Why Prox PRD™?
Prox PRD™ is the only device that will pair with your phone in just a few seconds, operate without a mobile app (thus not relying on keeping an app open), and give you reliable phone separation alerts (no false alerts) before you leave your phone behind.
Built with patent pending ADVANCED ALERT TECHNOLOGY providing extremely reliable and adjustable distance smart alerts that doesn't require an app, safe alert zones, or safe alert times. The Prox PRD™ is the only phone separation alert device on the market that will let you know if you have left your phone behind even if the phone or Bluetooth® is temporarily off, such as during a phone update.

"Stopped me from forgetting my phone"
Sooner or later, I have to admit how many times I forget my phone. The PRD is just the right solution as it has stopped me from misplacing my phone. Very easy to use. The no tracking is a bonus. Great job Prox Devices!
"Adjustable alert tunes, wow, amazing"
As soon as we realized that you can change the alert tune by clicking the button 4 times, I changed mine. Now, my wife and I are not confused as to who is leaving their phone behind. Well done Prox Devices! Great feature.
"Fabulous product! Now I never leave my phone behind!"
I was a little skeptical at first, but I was up and going in less than 15 seconds. Very easy to use. Looking to buy more for my children so they don't lose their phones and I don't have to replace them. PRDs will be their Christmas gifts.
Should the PRD be turned off when disconnected?
It is not necessary to turn off the PRD while disconnected from the phone. Once turned off, the user might forget to turn it back on and may leave their phone behind. The PRD knows if it is disconnected from the phone for an extended period of time and will save power automatically.
How can the user tell if the PRD is working?
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.
What indicates that the battery needs to be replaced?
The first sign that the battery is starting to get low is when the loudness of the alerts become noticeably reduced and/or the LEDs become dimmer. At this point, it's recommended to replace the battery with a new one. Once the battery reaches a critical level, a low-battery chirp will go off every two (2) seconds until the PRD is turned off by pressing and holding the button for one (1) second. At which point, the PRD will not turn back on and the battery will need to be replaced. Click here for more information.
What should the user do if they are receiving too many alerts?
Too many alerts is caused by too low of a power setting. The easiest way to reduce the number of alerts is to increase the distance level (click the button three times.) Click here for more information.
Can you provide private labeling for corporate orders?
Yes, private labeling with your corporate logo is available for orders of 500 or more. There is a $10 surcharge for this service, and a 30% advance deposit is required for these orders.
Will the PRD alert in the middle of the night with an automatic phone OS update?
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.
Why would I want to adjust 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.
