negative (–) and positive
(+) terminals to the
symbols shown on the
ST-654 housing. The tag
will not work if you install
the battery in the wrong
direction (reversed).
The tag beeps if you install a charged battery. When removing and
replacing a charged battery, you may need to wait a few seconds after
replacing the battery to hear this confirmation beep.

Savi Technology recommends that you mount the SaviTag ST-654 on a flat
surface, with the tag’s longitudinal axis aligned vertically. For optimal radio
communication, place the SaviTag ST-654 as high as possible, safe from
impact (for example, between the ribs of an ISO-type shipping container),
and away from obstructions onthe asset. Recommended mounting locations
for an M3 Container Roll-in/out Platform (CROP) and other mobile assets
are shown in the following pictures.

Replace the battery cover
using a coin or screwdriver.
Turn the battery cover

careful not to overtighten.
Make sure the battery cover
is completely closed and
that it is not cross-threaded.
Dispose of the used battery according to local safety requirements.

You can choose among several mounting methods for SaviTag ST-654,
including using pressure sensitive tape, rivets, or a plastic mounting sleeve.
Whichever mounting method you select, the goal is to prevent accidental
loss of the tag by sudden impact, vibration, or shock during transport. The
fastener you choose often depends on the material from which the asset or
container is constructed and your personal preference.
SaviTag ST-654 includes these recommended mounting fasteners:
◆Rivets
◆Pressure sensitive tape (PST)
You can also use the following alternative fastening methods:
◆Velcro, 3M SJ3550 Dual Lock Reclosable Fastener, 1 inch wide
◆Tie-wraps
◆Twine
◆Screws

If it is not possible or practical to use screws or rivets, you can use pressure
sensitive tape (PST) to attach a SaviTag ST-654. The only brand of PST
that Savi Technology recommends for mounting SaviTags is
3M Corporation’s Automotive Acrylic Plus Attachment Tape.
For ease of installation, during manufacturing Savi installs this PST on the
back of the plastic mounting sleeve. PST mounting kits are also available
for separate purchase.

)LJXUH 6DYL7DJ67IDFWRU\LQVWDOOHG367
Once a mounting sleeve is fastened to an asset, you can leave it on the asset
even after the SaviTag ST-654 is removed so it is available for future use
with other compatible SaviTags. Prior to re-use, visually inspect the
PST-mounted sleeve to make sure it is attached securely. If necessary,
reinstall the sleeve using new PST.

3M Corporation has conducted extensive environmental testing on their
Automotive Acrylic Plus Attachment Tape. In addition, Savi has conducted
its own independent environmental tests of PST using the SaviTag ST-410
as a test platform. The U.S. Army (Tobyhanna Army Depot) has also tested
PST for use on surfaces treated with Chemical Agent Resistant Coating
(CARC). All these tests confirm that PST is an appropriate choice for
mounting SaviTags.
◆Savi Technology successfully conducted the following tests upon
samples of 3M PST:
❖Extreme temperature (–40º to +70º Celsius)
❖Step test (200 pounds applied in shear)
❖Shock (140g or 120 lbs.)
❖Vibration (MIL-STD-810E)
❖Salt fog (MIL-STD-810E)
❖Corrosive liquids
❖Peel test (50 pounds of peel force)
&+$37(5
,QVWDOOLQJ6DYL7DJ67
Savi’s tests confirm the excellent adhesion integrity and reliability
of 3M PST.
◆3M Corporation conducted a longevity test of PST. They found no
significant degradation in the performance of PST even after five years
of service on a test vehicle. As long as the surface is prepared properly,
PST will work reliably for five years or longer. See “Preparing the
Surface for PST Application” on page 18.
◆3M Corporation compared the peel strength of a new roll of PST versus
a roll that had been aged 21 months. In all cases, the aged roll matched
performance of the new roll in tests conducted over a 72-hour period.

PST is suitable for almost any smooth, flat surface made of metal or plastic.
Metal surfaces may be coated with most paints, including Chemical Agent
Resistant Coating (CARC). It is, however, extremely important that you
follow proper surface preparation to enable optimal adhesion.
PST is not intended for attachment to wooden surfaces because of the
surface roughness of wood, and the wicking of rain or spray through wood
fiber. Screws are the preferred mounting method for wooden surfaces.
PST surface preparation is a simple, but critical process. The surface
cleaning procedure on page 19 demonstrates how to clean a shipping
container that has greasy residue and dirt on the intended mounting
surface as shown in Figure 2-4.
)LJXUH 'LUW\JUHDV\PRXQWORFDWLRQ
0RXQWLQJ6DYL7DJ67
6DYL7DJ67,QVWDOODWLRQ*XLGH
This demonstration was performed at about 50 degrees Fahrenheit on a
mounting surface covered with moisture and condensation. The optimum
mounting surface temperature for PST application is 60 degrees Fahrenheit
or above. At this temperature full adhesion strength will be achieved within
a few hours. But 3M has successfully applied PST to exposed surfaces
at temperatures as low as 40 degrees Fahrenheit. Even at these lower
temperatures, tags can be installed immediately after PST application;
full adhesion strength will be achieved within 24 hours.
Make sure you have the following cleaning materials available:
◆General purpose cleaner. Any commercial cleaner with a degreaser;
for example Formula 409® Cleaner, Ajax® All-Purpose Cleaner,
or Simple Green® All-Purpose Industrial Degreaser
◆Rags or paper towels
◆Scrub brush, bucket, and mild soap and water solution if needed
To clean the surface:
Determine where the
mounting sleeve or
SaviTag ST-654 is to be
attached to the shipping
container or asset. Be sure
that the surface to which the
tapes will be applied is flat.
Spray a liberal amount
of general purpose cleaner
onto the mounting surface.
&+$37(5
,QVWDOOLQJ6DYL7DJ67
Using rags or paper towels,
clean the mounting surface
so it is free of dirt, rust, and
loose paint flakes.
If the surface is heavily
soiled, use a mild soap and
water solution to scrub the
surface clean.
Ensure that the mounting
surface is free from
moisture and condensation.
