2ABREIVF-BT04Distance monitoring bracelet

USER MANUAL BT01/BT02/BT03/BT04 JOHN LEE COMPANY NAME @COPYRIGHT 2020 IN CHINA The Distance Monitoring Bracelet (alias name such as distance Reminder, Protector, Smart Distance Alert, Social Distance Reminder, Smart Wristband, Distance Trace Bracelet, Smart Distance Keeper, Keyfob Distance Reminder, Necklet Distance Reminder) especially designed to avoid closing social contact from anyone to the others, future function of the device is for system Integrators to develop cloud application for the civilian in order to guarantee and movement traceability of civilian (most are workers, employees & students) staying at a safe social distance from any two of closing peoples and away from infector of disease. Basing on LED light indicator and vibration notice, any of two closing peoples will be reminded to each other in real time. Key point is to instruct people move away from potential disease and traceability in the future. NOTE: This document is constantly updated and is therefore subject to change. Product Feature  RealTime Distance Monitor/track within a radius of 200cm and detection angle more than 100degree auto‐detection of closing contact (depends on configurable)  Operating Frequency: 2.41Ghz ‐ Bluetooth Low Energy BLE5, 5dBm maximum Power  Detection Accuracy: ± 30cm (depends on environment)  Detection Interval: 1.5 second in default (configurable 1 ‐30)  Detection Threshold: 83 dBm in default (configurable 70‐96)  Dimension(BT01): 38(L)*30(W)*13mm(H) (body)/260(L)*36(W)*16.6mm(H) with strap  Dimension(BT02‐BT04): 47(L)*18(W)*11mm(H) without wristband  Net Weight: 38.3g/BT01, 20g/BT02‐BT03, 28g/BT04  Color: Black in default (Blue/Orange/others is optional on above picture)  Material: PC + Silicon TPE  Power Consumption: Continue working 40days & replaceable CR2477 battery Continue working 5‐7 days & rechargeable lithium battery 90mA  Indicator: Closing Alarm, Power & Recharge with LED light & Vibrator (Beeper is optional)  Temperature Measurement: 35 0 C‐42 0 C (Model BT03 or above only)  Display: 0.42 inch OLED (Model BT04 or above only)  PNP device without apps or with special infrastructure and Apps  Upto 10240 Records of closing contact can be saved and uploaded via APP/Gateway infrastructure. Quick Operation STEP 1: Switch on Battery Supply (BT01 required only) There is 2 options either to remove the protection film from battery or open housing and correct battery installation  1st option: Remove Transparent Protection/Isolation Film from the corner gap of device (nearby “” button). The function of Isolation film is to not drain down battery life during logistics before use.  2nd option: Open device housing and correct the battery placement from up to down, refer to the “Battery Operation” Note: While the battery is powered to the device, LED light from device will blink light for 5seconds immediately and run in closing detection automatically to track the potential closing device and record into its memory.. STEP 2: Power on Device For a new device, keep touching “” Button for 8 seconds to switch on bracelet and ensure it will blink LED light and vibrating for 2 or 3 times. STEP 3: Device Registration Each device will be bounded with a NickName, LoginID(Personal ID or MAC address) and password (Default is 123456) then assigned to the end customer. This process can be made by your administrator, or do it by yourself via our ClientAPP as below APP Instruction mentioned. Without registration of each bracelet, closing data will just record MAC address of the device. STEP 4: Wearing Device & Follow Movement Instruction Away from Closing Contact Every bracelet was with enough battery life and keep working properly for your employees, workers, or students, instruct people to away from others during working / studying STEP 5: Uploading Closing Contact Via Gateway Since each bracelet will record no more than 10240 closing contacts, the suggestion is to upload data every time from Gateway entrance/exit as below GatewayAPP mentioned Final STEP 6: Query Closing Contact Any people allow to check their closing contact by ClientApp or Platform. Movement Instruction & Distance Measurement Distance measurement with closing alarms for any 2 closing devices is about 150cm, the closing alarm is LED blinking and vibrating  Prohibited Movement The above specific scene with visual movement (parallel, straight meet, facing meet and line follow straightly) must be prohibited as the movements is with known risky. The device has limited detection accuracy as below signal coverability graph BT01 BT02/03/04 New BT04 with 15.9 transmission A reliable / conformable wearing style is most importance than the others since different wearing has different measurement & detection performance.  Distance Description 1) Social distance must be kept above 1.5meter, otherwise device will alarm from one to the others 2) Safe distance at least 0.5meter as this is minimum requirement. 3) Direct distance should be diagonal distance with 2.0meters +  Standard Movement Measurement (Basing on “Echo Free” Test) Known variant measurement is due to RF noises such as reflection, shadow, resistant and so on, so Standard movement test is recommended in an ECO‐FREE chamber, the alarm distance of measurement is around 1.8m‐1.9meter.  Movement Instruction, remind people away from closing contacts Alarm distance is about 0.5‐2.0meter while People line follow as right picture due to body disturbance occurs for the RF signal Alarm distance is about 0.5‐1.5meter While people stay/walking parallelly Due to body and body size As detection range & angle is influenced by infrastructure reflection, shadow and body disturbance occurs, the detected social distance will be more than 0.3meter variant due to huge man, slim girls and different size of human body. VS Any two movements are walking together closely as below, the alarm distance (social distance) is about 1.9meters Below case, static social distance will be more than …

FCC RF Exposure FCC ID: 2ABREIVF-BT04 Applicant: Xiamen Innov Information Technology Co.,LTD. Exposure category: General population/uncontrolled environment EUT Type: Distance monitoring bracelet Device Type: Portable Device FCC Part 2 §2.1093 Evaluation method According to KDB447498 D01 General RF Exposure Guidance v06 Section 4.3.1 Standalone SAR test exclusion considerations:“ Unless specifically required by the published RF exposure KDB procedures, standalone 1-g head or body and 10-g extremity SAR evaluation for general population exposure conditions, by measurement or numerical simulation, is not required when the corresponding SAR Test Exclusion Threshold condition, listed below, is satisfied. These test exclusion conditions are based on source-based time-averaged maximum conducted output power of the RF channel requiring evaluation, adjusted for tune-up tolerance, and the minimum test separation distance required for the exposure conditions.22 The minimum test separation distance is determined by the smallest distance from the antenna and radiating structures or outer surface of the device, according to the host form factor, exposure conditions and platform requirements, to any part of the body or extremity of a user or bystander (see 5) of section 4.1). To qualify for SAR test exclusion, the test separation distances applied must be fully explained and justified by the operating configurations and exposure conditions of the transmitter and applicable host platform requirements, typically in the SAR measurement or SAR analysis report, according to the required published RF exposure KDB procedures. When no other RF exposure testing or reporting is required, a statement of justification and compliance must be included in the equipment approval, in lieu of the SAR report, to qualify for the SAR test exclusion. When required, the device specific conditions described in the other published RF exposure KDB procedures must be satisfied before applying these SAR test exclusion provisions; for example, handheld PTT two-way radios, handsets, laptops & tablets etc.23 “[(max. power of channel, including tune-up tolerance, mW)/ (min. test separation distance, mm)] · [√f (GHz)]≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR, where: • f (GHz) is the RF channel transmit frequency in GHz • Power and distance are rounded to the nearest mW and mm before calculation • The result is rounded to one decimal place for comparison • 3.0 and 7.5 are referred to as the numeric thresholds in the step 2 below The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm and for transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation distance is <5 mm, a distance of 5 mm according to 5) in section 4.1 is applied to determine SAR test exclusion.
