The keypad is made up of numerical and function keys that are used to control the information

that is either entered or shown on the displays. The numerical keys 0-9 are used only to enter new times.

The function keys A-F are used to control different functions of the unit.

Function Keys A and B

The function keys A and B correspond to displays A and B respectively and are used with the

numerical keys when entering new times. For example to enter a new time into Display A, press the A

key on the key pad. Display A will blank out indicating it is ready to accept a new time. Next use the

numerical keys to enter the new time into the unit, leading zeros do not have to be entered. As the

numbers are entered they will appear on the display indicating that the number was accepted and stored

into memory.

If an error is made while entering, press the appropriate A or B key to erase the last digit. This

can be repeated as many times as necessary until the display is blank.

Function Keys C, D, and E

The function keys C, D, and E are used to select what information is shown on the displays. The

corresponding six red L.E.D.s, two for each key, indicate when lit, what information is being displayed.

For example, if the Dial-Ins are wanted and the First and Second Stage Times are being displayed, the C

key would be pressed to display the Dial-Ins. If the C key was then pressed again the Delay-1 time and

Delay-2 time would replace the Dial-Ins.

Function Key F

The function key F controls three separate functions.

If pressed during a timing cycle, the timing cycle will be cancelled

and the unit will be reset. This constitutes a master reset for the

timing cycle.

If pressed when the unit is not running a timing cycle, the Dial-Ins

will be displayed and set to all zeros, making it ready for new

Dial-Ins before next run.

If the F key is held down while the power is being turned on, the unit

will go into a special test mode. This is described in Testing of the

Unit.
