How can I upgrade 2400 to 2400H?

This is a fairly simple procedure.  You would need to send your current ESU-2400 to our service center.  We would replace the boards needed to upgrade to the newer, more powerful ESU-2400H.  If you would like to obtain a formal quote, contact me at koday@bcgroupintl.com and provide your complete contact information along with the serial number of the unit in question.
