Features
• ISO 18000-7 compliant active RFID data-rich tag
• 400-foot (122 meters) omnidirectional line-of-sight range for
monitoring, waking-up, and RF write/read operations
• Replaceable battery with a typical life of five years
• FCC, HERO, ETSI, RoHS (Directive 2002/95/EC) certified
Activating the Tag
The tag is shipped in sleep mode. You must remove and re-insert the
battery to wake up the tag. After you re-insert the battery, you can
initialize the tag.
1. Remove the battery cap.
Turn cap to open
Remove battery as shipped
2. Remove the battery. Wait a few seconds and then reinsert the battery,
matching the negative (–) and positive (+) terminals to the symbols
shown on the tag housing. The tag will not work if you install the
battery in the wrong direction (reversed).

Whenever a battery is inserted into a tag, the tag will emit 5 beeps.
Then, the tag will emit 2 short beeps to indicate adequate battery
voltage or 3 short beeps if a fresh battery is required.
Whenever a battery is inserted into a tag, the tag assumes that it is a
fresh battery. Inserting a used battery into a tag may result in what
appears to be a premature battery failure.
3. Replace the battery cap on the tag. Continue tightening the cap until
it is secure.

If the O-ring is not properly compressed by the cap, water leakage and
damage may occur.
Note: When the tag is not in use, disable the tag by removing, reversing,
and re-inserting the battery. Store the battery at room temperature
(50-80 °F or 10-27 °C ).
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.

Placing the Tag for Best Performance
9
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 a metal surface.
• Mounted at no less than a 6 foot (1.8m) elevation.
• Mounted vertically.
• Not mounted behind or between metal objects
The next figure shows an example of a tag mounted on an ISO container
according to the performance guidelines.
Figure 3: Asset tag mounted on an ISO container door
Note: Make sure you clean the surface of the container or other asset
before attaching the tag.
The tag will have 400-foot (122m) read/write range to Savi SR-650 Fixed
Readers. For the most consistent communications with the tag, the Fixed
Readers must be mounted:
• to have an unobstructed line-of-sight to the tag
![](/img.php?id=1076633&img=bga.png)
Savi ST-621 License Plate Tag Installation Guide
10
• at 20 feet (6m) or higher
caution: Tags mounted close to the ground may have less range.
Follow the instructions in the Savi Fixed Reader documentation to locate
and position the Savi Fixed Reader for best performance.
Mounting the Tag
You can choose among several mounting methods for the tag, including
using pressure sensitive tape (PST) 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.
There are two accessory mounting packages, which are sold separately:
• Savi Mounting Kit STA-1260-Black, which includes PST
• Savi Magnetic Mounting Kit STA-1261-Black
You can also use the following alternative fastening methods:
• Tie-wraps
•Twine
• Screws
caution: Use these and other alternative methods at your own risk.
If it is not possible or practical to use screws, use PST to attach the tag.
Use only 3M Corporation’s Automotive Acrylic Plus Attachment Tape®.
For ease of installation, the tag comes with this PST on the back of the
plastic mounting sleeve. PST mounting kits are also available for separate
purchase.

Pressure sensitive tape
Mounting the Tag
11
The magnetic mount clamps directly onto the metal surface. The magnets
hold the tag securely, but allow the tag and the magnetic bracket to be
removed quickly.
Once a mounting sleeve is fastened to an asset, you can leave it on the
asset even after the tag is removed so it is available for future use with
other compatible tags. 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.
Asset tags and mounting sleeves have a security hole through which a
nylon keeper band may be passed and tightened to secure the tag in place.

Replacing the Battery
The tag is equipped with non-volatile memory, which means stored data is
not lost when you replace the battery.
1. Remove the battery cap.
2. Remove the discharged battery from its compartment
For more information, see “Activating the Tag” on page 6.
Note: The lithium battery can be harmful to the environment. Follow
current procedures for safely disposing of lithium batteries. The battery
cannot be reused or recharged.
3. Install a 3.6V lithium "A" battery, matching the negative (–) and posi-
tive (+) terminals to the symbols shown on the tag housing. The tag
will not work if you install the battery in the wrong direction
(reversed).
4. Replace the battery cap on the tag.

Whenever a battery is inserted into a tag, the tag will emit 5 short
beeps, one second apart.
Then, the tag will emit 2 short beeps to indicate adequate battery
voltage or 3 beeps to indicate inadequate battery voltage. 3 short beeps
means the tag needs a fresh battery.
Whenever a battery is inserted into a tag, the tag assumes that it is a
fresh battery. Inserting a used battery into a tag may result in what
appears to be a premature battery failure.
After the beep, continue tightening the cap until it is secure.
