Operating Instructions

This section outlines the basic operation of the YOSEC E-638 digital keypad lock. Ensure the lock is properly installed and powered before proceeding.

Opening the Safe

1. Enter your valid digital pin code (typically 6-8 digits).
2. Press the "#" key to confirm the entry.
3. If the code is correct, you will hear a confirmation beep, and the lock will disengage, allowing you to turn the safe handle and open the door.
4. If an incorrect code is entered, an error indication (e.g., red light, error beep) will occur. Wait a few seconds before re-entering the code.

Setting/Changing User Codes

The YOSEC E-638 supports two distinct user codes. The exact procedure for setting or changing codes may vary slightly depending on the specific safe model it is integrated with. Consult your safe's original manual for precise instructions if available. A common procedure is as follows:

1. With the safe door open and the lock disengaged, locate the programming button on the internal control board (if applicable) or follow the keypad sequence for programming.
2. Enter the existing master code or a default programming code (refer to your safe's manual).
3. Follow the prompts (e.g., indicator lights, beeps) to enter the new 6-8 digit user code.
4. Re-enter the new code to confirm.
5. Test the new code multiple times with the safe door open before closing it.

Note: If you forget your code, you may need to use an override key (if your safe has one) or contact a professional locksmith for assistance.

Battery Replacement

The YOSEC E-638 lock requires one 9V alkaline battery for operation. When the battery power is low, the keypad may emit a warning signal (e.g., a series of beeps or a flashing light) during operation.

1. Open the Safe: Always replace the battery with the safe door open and unlocked to prevent lockout.
2. Locate Battery Compartment: The 9V battery compartment is typically located on the underside of the keypad unit or on the internal control board.
3. Remove Old Battery: Carefully disconnect and remove the old 9V battery.
4. Insert New Battery: Connect a new, high-quality 9V alkaline battery, ensuring correct polarity.
5. Test: After replacing the battery, test the lock's functionality by entering your code several times before closing the safe door.

It is recommended to replace the battery annually or immediately upon low battery warning to ensure reliable operation.

Troubleshooting

Maintenance

• Cleaning: Wipe the keypad surface with a soft, dry cloth. Avoid abrasive cleaners or solvents.
• Battery: Replace the 9V battery annually or as soon as a low battery warning is indicated.
