As of the security function, even the wireless function is normal, there may be the case that only UNLOCK opera-
tion will not work.

is unlocked by unlock operation performed once.
Normal


Operative distance may differ according to
an operator, the way of holding the transmitter
or position.

Because weak electric wave is used, when
there is strong wave or noise in the used
frequency, operation distance might be
shortened.
No Yes
