The FCC Wants You to know
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency
energy and, if not installed and used in accordance with the instructions, may cause harmful interference to
radio communications. However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
-Reorient or relocate the receiving antenna.
-Increase the separation between the equipment and receiver.
-Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
-Consult the dealer or an experienced radio/TV technician for help.
FCC Warning
Changes or modifications to this equipment not expressly approved by the party responsible for compliance (SCR
Engineers Ltd.) could void the user’s authority to operate the equipment

3. Installing the tag
It is important to correctly attach the tags to the cow's neck in a secure manner in order to avoid
them from turning or falling off.
To securely attach the tag to the cow’s neck:
1. Ensure that your tag assembly kit includes the following parts:
i. HR-Tag
ii. Belt, Weight & Buckle
2. Open the outside locker of buckle using the buckle opener (supplied with each system) or a
large flat screwdriver.
3. Mount the belt on the cow's neck in a way that the tag is positioned on the upper left side of the
cow’s neck. (when looking from behind).
4. Closely fasten the belt around the cow’s neck with a maximum of 1-2 fingers gap between the
belt & the neck.
5. Tighten the buckle's lever to lock the belt. Make sure that the buckle is completely closed and
secured (pushed in all the way)
A properly mounted tag should look like this picture:
