Care & Maintenance

Protect your Silent Beacon and accessories as you would any other type of sensitive electronic equipment. If your Beacon requires cleaning, consider the following:

The Beacon can be cleaned with a dry cloth if needed. The cords can be dry dusted as required. Avoid getting moisture or liquids into any buttons, parts, or other open areas, including the Micro-USB port and speaker/microphone holes.

Main Alert Button

The larger button with a raised center is the main alert button. This button will place the emergency phone call as well as send your custom alert messages to your other emergency contacts via text message, push notification, and email.

Emergency Alert Mode

Pressing the Main Alert Button for around 2 seconds (the LED will turn red and the Beacon will vibrate) will send the Emergency Alert by placing a phone call and sending your GPS location to your Emergency Contacts.

Silent Mode

While in the Emergency Alert Mode you can press the secondary button for 1 second to activate Silent Mode. This will disable the sounds and lights to discreetly send for help without anyone knowing.

To deactivate Silent Mode, hold the secondary button down again for 1 second and the LED and speaker will turn back on. This process can be repeated as needed.

Important: Inside the main menu of the App you will see an activate/deactivate emergency alert.  This must be pressed to turn off the Emergency Alert Mode. For safety reasons you cannot turn off an Alert by the Beacon itself.

Important:   To place an Emergency Alert directly from the App, hold the Activate Emergency Alert Button in the main menu for 3 seconds (you will see a countdown timer) to place an Emergency Alert manually.

App Setup Guide 

App User Guide

Adding a Phone Call Contact

Within the Silent Beacon Application, you may add emergency contacts that you wish to alert, including 911 or emergency personnel by going to the “Contacts” page. On the top right of this page, you will see an “Add Contact” icon. Pressing this allows you to manually enter (as in adding 911 or specific people not stored in your contacts) or automatically import from your smartphone’s address book.

After you have added a contact, you will be able to choose how you want your contact to be reached. There will be a toggle that allows you to turn on and off specific alert modes. These modes can be adjusted per contact. Toggle Call on/off to place a call when the Silent Beacon is activated.  Only one contact can be called in Alert Mode.

Placing a Phone Call

Make sure you have the selected the Call toggle for a primary contact within the Emergency Contacts settings of the App. Once you have gone into Emergency Alert Mode you will be able to send and receive phone calls through the Silent Beacon.

Note: When you are in Silent Alert Mode, no lights or audio will be heard through the speaker; however, all alerts will still be sent to your Emergency Contacts, and once your Primary Contact picks up, they will be able to hear you. To hang up, simply go to your smartphone and manually “End Call.” This setting will not work for tablets or other products that do not connect to a phone line.

Check Pairing Status

You may check the status of your Silent Beacon’s pairing at any time by viewing the large Beacon image inside of the App. It will be gray if your device is not paired, Black if paired.

You may also tap either button on the Silent Beacon to see the pairing status, Blue LED means the Beacon is connected to the App, Red means it is not.

Powering On/Off

Pressing both Buttons for 5 seconds will initially turn on the Silent Beacon. You will see the LED light up and change color, hear an audio sequence, as well as feeling the Beacon vibrate, letting you know this was successful. When you are not in an emergency, you can turn off your Beacon by holding both buttons for 5 seconds.

Find Your Beacon

Within the Beacon section of the App, there is a feature called “Find your Beacon” that will illuminate when the Silent Beacon is connected. If you lose your Silent Beacon you may select the “Find” icon when within Bluetooth range to help you find it. The Silent Beacon will also blink blue and vibrate to help you locate it.  The range finder icon lets you know if you are getting closer or further from the Beacon.

Battery Status

You can check the status of your battery of your Silent Beacon within the Beacon section of the App.  If your battery gets to 5%, it will vibrate, and orange LEDs will flash to let you know it needs to be recharged. When connected to a power source, the LEDs will glow green to let you know it is charging. Once the battery is fully charged the light will stay lit until removed from the USB Cable.

Factory Resetting Your Beacon

To reset the Silent Beacon, hold both buttons down for 30 seconds. The LEDs will cycle colors, the restart chime will begin and the Beacon will vibrate to let you know the reset has been completed.

Firmware Updates

Firmware is software that runs inside many types of electronic devices, including your Silent Beacon. The Silent Beacon allows over-the-air firmware updates. Firmware updates may be released to improve important security encryption, performance and better functionality. Visit directly to learn more about available updates or consult the Firmware Update portion of the App for more information.

Wearing Your Beacon

The Silent Beacon is intended for use either on the wristband, multipurpose clip, keychain or as a pendant.  We have included a universal 18m wristband, multipurpose clip, and the Silent Beacon was created to seamlessly integrate with a keyring.

IMPORTANT! Regardless of how you choose to wear the device, make sure the speaker/microphone side of the Silent Beacon is positioned as close to your mouth as possible. This will maximize the microphone clarity, allowing your voice to come through loud and clear.

Device Bluetooth Connectivity

The longest range (under perfect conditions) when sending an Alert from the Silent Beacon to your smartphone is approximately 800 feet.


Note: In reality, you will probably find the range to be somewhat shorter due to physical obstructions and electromagnetic interference.

The sound from the Silent Beacon will slowly deteriorate as you move it further away from your compatible smartphone, tablet or Bluetooth device. To restore sound quality, move back into range. All sound and functionality will stop if you move completely out of range. After moving out of range, your Silent Beacon will try to reconnect to the lost smartphone periodically. The App will alert you, indicating that it can no longer find the Silent Beacon. It is strongly advised that you test your Device’s range, connectivity, and audio levels before you need the Silent Beacon in an emergency.  When you are within range, you can use the “Find your Beacon” feature within the main menu to help locate your Silent Beacon if lost.

 Additional Warnings & Safety Information

Permanent hearing loss may result from long-term exposure to sound at high volumes. Use as low a volume as possible. Speakers are capable of delivering loud and high-pitched sounds at high volumes. Under certain circumstances, exposure to such sounds can result in permanent hearing loss damage. The volume level may vary, based on conditions such as the smartphone, tablet or you are using and volume settings. Avoid prolonged use of the speaker at excessive sound levels.

Reduce the risk of hearing damage by following these safety guidelines during use of the Silent Beacon Device:Turn the volume control to its lowest level when connecting the speaker, and then slowly adjust the volume control to a comfortable level. Keep the volume at the lowest level possible. If increased volume is necessary, adjust the volume control slowly. If you experience discomfort or ringing in your ears, immediately discontinue using the speaker.

With continued use at a high volume, your ears may become accustomed to the sound level, which may result in permanent damage to your hearing without any noticeable discomfort. Use of a speaker will impair your ability to hear other sounds. Use caution while using your speaker when you are engaging in any activity that requires your full attention.

IMPORTANT: Always drive safely, avoid distractions, and follow local laws!

Use of the speaker while operating a motor vehicle may be regulated by local laws. Check with your local authorities. Use caution while using your speaker when you are engaging in any activity that requires your full attention.
