The Silent 610/620 taximeters are programmed using the four push button switches on the front of the
taximeter. When the meter is VACANT, programming of distance calibration, rate, etc., is accomplished by
removing the sealing screw and programming access panel on the front right hand side of the taximeter and
sliding the programming switch SW5 to the left (slide SW5 to the right to return to normal taximeter mode).
This requires breaking the seal wire, if attached.
