Using the Calculator While Timing — You can also use the calcu-
lator while timing and it will not interfere with timer operations. To do
this, press [On/C] to exit the timer mode and continue to use calcu-
lator functions. To return to the timer mode, press [Timer 1 (or 2)]
again.
Note: The clock symbol will continue to blink on the display to remind you the timer(s)
is running when in “calculator” mode.
Timer Alarm — After the timer is finished counting up or down, you
will hear an audible alarm. Timer 1 emits a fast beep, Timer 2 a
slow beep. To clear the timer alarm, press either timer key.
Timer Reminder & Alarm — If you are in “calculator” mode and do
not press a key for 11 minutes, the running timer will be displayed
as a reminder. Also, in case you forget the timer, after the timer
alarm goes off it will begin counting up for an additional hour, dis-
playing the “+” sign to remind you of the amount of time elapsed
since the alarm sounded.
Auto Shut-Off — If the timer is left on after the timing period ex-
pires, and you are not using the calculator, the calculator will auto-
matically shut off in:
§ Count-down timer: 1 hour, 11 minutes
§ Count-up timer: 12 hours, 11 minutes
