Discrete codes: Versions of toggle codes that only perform
one function. Some examples would be "POWER ON" and
"POWER OFF" or "VCR," "TUNER" and "DVD" receiver
inputs. These types of signals are most often used to ensure
your home theater components stay completely in sync for
powering on and off and changing device inputs. Some of
the preprogrammed codes in the MX-600 contain discrete
codes. If your original remote contains discrete codes,
these can be taught to the MX-600 as well.
Device: The MX-600 remote control is capable of
controlling a certain number of devices, or pieces of

DVD players, receivers or VCRs. Some devices, such as
receivers or dual-cassette decks, may be treated by some
remotes as more than one device. Also known as
components.
Firmware: Indicates the programming software stored on
the remote control. The MX-600 remote can have its
firmware flashed (upgraded) to a newer version.
Frequencies: The range of infrared carrier frequencies that
a remote control is capable of learning or controlling. Most
remotes operate between 30 and 60kHz, however some use
higher and are thus known as high frequency.
The MX-600 operates and can learn frequencies between
10 kHz and 100kHz.
Hard buttons: Refers to all physical (mechanical) buttons
on a remote control.
High frequency: Indicates an infrared system that employs
