Not used my Kewtec KT77 since it was recertified in January. Switched on on Wednesday to be told it needed a service! How do I reset? If I leave it on it clears in 30 minutes. If I switch off and switch on it starts with no problems.

I would take it back and complain. The 'service' warning should have been reset when it went for calibration. One thought, is the date backup battery ok? I believe the Kewtech kt77 is based on the Seaward Supernova firmware and they can throw a wobbly if the back up battery is low or dead.
