Units Page Using your eTrex with a paper map increases the navigation power of both. If you are going to use a map in conjunction with the eTrex, you must select the position format (grid), map datum, map units, and north reference to match the map's units. This is the purpose of the Units Page. Regarding position format, the eTrex allows you to choose from eighteen different grids. The eTrex supports the UTM/UPS and latitude/longitude grids because together they cover the world. Display and Units Pages You can set the backlight to stay On all the time, but watch your battery power! The 'UNITS' Page allows you match the units of the eTrex to the units of a unique paper map you may be using. 33
