KEYPAD FUNCTIONS

The 3850 timer utilizes a second function keypad; 

functions printed in white operate when pressed; 

functions printed in yellow require the ‘SHIFT’ 

button to be pressed two seconds before the desired 

second function yellow key is pressed.

The following defines the keypad key 

functionality:

Each function is coded for which modes it is 

available in as follows:

 

Manual

 mode  

 

Hard wired

 mode  

 T-Link 

Wireless

 mode  

KEY 1 

 

Pressing 1 COUNT will allow the timer to go 

into countdown mode:  [EntEr] [StArt] [XX] dis-

plays; enter the number of minutes (01 to 99) and 

press # ENTER. The display will show [Count] 

[XX.XX] representing minutes and seconds re-

maining.  Press [1] again to stop the count; [StoP] 

[Count] will briefly display and the screen will 

blank.

KEY 2  

 

The 2 IGNORE key will stop and give no time 

for the currently running timer.

KEY 3  

 

  Pressing the 

[3]

 key will manually start a 

timer.  This is the same function as breaking the 

start beam.  If all four timers are counting and the 

[3]

 key is pressed, the bottom timer will be lost 

and a new timer will be started at the top of the 

display.  Since this is manual mode, the operator 

has full control of the timer starting function.  This 

key is enabled when the Status Display indicates

 

[OFF]

.

KEY 5  

  If a timer is inadvertently stopped by a worker 

running through the finish line or manually stopped 

by pressing the Manual Stop or Off Course keys, 

the timer can be restored and counting with the 

correct elapsed time using the 

[5] 

Continue  key.  

The most recently stopped timer is restarted and 

updated from a backup timer internally maintained 

by the Timer AC4.  The timer is restarted and 

updated with the correct elapsed time.  A timer 

can be stopped and restarted an unlimited number 

of times.
