Initial Start-Up

General Instructions

The Kogan smart scale applies BIA (Bio-impedance Analysis) technology. A small amount of weak current flows through the human body so as to detect the bio-impedence and estimate body fat. The electric current is so small as to not be felt by the user. BIA technology is safe, non-invasive, toxin-free and harmless. The current used is less than 1mA, however anyone wearing any form of electronic medical implant such as a pacemaker must avoid using this device.

Inserting the Batteries

1. Open the battery door in the back of the scale.
2. Insert the batteries (4 x 1.5V AAA) into the battery compartment, making note of the polarity indicators marked inside the compartment.
3. The digits "8888" will be shown on the LCD.
4. Close the battery door and wait until the digits "0.0lb" are shown on the LCD.

Caution

• When the [Low Battery Symbol] appears, the device will power off. You should then replace the batteries with a new set of batteries. Please replace all four batteries at the same time. Do NOT mix old batteries with new ones.
• Worn out batteries are classified as hazardous waste. Do NOT dispose of them in the household garbage.
• If you do not intend to use the scales for a prolonged period of time, please remove the batteries before storing.

Measuring

Daily Measurement

The scale will turn on as soon as you step onto the platform in bare feet.

Stand still and keep full contact with the [Electrode]s. The weight unit will flash, then the weight measurement will be locked. When the moving "o" animation stops, the LCD will display the weight and body fat measurement.

When the scale is successfully paired with the smartphone and the Bluetooth is turned on, the data transfer will begin automatically. (Please refer to 'Data Transmission' below for more details)

Data Management

Data Transmission

With the scales successfully paired up with your smartphone, measurement data will be automatically transmitted to your mobile via Bluetooth.

The ✔️ symbol will disappear once the data transfer has complete successfully. You may then check your health data on your phone.

If the data transmission fails, the ? symbol will remain on the screen. The pending data will be stored in the scale and transmitted to your smartphone when the next measurement is taken.

Caution

• Interference may occur in the vicinity of equipment marked with the ? symbol.
• To enable the data transmission function, the product should be paired to a Bluetooth 4.0 device.

How to avoid possible interference?

1. The range between the scales and the Bluetooth device should be reasonably close, anywhere between 1 and 10 metres. Please ensure that there are no objects between the scale and the Bluetooth device.
2. To avoid interference, other wireless/Bluetooth enabled devices should be kept away from the scales while transmission is taking place.

Health Tips - About Body Fat

Fat is essential to the human body. It not only stores energy and protects viscera, but it also regulates body temperature and maintains the normal physiological function of the human body. However, too much body fat is harmful to the human body, as it can lead to fatty liver, diabetes, coronary heart disease etc...

Self-measuring and self-monitoring your body fat levels is beneficial to your health. Body fat levels cannot be judged simply by weight.

EMC Guidance

Table 4 – Guidance and manufacturer's declaration – electromagnetic immunity for all ME equipment and ME systems that are NOT life supporting.

Note 1: At 80MHz and 800MHz, the higher frequency range applies.

Note 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.

a) Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the device is used exceeds the applicable RF compliance level above, the device should be observed to verify normal operation. If abnormal operations are observed, additional measures may be necessary, such as re-orienting or relocating the device.

b) Over the frequency range 150kHz to 80MHz, field strengths should be less than [V1] V/m.
