Frequently Asked Questions - SFW123TTC SentrySafe

How do I open the safe if the batteries are low?
Use the auxiliary battery: remove the silicone cap on the side of the lock, insert a 9V battery, activate the keypad, enter your code, then turn the handle. Then replace the main batteries with 4 AAA alkaline batteries.
How do I activate the safe alarm?
Close and lock the door, then touch the keypad to activate it. Enter the sequence '0' - 'PROG' - '9'. The alarm indicator will flash every 10 seconds to confirm activation.
What if I forgot my user code?
The 5-digit factory code, printed on the back of the owner's guide, always works and cannot be changed. Use it to open the safe, then reprogram a new user code.
How do I adjust the alarm sensitivity?
Activate the keypad, enter '0' - 'PROG' - 'PROG' - (factory code) OR (user code) - '3', then choose a level from 0 (least sensitive) to 5 (most sensitive). Confirm.
Why does the handle turn without opening the door?
This is a force protection: the handle slips if too much force is applied. Turn it gently in the opposite direction until you hear a click, then try again normally.
Can I store jewelry or watches in the safe?
Yes, but place them in an airtight container to protect them from humidity. The included desiccant must be kept and replaced every 6 months.
How do I delete a user code?
Activate the keypad, enter 'PROG' - (factory code), wait for the indicator to flash, then enter '00000'. The code is deleted (no visual confirmation, test it).
What does the red flashing 3 times mean?
This indicates the entered code is incorrect. Check and re-enter it. If the programmable code does not work, use the factory code.
Is the safe water resistant?
Yes, it is equipped with a sealing gasket, but the desiccant is necessary to prevent internal humidity buildup. Do not store items directly without protection.
How do I set the alarm duration?
Activate the keypad, enter '0' - 'PROG' - 'PROG' - (factory code) OR (user code) - '4', then enter a number from 01 to 99 minutes. Confirm.
