Changing D-Sub 25-Pin Connector (4 Pin, 5 Pin) Configuration - Kenwood NX-5800 Service Manual

(4) Insert the connector of the module the connector (CN731)
of the TX/RX PCB into.
(5) Pull and remove the release paper while pressing down on
the module with your finger to hold it in place, to attach the
module to the TX/RX PCB.
Note:
• When it is necessary to remove the module, do so by
peeling the module off using your finger, while pulling
it vertically. Do not use a screwdriver or other similar
implement to remove the module; you may inadvert-
ently damage the TX/RX PCB and the module.
• Cushion B cannot be reused. Attach a new cushion B
when you remove the cushion from the module.
(6) Reinstall the cabinet, top packing and shielding plate of the
transceiver.
Note:
• When the KWD-AE30/ KWD-AE31 is installed, select
the "Secure Cryptographic Module" checkbox in the
Product Information of the Programming software
[FPU (Field Programming Unit)], and then set each pa-
rameter.
• If the KWD-AE30/ KWD-AE31 connector is not proper-
ly installed, the TX/RX indicator will blink red or "No
SCM" will appear on the display when the transceiver
power is turned on.
• If the Encryption Key data is not written at the Keyload-
er, or the Encryption Key data is zeroized, "Key Fail"
will appear on the display.
• If the KWD-AE30/ KWD-AE31 is installed in other
transceivers, the Encryption Key data will be forced to
zeroize.
