Frequently Asked Questions
Alert distances can vary depending on your surrounding environment (indoor, outdoor, high ceilings, etc.), the RF environment where the PRD is worn on the body, the mobile OS version, and orientation/location of the phone.
The default alert distance has been extensively tested to alert you before you forget your phone and leave it behind in environments such as at home, at the office, in the car, or in a restaurant, store, hotel, etc. Different environments may have different alert ranges for the same alert distance setting. The PRD will alert before you get too far from your phone. Alert distance ranges can vary greatly and may be shorter or further for some phone models and environments, especially if both the PRD and phone are outside and there are no obstructions.
There are five (5) alert distance settings. The default is setting 3, which will typically alert between
50 feet and 150 feet. In the same environment, the lower settings (settings 1 & 2) will give you shorter alert distances, while the higher settings (settings 4 & 5) will give you longer alert distances.
Setting 1 (one beep) represents the shortest distance and the reconnect alert will only occur when in immediate proximity of the phone or once the phone is picked up. Setting 1 has the highest sensitivity and may not be the best selection based on the circumstances and the surrounding environment.
Setting 5 (five beeps) represents the furthest distance, which allows for freedom to roam around with fewer unneeded alerts. Setting 5 can alert at distances further than 150 feet in outdoor settings with little to no obstructions, but alert distances can still vary greatly.
The PRD does not alert at very short distances such as 10 feet.

In order to get a shorter alert distance, you will need to put the PRD in "Adjusting Alert Distance" mode by quickly pressing the button three (3) times. The following beep(s) that you hear indicate the PRD's current alert distance setting. The default is setting 3, which is represented by three (3) beeps. Once in this mode, a single press will increment the distance setting, with setting 1 coming after setting 5 in rotation.
To exit this mode, once you get to the selection that you want, stop pressing the button, wait a few seconds, and the PRD will automatically lock in that setting (indicated by a confirmation tune) and exit out of the "Adjusting Alert Distance" mode and return to normal operation.
The lower settings (settings 1 & 2) will give you shorter alert distances, with setting 1 giving the shortest alert distance and it being the most sensitive. It is designed this way so that a reconnection will only occur when the phone is picked up and the PRD is next to it.
The PRD does not alert at very short distances such as 10 feet.

The PRD only works after it is paired with a phone. If paired, you may not have gone far enough away from your phone for the PRD separation alert to activate. The default distance (setting 3) in some RF (Radio Frequency) environments may exceed 70 feet. This distance can be adjusted. Click here for more information.
To determine if the PRD is turned on and connected to your phone, simply click the button one (1) time. Here is a quick reference guide:
a) No LED — PRD is off
b) Blue LED — PRD is on and connected to the phone
c) Red LED — PRD is on but not within proximity of the phone
d) Blinking Blue LED — PRD is ready to pair with a phone. (It is only during this pairing / bonding period that the blue LED will be blinking on the PRD.)
There are multiple alert tunes that encompass a variety of alert durations, pitches, and frequencies, thus allowing those who hear better at certain frequencies to find a suitable audible sound. Some alert tunes may be more practical in loud environments. Unfortunately, there is no way to make the tune any louder or longer. Since the PRD operates on a replaceable CR2032 coin battery, there is limited power.
The PRD is designed to initially only alert once, to conserve battery life. However, there are louder and longer alert tune options to choose from and you can change the alert tune by quickly pressing the button four (4) times and then toggling through the alert tune options with each single-click. Once you get to the selection that you want, stop pressing the button, wait a few seconds, and the PRD will automatically lock in that setting (indicated by a confirmation tune) and exit out of the "Selecting Alert tune" mode and return to normal operation.
Note: If the PRD remains still for 15 minutes and is disconnected from the phone, it will give a secondary alert upon movement.

