INSTALLATION
1. Optional Voice Scrambler Function
The optional voice scrambler function can be used by two
methods.
1. Assign this function to any programmable keys by using
the programming software (KPG-59D).
When the programmed key is pressed, the
indicator
appears and optional scrambler function is enabled.
When the programmed key is pressed again, the
indi-
cator disappears and the function is disabled.
2. Assign the optional scrambler function to each channel
by using the programming software (KPG-59D). The op-
tional scrambler function can be used without pressing
the programmed key.
1-1. Scrambler Code Setting
The code can be configured by two methods.
1. Hold down the programmed OPT key to enter the code
setting mode.
Select a new code by pressing [
] or [
] key to
change.
When the programmed key is pressed again, the new
code is stored and exit the code setting mode.
2. Set a code for each channel by using the programming
software (KPG-59D).
2. Option Board
T
erminal
Terminals for mounting the option board are provided at
the center of the TX-RX unit. The table shows the corre-
spondence between the board and terminals. Disconnect
R725 and R778 in TX-RX unit when the voice scrambler
board is attached.
Connect the option board to the connection terminals of
the TX-RX unit.
