Replacing the Main Battery
Savi SensorTag ST-674 Installation Guide 13
The tag beeps twice if you install a fully charged battery. The tag beeps
three times if you install a battery with low charge; replace it with a
charged battery. When removing and replacing a charged battery, you
may need to wait a few seconds after replacing the battery to hear the
confirmation beep.
4. Replace the battery cover.
Turn the battery cover
counterclockwise 1/4 to 1/2 of
a turn to properly seat the
cover. Turn the battery cover
clockwise until it fits flush
with the tag case. Be careful
not to overtighten.
Make sure the battery cover is
completely closed and that it
is not cross-threaded.
5. Dispose of the used battery according to local safety requirements.
CHAPTER 2
Installing the Tag
14 Savi SensorTag ST-674 Installation Guide
Tag Placement
Savi Technology recommends that you mount Savi SensorTag ST-674 by
adhering the tag and supplied plastic mounting sleeve with pressure
sensitive tape (PST) to the inside or outside of a Class VIII container or
plastic, cardboard, or wood container or box. You can also loosely place the
tag inside a non-metallic container or box.
PST Reliability and Durability
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 mounting sleeve. PST mounting kits are also available for
separate purchase.
Once a mounting sleeve is fastened to an asset, you can leave it on the asset
even after Savi SensorTag ST-674 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. 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 -40ºC to +158ºF (–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)
Savi’s tests confirm the adhesion integrity and reliability of 3M PST.

Savi SensorTag ST-674 Installation Guide 15
◆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.
◆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.
Achieving Maximum Communication
Savi SensorTag ST-674 achieves a 300-foot (91.44 meters) read range from
SR-410 and SR-650 fixed readers. To achieve the most consistent
communications with the tag, the fixed readers must be mounted:
◆To have an unobstructed line of sight to the tag
◆At 20 feet (6 meters) or higher
◆With the reader dome pointed downward
The following photos show specific Savi SensorTag ST-674 mounting
locations on Class VIII containers. Typical locations include mounting the
tag inside the middle of the container or on the outside of the container on a
flat surface.

Mounting Savi SensorTag ST-674
The mounting method for Savi SensorTag ST-674 includes using pressure
sensitive tape, nylon tie-wrap, and a plastic mounting sleeve. This method
prevents accidental loss of the tag by sudden impact, vibration, or shock
during transport.
Savi SensorTag ST-674 includes these mounting fasteners:
◆PST
◆Nylon tie-wrap
◆Plastic mounting sleeve
Mounting Savi SensorTag ST-674
Savi SensorTag ST-674 Installation Guide 17
1. Clean the location on the container where the mounting sleeve is to be
attached.
2. Obtain a mounting sleeve
with PST installed and
carefully remove the red
protective film covering.
Avoid touching the PST
adhesive.
3. Position the sleeve horizontally or vertically, making sure there is at
least 4 inches (10 cm) of clearance at the opening of the sleeve to allow
the Savi SensorTag ST-674 to be inserted. Be sure that the surface to
which you will apply the tape is flat, and that the sleeve can move
freely to compress the tape in the next step.
4. When the sleeve is level,
press it into place. Apply
pressure to the tape strips
by pushing firmly against
the inside surface of the
sleeve. To assure a good
bond, apply as much finger
pressure as possible and
work fingers on the area
over the tape strips.

Installing the Tag

5. Insert the tag into the sleeve
and insert a wire loop or
nylon tie-wrap through the
two retaining ears. No tape
curing time is required prior
to installing the tag.
The mounting sleeve is
equipped with a tie-wrap
groove to ensure that Savi
SensorTag ST-674 is
securely fastened.
6. To prevent the tag from
dislodging from the tag
mounting sleeve as a result
of sudden impact or
extreme shocks, insert the
supplied tie-wrap through
the sleeve.
