NOTE:

If a key fob is lost, the ID code of the lost key fob must be erased to prevent unauthorized use. A specific
ID code can be erased with CONSULT-II. However, when the ID code of a lost key fob is not known, all
controller ID codes should be erased. After all ID codes are erased, the ID codes of all remaining and/or
new key fobs must be re-registered.
To erase all ID codes in memory, register one ID code (key fob) five times. After all ID codes are erased,
the ID codes of all remaining and/or new key fobs must be re-registered.

When registering an additional key fob, the existing ID codes in memory may or may not be erased. If five
ID codes are stored in memory, when an additional code is registered, only the oldest code is erased. If
less than five ID codes are stored in memory, when an additional ID code is registered, the new ID code is
added and no ID codes are erased.

If you need to activate more than two additional new key fobs, repeat the procedure “Additional ID code
entry” for each new key fob.

Entry of maximum five ID codes is allowed. When more than five ID codes are entered, the oldest ID code
will be erased.

Even if same ID code that is already in the memory is input, the same ID code can be entered. The code
is counted as an additional code.
