just did mine so...
turn it on..
get the flashing insert test stick icon
press the on/off switch for 3 seconds
screen should read ON
use on/off switch to toggle through
the one that say 2069 is the year use arrow keys to move down
then n/off switch takes you to day month or month date on/off switch to choose which you want
then set day and month with arrows
after that on/off switch to set time
not exactly intuitive.. the year had me foxed for a few seconds..
have fun!
