There is a sticker located on the side cover of the validator. The sticker has the serial number, model, version, and date of manufacture of your validator. In case the eprom has been changed in the validator and the sticker wasn’t updated, on HVX and XE validators; with the power ON, turn all of the dip switches to the OFF position, then turn ON switches (in this order) 5, 4, and 1. The display will flash 3 numbers; this is the version installed in the validator.
