After the system has been set to the prohibition mode, enter the confirmation mode and check that the number of registered keys is 0.

HINT:

• In the confirmation mode, LOCK-UNLOCK operation will occur once for each recognition code that has been registered. For example, if 2 recognition codes have been registered, LOCK-UNLOCK operation will occur twice.
• In the confirmation mode, if no recognition codes have been registered, LOCK-UNLOCK operation will occur 5 times.
