Changing Settings on an Oregon to Show British Grid Reference

To change the settings on the Oregon® handheld GPS unit do the following:

1. From the main screen select Setup
2. Select Position Format
3. Select the Position Format at the top of the screen and select British Grid from the list.

The entry under Map Datum should now state Ord Srvy GB and the entry under Map Spheroid will state Airy. The device will now give you a 10 figure grid reference for use in conjunction with an Ordnance Survey map. This will only change the setting in the current profile; if you need this in a different profile then you will need to repeat this process in the chosen profile.
