The Gimbal Series 21 Proximity Beacon (the 'Beacon') is a small, battery-powered device that transmits a Bluetooth™ Smart / low-energy (BLE) signal that can be detected by other devices (e.g., smartphones or other devices capable of receiving the signal). This signal enables identifying the Beacon as well as other telemetry information to the receiving device (e.g., battery level and
The Beacon works by periodically waking up, transmitting this signal via short-range radio (Bluetooth Smart/LE) and then returning to a low-power state. The Beacon has no user interface (UI), cellular or GPS capabilities. The Beacon's identity is encoded within the signal it transmits and includes a sub-segment device type.

The Beacon is not FDA certified. Any use by customer in an environment requiring such certification is at customer’s risk and Customer is responsible for any liability resulting from such use.
Each Series 21 Beacon comes with double-sided adhesive tape that can be used for mounting purposes. Other mounting accessories are not included. It's advisable to leave your Beacon in its box and powered off until ready to use. When ready to use, remove your Beacon from its unit box and its protective bubble wrap sleeve.
Your Beacon is now associated with your Gimbal Developer Account and ready for use. Repeat step 4 to activate additional Beacons on your account.
Note: If you've ordered Series 21 Beacons in bulk, we can provide you with a shipping manifest that allows for bulk activation of your Beacons in Gimbal Manager. Contact Gimbal Support through Gimbal Manager on the web for further details.
After removing your Beacon from its unit box and sleeve, open the Beacon by pressing the two latches on opposite sides of the Beacon simultaneously with one hand while holding the front part of the Beacon with the other hand. Once you've opened your Beacon, flip the small power switch located between the two sets of batteries from the 'Off' position to the 'On' position.
Once you’ve powered on your Beacon, you’ll notice a green light flashing on the exterior of the Beacon for approximately 10 seconds. This lets you know that the Beacon is functioning normally. Once the Beacon finishes its startup cycle, the light will turn solid to indicate battery status for 3 seconds (green indicates good; red indicates that batteries need to be replaced) before the light turns off and the Beacon enters its normal transmission state.
Close the Beacon by latching the front and back housing together until it clicks and your Beacon is ready to use.
Note: An optional physical security screw is provided which when installed, makes it difficult to open the Beacon. It can be found mounted on the inside of the Beacon’s bottom housing in a smaller holder. To use, carefully remove the screw from its holder, close the Beacon, and insert the screw in the holder found in one of the Beacon’s closure tabs using a 1/16" hex screwdriver until snug.
To check whether your Series 21 Beacon is operating normally, simply press the button on the front of the Beacon.
To see your Beacon from a mobile application, download the Gimbal Beacon Manager application from the App StoreSM on an iOS® device and login using the same Gimbal Developer Account (and organization, if configured) which you have used to activate your Beacon. Once logged in, you will see all of your Beacons that are powered on and near your device under the My Beacons tab.
Gimbal Series 21 Beacons are designed to never need configuration when used in conjunction with the Gimbal SDK as integrated into your mobile application. In fact, more than 95% of our Beacons that have been deployed as of this writing have never been reconfigured. However, should you want to adjust certain settings, you may do so.
Note: presently, an iPhone® 4S or newer is required for this step. Formal support for iPad® and other operating systems may be available in the future.
Note: At this point, you have assigned a configuration to your Beacon in Gimbal Manager on the web but you still need to apply the configuration to your Beacon.
Once your Beacon shows a different ‘Assigned Configuration’ vs. its ‘Applied Configuration’ in Gimbal Manager on the web, you’re ready to apply the configuration to your Beacon.
Note: If you wish to reconfigure a Beacon that is powered on, you may do so by simply holding the exterior button for 3 seconds until you see the light start to flash slowly.
The Beacon is easy to install and comes with adouble-sided adhesive tape that is designed to adhere to most clean, even surfaces. To install:
Figure 1: Bottom housing with the double-sided tape applied
Figure 2: Installed bottom housing
Figure 3: Top housing installed
CAUTION: When the Beacon is closed, the top and bottom housings are NOT flush. An example of a properly closed Beacon is shown in Figure 4 below. This is designed so that in the case of an uneven surface, the Beacon can still be opened properly to replace batteries when it becomes necessary
Figure 4: Properly closed Beacon is NOT flush
DO NOT apply excessive pressure while closing the Beacon or after it has been installed as doing so can damage the Beacon
The Beacon has four (4) AA alkaline batteries that will typically power the Beacon for approximately 18 months but depends on configuration and environment. To test the batteries, make sure the Beacon is powered on and press the external button. If it lights ‘Green’, the batteries are good. If it lights ‘Red’, the batteries need to be replaced. Alternately, you can see the latest battery status for you Beacon within you Gimbal Manager account.
To replace the batteries:
Note: It’s important when replacing the batteries to only use new, matched batteries of the same type. Using mixed batteries may cause problems with the Beacon.

Scientific research on wireless devices and radio frequency ("RF") energy has been conducted worldwide for many years, and continues. In the United States, the Food and Drug Administration (FDA) and the Federal Communications Commission (FCC) set policies and procedures for wireless devices. The FDA issued a website publication on health issues related to usage of cell phones where it states, "The scientific community at large believes that the weight of the scientific evidence does not show an association between exposure to RF from cell phones and adverse health outcomes." Still, the scientific community does recommend conducting additional research to address gaps in knowledge. That research is being conducted around the world, and the FDA continues to monitor developments in this field. You can access the FDA website at http://www.fda.gov (under "C" in the subject index, select Cell Phones > Research). You can also contact the FDA toll free at (888) 463-6332 or (888) INFO-FDA. The FCC issued its own website publication stating that "there is no scientific evidence that proves that wireless telephone usage can lead to cancer or other problems, including headaches, dizziness, or memory loss." The publication is available at https://www.fcc.gov/engineering-technology/electromagnetic-compatibility-division/radio-frequency-safety/faq/rf-safety or through the FCC at (888) 225 5322 or (888) CALL-FCC. The National Cancer Institute (NCI) states that concerns about the potential health effects of using cellular phones - "and specifically the suggestion that using a cell phone may increase a person's risk of developing brain cancer - are not supported by a growing body of research on the subject." You can access NCI's review of the research via this cancer.gov article.
If you are concerned about RF, there are several simple steps you can take to minimize your RF exposure. You can minimize usage of the device near the body. You can also place more distance between your body and the source of the RF, as the exposure level drops off dramatically with distance. Wireless devices marketed in the United States are required to meet safety requirements regardless of whether they are used against the head or against the body.
