TIMER OPERATION

 

 

When the unit is configured to count up a user-preset stopping time may be entered, but is optional.  
If a user-preset stopping time is entered and the timer is started the timer  will  begin  counting  up  from 
zero  and  stop  at  the  user-preset  stopping  time.    If  a  user-preset stopping time isn’t entered and the 
timer is started the timer will begin counting up from zero and will count up indefinitely until it is stopped. 
 
When the unit is configured to count down a user-preset starting time must be entered.  Once a user-
preset starting time is entered and the timer is started, the timer will begin counting down from the 

user-preset time to zero. 

 

User-preset stopping times (for count up mode) and user-preset starting time (for count down mode) 
are entered using the same procedure. 
 

To enter user-preset starting/stopping times: 

 

1.  Press and hold the SET CLOCK key until the display clears. 
 
2.  Using the numeric keypad, enter the desired starting/stopping time.
 
3.  Press the NEXT key followed by the NEW GAME key to set the new time.
