3. Using the Static Discharge Cable, press and hold the
plungers on both ends of the cable. This exposes a metal
contact at each end. Touch one contact to the ground
plane and the other to the metallized surface of the pick-
up mat simultaneously to discharge any residual charge
left in the mat (Fig. 4).

Carefully, lift and examine the pickup mat (Fig. 5). It
may not always be possible to see some of the lifted
prints due to low contrast of the dust with the black mat surface. Therefore, examine
the mat using oblique light.
Preserving Lifted Dust Prints
Photograph lifted dust prints and be certain to include a scale. The prints may be lifted
from the pickup mat using Rubber Footprint Lifter No. 647C100 or SIRCHIE’s GELifters
™
.
CAUTION! Attempts to add clear lacquer or similar materials to preserve the print on the lifting mat usually
results in the destruction of lifted prints.
CAUTION! Do not use lifting tape or residue lifters other than those recommended above—it is nearly im
-
possible to separate the device from the mat. Static electricity may also cause the matt to be draw to the tape
prematurely, damaging the lift.
NOTE: Discard mats after the prints are recorded. While it may be possible to clean the mat, wrinkles and
scratches will develop across the surface and interfere with results from subsequent lifts.
Transporting Lifting Mats
If the dust print lift must be transported to the lab for analysis, we recommend the use of ESP908 Dust Print
Evidence Box. Each evidence box is supplied with an evidence label for identification and chain of posses
