Why is the CT72 not reading
the employee's finger when
enrolling or punching?
No matter how the employee
places their finger on the CT72
sensor, it will not read the
fingerprint.
The employee has injured their
finger and the CT72 sensor will
not read their fingerprint.
Why do the employee badges
sometimes register a punch
while in the badge rack?
What does the blinking light in
the small rectangular opening
on the front of the clock mean?
24  Troubleshooting the CT Series
Make sure:
-The employee's finger is
correctly placed on the sensor.
-If the finger is too dry, breathe
on it or have the employee
touch their finger to their
forehead or side of their nose
and then place the finger on
the sensor.
-If the finger is too moist, have
the employee rub their finger
on their pants or sleeve and
then place the finger on the
sensor.
Try re-enrolling the employee's
finger, if that doesn't work enroll
a different finger.
Enroll a different finger for the
employee.
The clock uses an internal
antenna. Make sure badges are
kept 6" away from the clock
when not in use to avoid
accidental badge reads.
This blinking light represents
the connection to the wired
network (LAN).
