USING THE IHEALTH WIRELESS SCALE LITE
1. Install the Batteries
Open the battery compartment on the bottom of the Scale and 
install the batteries. 
2. First-time Use
For your first weigh-in, follow these steps to ensure the Scale 
and the app are connected correctly and to synchronize the 
date and time stamp for your next weigh-ins.
Enable the Bluetooth on your mobile device (Settings->Blue-
tooth->On).
Tap the Scale to turn it on. The Bluetooth icon on the Scale will
begin to flash.
Launch the app to initiate the connection. The Bluetooth icon
will light up and stop flashing when a successful connection is 
established. The Scale is now connected and ready for your 
weigh-in.
3. Your Next Weigh-in
Subsequent daily weigh-ins can be taken without being 
connected to your mobile device, as your weight data is stored 
in the Scale and uploaded to the app upon your next connec-
tion. Real-time weight results are viewable in the app if the Scale 
is connected to your mobile device and the app is running when 
your weigh-in occurs. The Scale can store up to 200 weight 
measurements. When the memory is full, any new measure-
ments will overwrite the oldest ones. 
SCALE HANDLING & USAGE
• The iHealth Wireless Scale Lite can measure weights up to 400 lb. 
• For best results, the Scale should be used on a flat, hard surface. 
Soft surfaces such as carpeting or rugs may affect the accuracy of 
your reading.
• The iHealth Wireless Scale Lite has an automatic shutdown 
feature to conserve battery power. The following scenarios will 
cause the Scale to go into automatic shutdown mode: 
º One minute has passed after completion of successful
weigh-in.
º The battery level is too low to capture an accurate weight 
reading.
SOFTWARE UPDATES
From time to time, the Scale's software is updated to enhance 
performance. When a software update is available, a notification 
message will appear in the app. Complete the following steps to 
install the update:
Follow steps 1-3 in the "First-time Use" section.
You will see a notification message in the app asking for
permission to proceed. Select "Yes".
The update will begin to download. You will see a cursor on the
scale display moving from left to right. The scale will display "0.0" 
when the update is complete.
Software Update Troubleshooting
If the software update fails for any reason, you might experience 
one of the following:
1. An error message reading “Er 10” appears in the display area. In
this case, the Scale software will automatically revert to factory 
settings. The Scale will count up to 100 and then back to 0.0. This 
step requires no user action. When the Scale has finished 
counting down to 0.0, repeat Steps 1-2 above to restart the 
software update. 
2. The count up from 1 to 100 freezes and stops progressing. Re-
start the Scale by pressing the “Set” key on the back of the Scale 
next to the battery compartment and hold it for 8 seconds.

SAFETY INFORMATION
Read all of the information in the User Manual and any other 
liter-ature in the box before operating the unit.
1. Please stand on the Scale, keeping as still as possible, until the
result appears on the display.
2. Do not stand on the edge of Scale, as you may fall over or
influence the accuracy of the measurement.
3. Do not use the Scale on a tiled or wet floor, as this may result
in a fall.
4. Make sure the surface of the Scale is clean and dry before
you step onto it, to prevent any slippage.
5. Treat your Scale with care. Do not drop it or jump on it. The
Scale is designed to be stood on; misuse or abuse may break the 
electronic sensors, cause injury, or result in inaccurate measure-
ments.
6. Never immerse the Scale in water. Clean the surface with a
damp cloth.
7. Do not use the Scale on an uneven floor or soft surfaces such as
carpets or rugs while weighing, as doing so may result in 
unreliable measurements.
8. To avoid damage as a result of battery leakage, remove the
batteries if the Scale is not going to be used for 3 months or 
more.
9. Do not use or store near strong magnetic fields, such as micro-
wave ovens.
10. The Scale may not perform accurately if it is stored or used
outside the specified temperature and humidity ranges quoted 
above under “Specifications.”

radio frequency energy and, if not installed and used in 
accordance with the instructions, may cause harmful interfer-
ence to radio communications. However, there is no guarantee 
that interference will not occur in a particular installation. If this 
equipment does cause harmful interference to radio or 
television reception, which can be determined by turning the
