Chapter 7: Programming 7-21
Active Time (Minutes)
You can program specific lengths of time that your NCR 7870
Scanner/Scale stays on after the last good read. There are four options
in the Active Time parameter: no shut down, shut down after 15
minutes, shut down after 30 minutes, and shut down after 60 minutes.
Select these times using the Hex 0 through Hex 3 tags, respectively.
The default time is 15 minutes. Selecting no shut down results in the
scanner/scale being active all the time.
Note:
NCR suggests that you do not set the Active Time parameter to
“no shut down.” Leaving the laser light on all the time reduces its life
expectancy.
