INSTALLATION
2.1.1 Installing the Remote Kit (KRK-14H, KRK-15B)
The KRK-14H and KRK-15B remote kit is used to remotely oper-
ate the NX-5700/5800 series transceiver.
The KRK-14H is connected to the NX-5700/5800 or KCH-19 op-
eration panel with the KCT-71 remote control cable.
The KRK-15B is connected to the NX-5700/5800 RF Deck with
the KCT-71.
Note:
The KRK-14H has the common firmware of the NX-5700/
5800.
When turning the transceiver power ON in the state from which
the firmware version of the NX-5700/5800 RF Deck and KRK-
14H is different, the firmware programming mode will start up
automatically, and "FIRMWARE PROG" is displayed on the
LCD.
In this case, rewrite the newer version firmware.
The firmware is written into the NX-5700/5800 RF Deck and
KRK-14H at the same time.
