Finger ID Sensor Cleaning Instructions
Finger ID Sensor Cleaning
Instructions
The following instructions walk you through cleaning the finger ID sen-
sor on your IQ 1000, V800 or V850 time clock. Although maintenance
and handling requirements for the sensor are few in number, observance
of a few basics will help to ensure a high level of performance over the
life of the sensor.
Cleaning the Finger ID Sensor
Oily deposits from your finger accumulate on the surface of the tem-
plate sensor after repeated use. These deposits can inhibit the function-
ality of the sensor. It is recommended that the sensor be cleaned at least
once per week, but it should also be cleaned anytime an oily residue is
visible on the sensor surface.
Use rubbing alcohol and a clean cotton cloth or tissue paper to remove
oily deposits. Do not use a soiled cloth or tissue paper to clean the sen-
sor. A clean cotton cloth or tissue paper will absorb the deposits, but a
soiled cloth will smear deposits over the sensor surface. Rubbing alco-
hol is the preferred cleaning solution because it absorbs the oily residue
and evaporates quickly.
The use of nylon brushes or scouring pads, abrasive cleaning fluids or
powders, or steel wool is
not
recommended.
