ZIMO decoders contain an EPROM which stores software that determines its characteristics and functions. The software version can be read out form CV #7 

and #65. The current version may not yet be capable of all the functions mentioned in this manual. As with other computer programs, it is also not possible for 
the manufacturer to thoroughly test this software with all the numerous possible applications. Installing new software versions later can add new functions or cor-
rect recognized e

rrors. SW updates can be done by the end user for all ZIMO decoders since production date October 2004, see chapter “Software Update”! 

Software updates are available at no charge if performed by the end user (except for the purchase of a programming module); Updates and/or upgrades per-
formed by ZIMO are not considered a warranty repair and are at the expense of the customer. The warranty covers hardware damage exclusively, provided such 
damage is not caused by the user or other equipment connected to the decoder. For update versions, se
