically be logged into the selected User ID and displayed on the screen.

Replacing The Batteries

When the “Lo” symbol appears, it is indicative of a low battery. The device will power off automatically after 4 seconds if the battery is drained. Kindly replace all four batteries at once, ensuring old batteries are not installed with new ones; and all batteries are of the same capacity. Worn batteries are hazardous waste.

Do NOT dispose of them with household garbage. Kindly refer to local ordinances and regulations on the disposal of worn batteries and scrap devices. If this device will not be inactive for a prolonged period, kindly take out the batteries before storing the scale in a cool, dry place.

Battery Replacement Procedure

1. Open the battery compartment on the underside of the scale.
2. Take out the old batteries and dispose of them appropriately.
3. Correctly – in the right polarities, insert the new batteries (x4 AAA) into the battery compartment.
4. The LED screen should light up once the new batteries are properly installed.
5. Close the battery compartment and wait until the digits “0.0” are displayed on the LCD screen.

Body Fat Indicator
The Progress Bar on the LCD screen is also indicative of body fat level. After analysis, the varying length of the bar indicates different levels of body fat. (Kindly refer to “Table of Body Fat Level” for more details.)

Appendix

About Muscle Mass
According to the American College of Sports Medicine (ACSM), lean muscle mass may decrease by nearly 50 percent between age 20 and 90. If you do nothing to maintain muscle mass, you might lose muscle and increase fat. It is also essential to know your muscle mass percentage during weight reduction. When at rest, the body burns approximately 110 additional calories for each kilo of muscle gained. The benefits of gaining muscle mass include:

1. Reversing the decline in strength, bone density, and muscle mass associated with aging.
2. Maintenance of flexible joints.
3. Guided weight reduction when combined with a healthy diet.

Regular exercise and a balanced diet can help maintain healthy bones. Like the muscle, the bone is a living tissue that can respond to exercise by becoming stronger. For most people, bone mass peaks in their thirties and then declines. Regular exercise can help prevent this. Calcium and vitamin D contribute to healthy bones. Some good sources of these nutrients are dairy products, green leafy vegetables, and fish. The bone mass readings given by this product are estimates of the amount of bone in your body. Kindly note; that those with osteoporosis or low bone densities may not get accurate estimations. If you have any concerns regarding your bones, please consult your doctor, as soon as possible.
