Page purpose:
This page maintains the right half of the security code.
Parameters:

NOTE:
This code must be identical to that used in the associated transmitter.
This three-digit number and the one entered in the
Security Code Part 1 page
are formed into a single six-digit
security code. This code is your security key for this receiver. An identical code must be entered into the
associated transmitter for the audio to be properly decoded.
Enabling this function is useful when sensitive information must not be made public. Standard FM wireless
transmitters can be picked up using scanners and other electronic devices. Unless a Zaxcom receiver is used, even
an uncoded transmitter signal cannot be picked up using a scanner.
The six-digit security code provides a total of 16,777,216 possible choices.
If a Zaxcom receiver has been programmed with a security code, it will also continue to receive an uncoded
transmitter (both ID#0 and ID#1 set to 000). Since the receiver has to check for two possible code situations, a
slight performance penalty may be incurred during long-range reception. To avoid this, it is highly recommended
that both the transmitter and receiver codes be set to 000:000 (uncoded) when high security communication is
not required.
