On top of your EZ-Guide 250 & 500 display there are two barcode stickers. On the stickers next to the Trimble logo you will find the Serial Number of your EZ-Guide 250 or 500. (See image below)
Please note your Serial Number before calling our support department 088-818 0 818 (NL) , 011 599 566 (BE) or 029 239 715 959 (DE). This significantly shortens the waiting time for you and other costumers. Thanks in advance for your cooperation
