 Bluetooth Communication Function
HL858DC features a built-in Bluetooth Communication function,
which enables the device automatically transmit measuring results to
paired Bluetooth device. When connection established, BPM would
transmit memory data such as Measure Date, Systolic Pressure,
Diastolic Pressure and Pulse Rate to the Bluetooth device.
HL858DC also supports user proceed with Bluetooth device to
perform Date/Time Synchronization, Measurement Synchronization,
User Selection Synchronization, History Data Transmission, and
Memory Delete.
If paired Bluetooth device is not working or is not within RF range of
this device, the measuring results will be stored in the blood pressure
monitor's memory. For more details, please refer to “Bluetooth
Communication” page.
Bluetooth compatibility with blood pressure monitor for
Bluetooth-enabled device is:
 Bluetooth 4.0 for Android 4.3 or above,
 Bluetooth 4.0 for iOS 7.0 or above

*Note ！
 HL858DC is subject to and complies with electromagnetic compatibility
(EMC) standard of EN 60601-1-2, EN 301 489-1, EN 301 489-17, EN 300
328 and U.S. federal guidelines, Part 15 of the FCC (Federal
Communications Commission) rules for devices with RF capability. These
guidelines help ensure that your device will not affect the operation of
other nearby devices. Additionally, other devices should not affect the use
of your device.
 Other wireless devices that are in use nearby, such as a cell or mobile
phone, or a wireless network, may prevent or delay the transmission of
data from your device to paired Bluetooth device. Moving away from the
source of the interference or turning off these devices to resolve the
problem.
 Make sure HL858DC and paired Bluetooth device are within acceptable
distance (no more than 10 meters) with each other. If not, put them closer.
 If you plan to transmit test results to paired Bluetooth device, be sure to
select User 1, 2, or 3 before measurements, in case other people’s results
may be transmitted to your paired Bluetooth device or included in your
