 DT80 restarted 
 Power loss 
The DT80 lost power, both external and the internal battery. This message may also be displayed if 
the hardware reset button (accessed using a paper clip) is pressed. 
DT80 restarted 
 Safe mode 
A "triple-push" reset was performed (by pressing the hardware reset button three times within 10s), 
which temporarily restores factory settings 
DT80 restarted 
 SW exception 
This indicates a possible problem with the DT80 firmware. Contact dataTaker Technical Support if 
you see this message. 
DT80 restarted 
All mem cleared 
The DT80 lost power, and all internal RAM has been cleared, probably due to the internal Lithium 
memory backup battery being flat. Programs and logged data will not be affected but you will need to 
reset the DT80's time/date. 
Logging Suspended 
If data for one or more schedules cannot be logged for some reason then the DT80 will continue to run the job but it will 
flash the Attn LED and display a message such as the following. Pressing a key will clear the message from the display, 
but the Attn LED will keep flashing until space is made available (e.g. by deleting data or inserting a USB device)

Comments 
 Cannot log 
 Data full 
One or more schedules have been set to "no-overwrite" mode (NOV schedule option), 
and the allocated space is now full 
 Cannot log 
 No USB device 
The "A:" schedule option (log directly to USB device) has been specified, but no USB 
device is inserted. 
User Control 
You can also turn the Attn LED on or off using the SATTN (Set Attention) and CATTN (Clear Attention) commands. 
Alternatively, the 
1WARN channel type (which works in the same way as a digital output channel) may be used. 
For example: 
  RA1S ALARM1(3TT>500)"Meltdown"{SATTN} 
will cause the LED to come on and stay on if the alarm is triggered, and 
RA1S 1CV=(1CV+1)%10 IF(1CV==0){1WARN(R,200)=1} 
will give a 200ms flash every tenth time the schedule is scanned.
