CHAPTER 7 - MAINTENANCE AND
CLEANING
CHAPTER OVERVIEW
This chapter explains how to replace and calibrate the fingerprint sensor module, and
how to clean the device sensor.
7.1 MAINTENANCE AND CLEANING
The V-Station 4G and V-Flex 4G devices require very little in the way of daily
maintenance except for occasional cleaning and disinfecting. The V-Station 4G and V-
Flex 4G devices feature field-replaceable sensors.
7.1.1 FIELD MAINTENANCE
V-Station 4G and V-Flex 4G fingerprint sensors can be replaced quickly and easily in
the field. The following sections explain in detail the steps required to replace a sensor.
7.1.1.1 DISARMING THE TAMPER PROTECTION
The Tamper Switch is a momentary push-button switch on the back of the device within
the I/O cable interface pocket.
The tamper protection feature allows the device to sound an audio alert, flash LEDs,
send a pre-defined Wiegand string to the control panel, or disable biometrics if the
tam-per switch is triggered.
