For more information, see the Savi SmartChain Mobile User Guide .
Placing the Tag for Best Performance
Savi Technology recommends that you mount the tag on a flat surface, with the tag aligned vertically. For best
performance, place the tag as high as possible, safe from impact (for example, between the ribs of an ISO-type shipping
container), and away from obstructions on the asset.
Mount the tag 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.

Typical locations include mounting the tag inside the middle of the container or on the outside of the container on a flat
surface.
For best performance, make sure the tag is:
•Mounted on metal surface
•Mounted at no less than a 6 foot (1.8m) elevation
•Mounted vertically
•Mounted horizontally
•Not mounted behind or between metal objects
The figure shows a tag mounted on an ISO container according to the performance guidelines.
Note: Make sure you clean the surface of the container or other asset before attaching the tag.
The tag has 300-foot (100m) read/write range to Savi SR-650 Fixed Readers. For the most consistent communications
with the tag, the readers must be mounted:
•to have an unobstructed line-of-sight to the tag
•at 20 feet (6m) or higher
Caution: Tags mounted close to the ground may have less range.
Follow the instructions in the Savi SR-650 Fixed Reader Installation Guide to locate and position the Savi Fixed Reader
for best performance.
Placing the Tag on Aircraft Pallets
Place the tag at least 6 inches (15.24 cm) above ground level, on the long side of the pallet (for example, the 108-inch
side of a 108 x 88 inch 463L pallet) to avoid forklift damage. Mount the tag in the middle of the rail of the pallet, directly
above one of the tabs (or dog ears) that protrude from the rail.

Caution: Do not place tags on the side of the pallet that locks into the aircraft. Place it on the side that faces away
from the forklift.
Mounting the Tag
Before you install the tag, make sure the following materials, which are included with the tag, are available:
•Pressure sensitive tape (PST)
•Two tie wraps
Whichever mounting method you select, the goal is to prevent accidental loss of the tag by sudden impact or vibration
during transport. The best mounting method for your application depends on the material you attach the tag to and your
personal preference.
Mounting with Tape
1. Open the tag mounting kit and remove the roll of PST.
2. Unroll the tape completely. The PST has two sides of adhesive. Immediately apply the entire length of PST to the
back of the tag
3. Peel the backing from the PST to expose the adhesive.
4. Position the tag on the asset and press firmly until the tag sticks to the asset.
Mounting with Tie Wraps
The ST-616 tag has mounting holes at each end of the tag, as shown in the figure below:
Mounting hole for tie wrap
To mount the ST-616 tag using tie wraps, thread a tie wrap through each mounting hole and affix the tag to the asset.

Mounting with Rivets
1. Determine where the tag is to be attached to the asset.
2. Mark the location of the tag rivet holes on the shipping container or asset.
3. On the asset, drill holes at the locations you marked in step 2.
4. Return to the location where the tag is to be attached to the asset. Align the rivet holes on the tag with the rivet holes
you made in step 3.
5. Push the head of the rivets through the tag.
6. Use a handheld rivet gun to clip the nail of the rivet and secure the tag to the asset. Avoid fastening the rivets too
tightly to prevent damage to the tag.
Mounting on a Vehicle
The ST-616 tag can be mounted on a vehicle. The preferred mounting location is on the license plate in the back of the
vehicle, as shown in the following figure:
When mounting the tag on a vehicle, ensure the following:
OpenTopic | Savi ST-616 Asset Tag Description | 9
XML to PDF by RenderX XEP XSL-FO Formatter, visit us at http://www.renderx.com/
•the tag is mounted with its back to the vehicle (tape on the bottom)
•the tag is mounted horizontally
If the tag cannot be mounted horizontally, the tag can be mounted vertically, as shown in the following figures:
or

If mounting multiple tags, ensure that:
•tags must not be mounted one on top of the other
•tags must not be touching
•tags must be no further than 1 foot apart
•there is a minimum clearance between tags of 1 inch
Conserving the Battery
The ST-616 is equipped with a non-replaceable battery that can register up to 60,000 tag events before the battery life
is depleted. Overpolling may cause the battery to be depleted prematurely. The tag has several mechanisms that protect
against overpolling.
Minimizing a tag’s exposure to unintentional reader signals can help extend battery life. The following sections provide
suggestions to conserve a tag’s battery life.
Avoid Overpolling
The most common cause of early battery depletion is overpolling. Overpolling, which can occur when the tag is left idle
within range of an RF reader, such as in a warehouse, shipping yard, or near a gate where fast UHF polling is used. To
avoid overpolling, the ST-616 uses an overpolling suppression feature, which extends battery life in difficult RF
environments such as long-term storage facilities.
Employ Good Business Practices
•Use the Savi tag hibernation mode for tags stored long-term or for future use.
•Maximize use of LF signposts and mobile device operations so the UHF receiver can be left off during normal
operation of the tag. You can turn on the UHF receiver using a LF signpost or LF mobile device prior to issuing
other commands or collections over the UHF link.
Protect Stored Tags
You can protect unused tags from unintentional polling by storing them in a fully enclosed metal container, placed away
from areas where fixed readers or mobile devices are regularly used. You can also wrap tags in aluminum foil to shield
them from nearby UHF signals. To be effective, you must apply multiple, overlapping layers with foil-to-foil contact.
Isolate Storage Areas
Prevent or minimize the polling of stored tags by isolating the storage area. Storage areas should be more than 600 feet
(183m) away from readers mounted within 10 feet (3m) of ground level and 900 feet (274m) away from readers mounted
15 to 20 feet (4.6 to 6m) above ground level.
Note: Storage areas can also be shielded from reader activity by buildings. Be sure that stored tags are not receiving
signals over the top of low buildings, from elsewhere in a storage area, or from within a nearby building.
Low Battery Warning
When the ST-616 detects that its battery power is low, the tag sends a low-battery message to the Savi software in
response to a collect request. At that time, the ST-616 battery is depleted and the tag must be replaced.
