System Components
Remote Key: Features:
• 3 volt lithium battery (commercially available CR 2016)
is used as the power supply for the key transmitters.
• An EEPROM is used to store the key data.
The data is not lost when the battery is re-
placed and initialization is not required.
• The key incorporates an LED that signals the opera-
tor of signal transmitting, key initialization status and
key self test indication.
• The keys are delivered
with a four color label
sheet containing differ-
ent colored labels for
each of the four pos-
sible FZV keys.
This is helpful to differenti-
ate the FZV keys during initialization preventing the pos
sibility of mis-assigning the key ID which would change
the encoded Key Memory functions.
