Appendix A - Tips
Enrollment
Bad enrollments equal bad verification (meaning scores will be too high). The
key to successful verification is education.

Educate the Enrollee on Hand Geometry
Explain enrollment process
Train Enrollee on hand placement
-Practice placing hand on platen
-Make sure hand is flat on platen
-Close finger towards the center of hand
-Fingers need only to gently touch finger pins
Let the enrollee enter in their own ID number during the enrollment pro-
cess, this forces the Enroller to step aside allowing the Enrollee to prop-
erly stand in front of the HandReader helping to eliminate "bad
enrollments"
If an enrollment HandReader is used make sure that it is placed with the
top of the platen 40" off of the floor and not sitting directly on top of a
desk, this will help to eliminate "bad enrollments"
Use shielded cable when installing direct networks. This will help reduce
outside noise interference
Do not lay cabling on top of fluorescent lighting. Make sure the Data
Convertor is plugged in
When starting a network for the first time bring one HandReader up at a
time, this is a very easy way to find out where communication problems
may exist
Use default init string for modem first
Do not set the baud rate of the HandReader down below 9600, unless
communicating in a E series network (metal HandReaders), or risk over-
running buffers
In the init string set the line rate to 14400
Use analog lines (POTS)
Troubleshooting by plugging the HandReader on the fax machine's
phone line
make sure network cable is plugged in to Ethernet card before powering
up the HandReader
Port 3001 must be set on all switches and routers in order to success-
fully communicate over WANs
If the HandReader can be "pinged" but will not communicate with the
software, power down the HandReader and run "ping" again
