IMPORTANT!
Make a backup file of the transceiver's settings, such as stored memory channels, filter settings, to the SD
card or USB flash drive before updating the firmware.
The CPU will be automatically reset when the firmware update is done, the transceiver's memory contents
will be cleared and ALL settings will be returned to their default settings.

USB SEND/Keying Inhibit at Connection
Turn ON the timer to prevent unintentional SEND or
Keying signal transmission if the USB driver version is
not the latest one, under the following conditions.
• When connecting a PC to the IC-7850/IC-7851 using a
USB cable.
• When a virtual serial port communication has been
established.
• While the IC-7850/IC-7851 and a PC are connected
using a USB cable, or when starting up the PC or
connecting or disconnecting a USB device to or from
the PC.
• OFF: The IC-7850/IC-7851 transmits the SEND or
Keying signal right after a PC or USB device
is connected.
• ON: The IC-IC-7850/IC-7851 transmits after a few
seconds have passed, to prevent unintentional
transmission.
L If you change this setting to "OFF," update the
transceiver's USB driver and make sure the SEND or
Keying signal will not be unintentionally transmitted.
