14 Using the Encrypted Transmission Function
Using the
Encrypted
Transmission
Function
To prevent hacking of the signal, the
transmitter scrambles the signal during
transmission. To use this function, select
one of the following encrypted transmission
modes:
Secure key mode: An encryption key
that is automatically generated by the
transmitter is used by both the transmitter
and receiver in this one-to-one encrypted
transmission method.
Password mode: You choose a
password of up to eight characters that can
be set for multiple transmitters and
receivers. This enables encrypted
transmission within a group.
Make sure the same mode is set on the
transmitter and receiver.
Using secure key mode
(SECURE KEY)
Use this mode for one-to-one encrypted
transmission between one transmitter and
one receiver.
An encryption key that cannot be read from
the outside is automatically generated by
the transmitter. This key is transmitted to
the receiver through a USB connection or
the RF REMOTE function, enabling
encrypted transmission to take place.
The encryption key used by the transmitter
and receiver is newly generated for each
key transmission, resulting in highly secure
communication.
The encryption key used between the
transmitter and the receiver is saved when
the power is turned off, so the encrypted
transmission can be resumed the next time
the power is turned on.
