Set the clock by following these steps: a). Touch TIME pad. b). Turn rotary knob clockwise until CLOCK appears. c). Touch TIME pad. d). Turn rotary knob in either direction. The time displayed will change in 10-minute increments and indicate AM or PM. Turn the knob in the opposite direction and the display will change in one-minute increments. e). Touch TIME pad. The clock is now set. in some units there is button instead of knob in that case the clock indicating button has to be pressed . This will help.

My eaton viking imperial stove came with the house and no manuals. The timers are digial, how do i set them

press timer (picture with bell) adn cooktime ( picture with what looks like steam above a square) buttons simultaneously while turning adjacent knob clockwise until readout registers current time. Release both buttons and clock is reset.

User manuals are hard to find.
The problem I had was setting the clock on a single Diplomat oven, with no clock button. Here's my solution :

DIPLOMAT OVEN OPERATING INSTRUCTIONS
The Diplomat single oven is controlled by two knobs and a set of buttons along the middle of the control panel.
The left knob sets the temperature of the oven, while the right knob selects the function to be performed, e.g. fan oven, grill, etc.
The buttons along the middle set the cooker clock, the start and end times of cooking, and the “+” and “-“ buttons will increase or decrease the time shown on the cooker’s clock.
PLEASE NOTE THAT THE OVEN WILL NOT OPERATE UNTIL THE CLOCK IS SET.
If there is any interruption to the power supply (including manually switching off at the main switch) the oven will not operate until the clock is reset.
Here’s how to set the clock:
First press simultaneously the first two buttons to the left of the control panel. They are marked as a Bell symbol (Alarm) , and a steaming Cooking Pot (Start of Cooking Time). Then immediately press the plus “+” or minus “-“ buttons to increase or decrease the time displayed. When the desired time has been reached, leave it for a few seconds, and it will remain set at this time. Any further changes to the displayed time will require this procedure to be repeated.
Hope this helps!
