Dual user mode requires two different combinations to open the lock, entered within two minutes of each other. Select dual user mode by pressing the module button for about one second when the LED next to the dual user icon is blinking. The red and yellow LEDs will begin to blink, indicating that you should begin entering the existing combination(s). The lock will emit six beeps and then two beeps as you begin to dial. The six beeps indicate the lock is in a state to change operating mode, and the two beeps indicate that dual user mode is selected. If your lock is currently in dual user mode, both existing combinations will have to be entered. This is a security feature.
