• When registering an addi tional keyfob, 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.
• 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 memo ry is input, the same ID code can be entered. The
code is counted as an additional code.
1. Touch “MULTI REMOTE ENT”.
2. Touch “WORK SUPPORT”.
3. The items are shown on the figure can be set up. • “REMO CONT ID CONFIR”
Use this mode to confirm if a keyfob ID code is registered or not.
• “REMO CONT ID REGIST” Use this mode to register a keyfob ID code.
NOTE:
Register the ID code when keyfob or BCM is replaced, or when additional keyfob is required.
• “REMO CONT ID ERASUR”
Use this mode to erase a keyfob ID code.
