3.14.12Reflashing/Upgrading Firmware
The FLASH IC is the firmware storage IC. Programming this IC is accomplished using one of the
following input paths:
• Two-wire RS-232 directly from a computer’s serial port to the radio’s rear connector data cable
HKN6160
• Two-wire RS-232 through an HKN6183 programming cable at the control head’s 10-pin
accessory port
For a list of all available programming cables, refer to the table below.
NOTE: FLASH IC replacement is not supported as a field repair option. If the FLASH IC is removed,
the radio cannot be reflashed by a customer or radio depot. This is because the FLASH IC
must be hard-boot loaded at the factory to allow the programming of a unique file.

If you choose to reflash the radio (reflash the IC), DO NOT interrupt the
process; otherwise, you might corrupt the FLASH IC and need advanced
technical support to revive your radio.
