Near Intersection of I-35 & I-90 Southern Mn. | Sounds like the keypad sticker is incorrect for your 500. The keypads for the various Trimble products are the same but a different sticker is used for different models.
The one for the 500 should have OK on the upper right with the Up arrow as the middle key on the right and the Down arrow key as the lower key on the right. The Left keys should be I, II, III. |
