TR637: Bluetooth Jobsite Radio with AM/FM and USB MP3
FAQ
The bundle ships one RB48 Plus GMRS two way radio, one TR637 Bluetooth jobsite radio, the TR637 AC adapter (9V 2A), a charging dock and cable for the RB48 Plus, and user manuals for both devices. Everything is ready to use out of the box: charge both units, program or pair as needed, and head to the site.
As a 5W GMRS radio, the RB48 Plus typically reaches from about half a mile in obstructed areas up to a couple of miles in open terrain, with in-building coverage across large multi-floor facilities. Actual range depends on antenna height, terrain, and building construction, so plan for obstruction when you map your coverage.
The RB48 Plus operates on GMRS frequencies, which require an FCC GMRS license in the United States. No test is required, the license covers your immediate family, and application is done online. If you plan to program the radio to other frequencies, confirm the authorization for those frequencies with Retevis support first.
The RB48 Plus uses a 2000mAh lithium battery rated for up to 18 hours of use, which covers a full shift and then some. The included charging dock lets you park the radio overnight and start every shift with a full battery, and spare batteries are available separately for crews that run doubles.
Yes. The RB48 Plus carries an IP67 rating, meaning it is dust-tight and can be submerged in up to 1 meter of water for 30 minutes. It is also drop-tested to survive 2-meter falls onto hard surfaces, so rain, mud, and dropped radios are all part of a normal shift rather than a warranty claim.
Yes. The RB48 Plus has a 2.5mm single-pin accessory port that works with Retevis speaker microphones and VOX earpieces made for the RB48 series, including the EAS001 acoustic tube and EES004 G-shape earpieces. That makes it easy to go hands-free when crews are wearing gloves or hearing protection.
Switch the TR637 to Bluetooth mode and it enters pairing automatically. On your phone, search for TR637 in the Bluetooth settings and connect - pairing uses Bluetooth 5.0 and also supports hands-free calls, so incoming calls can be answered through the speaker without pausing the job for long.
Three ways: the included 9V 2A AC adapter charges it and powers it on a bench, a Type-C cable charges the built-in battery, and for remote sites it can also run on four C batteries (not included). The 5000mAh internal battery plays for 7-8 hours unplugged, which is plenty for a workday away from outlets.
The built-in 5000mAh lithium battery plays for 7-8 hours per charge over Bluetooth, AM/FM, or USB MP3. The rear USB port also outputs 5V 1A, so you can plug a phone in and top it up during the day - handy when the whole crew's phones die by mid-afternoon on remote sites.
Yes, and that is the point of the bundle. The RB48 Plus handles two-way radio traffic on GMRS frequencies while the TR637 plays music on Bluetooth, AM/FM, or MP3 independently - they are separate devices on separate systems, so a radio call never interrupts the site playlist, and vice versa.
The TR637 uses an external antenna and stores up to 30 presets per band, which pulls in stations reliably at most outdoor and semi-enclosed sites. Inside steel-framed buildings, reception varies with structure - a common workaround is to place the radio near a window or roll door for the strongest signal.
Both devices are covered by Retevis lifetime technical and customer support, lifetime free firmware and resource downloads where applicable, fast free shipping, and a 30-day money-back guarantee. If you need help programming the RB48 Plus or choosing accessories, Retevis support responds before and after the sale.
