You may update the current CU-311 system via the BHT in the following two processes.
(1) Download a CU-311 system reconfig file to the BHT from the host PC

BHT's downloading function—the DOWNLOAD menu or FTP MENU.

"Options for Communications" dialog box beforehand.
(2) Update the current CU-311 system
Place the BHT on the CU-311 and use the CU-311 system updating menu (CU-F/W MODIFY) to update
the current CU system. (For the detailed procedure, refer to Section 2.5.3, [13.2].)
During updating, the POWER LED on the CU-311 will flash. (For details, refer to Section 5.6.1.)
During updating, do not remove the BHT from the CU-311 or turn the BHT off. Doing so will
cause a CU-311 system updating error, making the CU-311 wait for retry.
To recover from such status, carry out the updating procedure again or restart the CU-311.
If the CU-311 has been turned off during updating, restarting it will run either the old CU-311 system
or updated one. You may check which system is running on the CU INFORMATION screen given in
Section 2.5.3, [ 6 ].
The latest CU-311 system reconfig file can be downloaded from our Web site.