The phone's Bluetooth must remained turned on for the PRD to function properly. If the phone's Bluetooth is intentionally turned off and the phone is in proximity of the PRD (e.g., when switching your phone to Airplane mode on an airplane), the PRD will alert only once, when it's moved, to let you know that it cannot connect to your phone. If the phone's Bluetooth is turned off while not in proximity of the PRD, as a safety measure, the PRD may continue to alert each time it is initially moved after being still for at least 15 minutes.
Too many alerts is caused by too short of an alert distance. The easiest way to reduce the number of alerts is to increase the distance level. Click here for more information on how to change the alert distance.
Alert distances can vary depending on the surroundings and RF environment. Moving indoors or outdoors, or simply wanting a shorter or longer alert distance can be helpful under different scenarios. For example, at the airport, you may want a very short alert distance. Click here for more information.
If you are experiencing more alerts than desired, simply increase the alert distance by pressing the button three (3) times, wait for the beeps to indicate the current setting, then single-click to increment. Keep in mind, with default "Home" mode, if you set the PRD down, it will not alert while you walk around with your phone. Click here for more information.
One click of the button will flash either a blue or red LED if the PRD is turned on. A blue LED indicates the PRD is currently connected to the phone. A red LED indicates the PRD is currently not connected to the phone. Click here for more information.
Directional and range information is only needed if you've already lost your phone, but the PRD helps prevent you from misplacing or losing your phone in the first place, so there would be no need to find or locate your phone. Additionally, directional and range info would require the use of an app and tracking, both of which are not required for the PRD to operate.
The PRD is designed to be paired to one (1) phone to avoid confusion — unmeaningful alerts caused by two phones and their different proximities. However, there are rare situations when it might be beneficial to pair to two (2) phones simultaneously, but it is recommended that the shortest alert distance is used so the PRD is only alerting based on the phone closest to the PRD.
Alternatively, multiple PRDs can be paired to the same. This may be preferred if you have multiple personal items (e.g., keys, purses, etc.) that you rotate regularly and use one at a time and don't want to detach and reattach the PRD. The PRD that is in use that day will automatically activate when on the move and the remaining PRDs (not in use) will go into sleep mode to conserve battery until they are moved with their attached personal item. Click here for more information.
No, the PRD is designed to be kept on continuously 24/7. The device has proprietary software which allows for battery savings when not in use. And, the device will not alert at night if it is not moving, thus it won't alert during a phone software update.
An app is not required in order to use the PRD. Without the use of an app, your location info and whereabouts are not known. Prox Devices (and the Prox PRD®) does not collect (nor do we sell) any personal user data. This enables Prox Devices to always give our users the peace of mind of true 100% privacy.
When the battery reaches a critically low level, you will hear a low battery alert chirp every two (2) seconds. This will only happen when the PRD is moved, which means no middle of the night low battery alerts.
To stop the chirping, you will need to turn the PRD off by pressing and holding the button until you hear it power off. Once turned off, the PRD cannot be turned back on until the battery is replaced. Please note that when the battery is replaced, the PRD's default settings will be restored.

The PRD is not a location tracker and its patent pending Advanced Alert Technology offers:
1) The most reliable phone separation alerts;
2) Smart learning of your environments;
3) Movement-based alerts that knows when you are leaving your phone behind and when you are not;
4) No app and no tracking (100% privacy);
5) No false alerts, only reliable anti-loss separation alerts;
6) Adjustable alert distances to your specific preference based on your surrounding environment;
7) Adjustable alert tunes to your liking; and
8) Automatic battery conservation so that your PRD can last longer before battery replacement.
Other trackers help you find lost items; they are dependent on a phone to do so, but their effectiveness drops when the phone is lost. The PRD helps prevent phones (and all of the valuable information on them) from being lost. With that said, the PRD can actually work well with other location trackers.

There are two basic operating modes: HOME mode (default) where the PRD alerts only when it is moving away from the phone, and TRAVEL mode, which does the same as Home mode plus it will also alert you when the phone is moving away from the PRD. Travel mode works well in busy environments (e.g., airport, restaurant, etc.) and someone accidentally (or intentionally) picks up your phone and walks away.
To adjust this mode, press the button five (5) times, then hold the button down until you hear 1 beep (HOME) or 2 beeps (TRAVEL) indicating the current setting, then single-click to toggle. Click here for more information.
The defaults are: Level 3 distance setting, standard alert tune, and "Home" mode. These default settings are reset when the battery is replaced.
No, the PRD is programmed to know if the phone is going through an OS update and will not alert upon disconnect or reconnect. This is also true if you manually turn off / on Bluetooth in Settings.
If you are not in camera or video mode, double-clicking the button will simply increase the volume on the phone, whether you are watching a video from your phone or a streaming platform (e.g., YouTube, Vimeo, Facebook, Instagram, TikTok, etc.), or scrolling through your photo albums. Click here for more information.
If the button is pressed more than five (5) times, you will have toggled past all of the device's feature options, at which point nothing will happen and the PRD will just resume operating normally. If you continuously press the button, it won't have any effect on your PRD's current settings.
