I also use the feature of a hold down key. 'i' key alone is used for local help and if held long enough the standard info mode starts with a password prompt. We use the 'zero' key, held for 5 seconds to activate a setup mode. Do not wish to allow a random key press to enter mode. Can Remote Access be changed. We have just started dialog with Unitronics vendor in USA to use Remote Access on product interface to jobsites. Without this feature Remote Access software is not a tool to consider.
