Performance Parameters ItemSpecification Power supply4 × AA alkaline batteries Low-battery alarm< 4.75 V Emergency power5 V (Type-C USB) Standby currentApprox. 100 μA KeypadCapacitive touch 12-key (0-9, *, #) Keypad backlightWhite Maximum user capacity100 Virtual passwordUp to 30 digits Operating temperature-20°C ~ 65°C Operating humidity10% ~ 90%, non-condensing ESD immunityContact discharge ±8 kV, air discharge ±15 kV III. Product Functions and Operation When no users are registered, any password with 6 or more digits can unlock the lock. After a password is registered, illegal passwords will not unlock it. If no administrator has been registered in the smart lock, you can use the default administrator password 123456 to enter the add mode. If an administrator has already been registered, you must first verify the administrator before entering the add mode. 1. Installation Settings Input the switch code to select language: Chinese (7100#), English (7101#) 2. Initialization Settings Press and hold the initialization button for 10 seconds; the lock will restore to factory default state. In the initial state, any fingerprint, password with 6 or more digits, or card can unlock the door. The default administrator password is 123456, which becomes invalid automatically after a user is added. 3. Adding Users The first three added users are administrators; subsequent users are ordinary users. The valid password length is 6–10 digits. Enter the same password twice to complete adding a user. 4. Deleting Users The first administrator cannot be deleted. 5. Volume Settings After entering the volume setting operation, only keys 1, 2, 3, and 0 are valid; other keys have no effect. 6. Auto-Lock Settings Enter 5 for 5 seconds, enter 1800 for 1800 seconds (30 minutes). Enter 0 to disable auto-lock. After disabling auto-lock, use the # key to lock the door manually. 7. Aging Mode When the system is in the initial state, enter 9000# to activate aging mode. After an administrator has been registered, aging mode cannot be entered. In aging mode, the system cycles through the aging process; fingerprint, keypad, and card operations are all disabled. Power the device off and on again to exit aging mode. 8. Physical Button Operation (Rear Handle Buttons) SET button: Long press to restore factory settings and clear all data (10 short beeps followed by one long beep indicates success). DIP switch: Enables or disables the remote control function. Pairing button: Long press for 1 second to start or stop remote control pairing (valid only when the DIP switch is in the ON position). 9. Low-Voltage Warning and External Power 1. When the lock battery voltage is too low, the system announces “Please replace the battery” each time it is unlocked. Please replace the battery as soon as possible. 2. If the battery is completely depleted and the lock cannot be operated, use a 5 V USB power supply on the outside for emergency unlocking. 10. Incorrect Trial Alarm After 5 consecutive incorrect user entries, the system locks for 120 seconds. During the lockout period, the system does not respond to any operation. 11. Anti-Peeping Password For example, if the password is 123456, you can enter 96581234562875 – adding some extraneous digits before and after the actual password – and then press # to confirm. The maximum total input length is 20 digits. 12. Mobile App Download and Connection Download the “Tuya Smart” or “Smart Life” app from the app store, or scan the QR code below for download. APP Registration If you do not have an account, you can register or log in via SMS verification code. Tap “Create New Account” to enter the registration page. Follow the prompts to obtain an SMS verification code and set a password. If you already have an account, tap “Log in with existing account”.

FCC ID: 2BV6R-R8 RF Exposure Evaluation According to KDB 447498 D01 General RF Exposure Guidance v06 and part 2.1093，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(s), listed below, is (are) satisfied. For 100 MHz to 6 GHz and test separation distances ≤ 50 mm, the 1-g and 10-g SAR test exclusion thresholds are determined by the following: [(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 Here, The device has been evaluated to meet general RF exposure requirement. The device can be used in portable exposure condition without restriction.
