+### Error Codes
+
+The following error codes will be displayed if one of the dependancies is not met.
+
+* E-STEPS - no pedomintor widget has been installed, please install the widpedom or the activepedom widgets
+* E-CALIB - no compass calibration data was found, see 'Compass Calibration'
+* E-FW    - require firmware 2v08.187 or later to detect gps and compass power status
+
 ### Issues
 
 * GPS time display shows GMT and not BST, needs localising
 * Occassional buzzing after 2-3 days of use, seems to disappear after
   a reset to the launcher menu. Needs investigation
-* Need to gracefully handle incorrect firmware
-* Need to gracefully handle missing compass calibration data
-* Need to gracefully handle missing steps widget
