ID Code Entry Procedure (Cont'd)
EL-291

NOTE:
IIf a remote controller is lost, the ID code of the lost remote
controller must be erased to prevent unauthorized use. A spe-
cific ID code can be erased with CONSULT-II. However, when
the ID code of a lost remote controller is not known, all con-
troller ID codes should be erased. After all ID codes are
erased, the ID codes of all remaining and/or new remote con-
trollers must be re-registered.
To erase all ID codes in memory, register one ID code (remote
controller) four times. After all ID codes are erased, the ID
codes of all remaining and/or new remote controllers must be
re-registered.
IWhen registering an additional remote controller, the existing
ID codes in memory may or may not be erased. If four ID
codes are stored in memory, when an additional code is
registered, only the oldest code is erased. If less than four 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.
IIf you need to activate more than two additional new remote
controllers, repeat the procedure ªAdditional ID code entryº for
each new remote controller.
IEntry of maximum four ID codes is allowed. When more than
four ID codes are entered, the oldest ID code will be erased.
IEven if the 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.
