The SC-848W provides three separate Countdown Timer options: 
 
Countdown and Count up: Counts down from the preset time and then counts up.  
Loop Timer: Automatically repeats the preset time up to 99 times. 
Training Timers: Input up to nine separate preset times to countdown in sequence. 
 
Upon entering the TIMER mode, you may select the option you seek by pressing and 
holding “B” for three (3) seconds.  Each option will appear with the respective indicators 
(refer to Part 1).   
 

Countdown and Count up:

 TR appears in the top row of the display. 

To set: Press and hold “F” for 2-3 seconds.  SET appears flashing and Countdown Hours 
flash.  Press “A” to advance hours. Repeat this process for Minutes and Seconds.  Press 
“F” again to exit setting. 
 
Start the Countdown by pressing “A”.  Time will count down in 1/100 second format. 
You may stop and restart time counting down by pressing “A” when necessary.  Upon 
completion, the timer will sound a signal and begin counting time up as a stopwatch.  
Stop the Stopwatch by pressing “A” twice and then holding “B” for three seconds to reset 
to the Preset time and sequence into the next option. 
 

Loop Timer: 

(000) and TR appear in the top row as does the loop indicator.  Set the 

Preset as instructed in above paragraph.  Press “A” to begin the Countdown Timer.  Upon 
completion of the first loop sequence, press “A” twice to stop the time counting down. 
After countdown time is complete, a signal will sound and the SC-848W will 
immediately begin the countdown sequence again.  Press and hold “B” for three seconds 
to reset the timer and sequence to the next option. 
 
The number of completed times is recorded in the Counter on the top row, up to 99. 
 

Training Timers:  

(000) / 01  TR 1 appears in the top row and the Repeat  (down 

arrows) indicator.  Press “F” to select from timers 1 though 9.  You may preset up to 9 
separate times (channels) which will countdown sequentially.  Once selected, set the 
preset time by pressing and holding “F” for 2-3 seconds.  TR and the timer number (for 
example, “3”) begin to flash.  Advance to the timer number by pressing “A”. 
 
Press “B” again and Hours begin to flash.  Advance hours by pressing “A”.  Repeat this 
sequence for Minutes and Seconds.  Once the time is entered, you may select another 
timer number to set or exit the setting sequence by pressing “F”.
