What frequency does the RB648P use, and is it programmable?

The RB648P is a UHF radio that works from 400 to 470 MHz with 16 channels and 5W/1W switchable power. Channels, CTCSS/DCS tones, and other settings are programmed through PC software, so your fleet can match your existing radios or local business frequencies.

Do I need a license to use the RB648P?

In the US, the RB648P operates on licensed UHF business frequencies, so a license is required before transmission. If you need a license-free option in Europe, the sibling RB648 PMR446 version is the better fit - the comparison section above explains the difference.

Will the RB648P work with my existing RT668 radios?

Yes. As long as both radios are programmed to the same UHF frequency and CTCSS/DCS codes, the RB648P communicates with RT668 and other Retevis analog UHF radios. Security teams often run mixed fleets this way; our support team can help you match the settings.

Can the RB648P replace our Motorola CP200d radios?

The RB648P is an analog UHF radio, so it can talk with CP200d units programmed to the same frequency and code. Shelters, warehouses, and job sites have switched to RB648P fleets to cut costs while keeping their current channels.

How far does the RB648P reach?

Expect up to 3-5 KM in open terrain and reliable coverage through about 30 floors or a large building complex. Walls, steel frames, and terrain reduce range in real conditions, which is why relay channels and a gain antenna upgrade are available.

How long does the battery last, and how do I charge it?

The 2000mAh battery runs up to 18 hours per charge, enough for double shifts with battery save mode on. Each radio supports Type-C direct charging and a desktop charging dock, so radios can power up overnight or in the field.

What does IP67 protection mean for daily work?

IP67 means the radio is sealed against 0.1-micron dust and survives 1 m of water for 30 minutes, and the body passed 1,000 drops from 2 m. Rain, mud, and dusty demolition sites will not stop the radio.

Can I use earpieces with the HS001 speaker mic?

The RB648P uses a 2.5mm single-pin connector that accepts Retevis earpieces and speaker mics made for the RB648 series. The included HS001 clips to your collar or shoulder and puts the speaker and mic close to your ear and mouth.

How do the dual PTT and VOX help in cold or loud conditions?

The oversized front PTT and side PTT respond to gloved presses, so crews never remove gloves to talk in winter or around abrasives. VOX (0-9 sensitivity levels) transmits automatically when you speak, freeing both hands for tools or climbing.

What do the different bundle packs include?

Bundles run from single packs up to this 50-pack fleet set. The 50 Packs bundle pairs 50 radios with 50 HS001 speaker mics and 50 desktop chargers; other tiers add ten-way charging (RTC48T) or 10 earpieces - see the package details table above for the full breakdown.

Can all radios ship programmed to the same channel?

Yes. Tell our team your frequency and CTCSS/DCS code when ordering, and the radios can be pre-programmed to match so the fleet works out of the box. Later changes are simple with the PC programming cable.

Which chargers should larger fleets use?

Single units charge on the included desktop dock or via Type-C. For teams of six or more, the RTC48P six-unit charger speeds up morning prep, and the RTC48T ten-way charger covers ten radios at once - both are offered as bundle upgrades on this page.

Features

Long Range Walkie Talkie

The Retevis RB648 Plus features up to 5W transmit power. As a high-performance UHF heavy duty two way radio, it delivers long-range communication coverage of up to 350,000 sq.m, 30 floors, or 3-5 KM. Whether working across large sites, complex buildings, or remote operation areas, it keeps teams connected with clear and stable communication.

2000mAh Battery, Up to 18 Hours per Charge

A built-in 2000mAh lithium battery runs up to 18 hours, covering double shifts and overtime calls. Battery save mode trims consumption during quiet stretches. When the shift ends, Type-C and desktop charging bring radios back overnight.

Advanced Triple Proof: IP67 Protection Against Dust, Rain, and Drops

The RB648 Plus features an IP67-rated design that effectively keeps out 0.1-micron fine construction dust and withstands 1 m of water immersion for 30 minutes, ensuring reliable performance in harsh environments. After passing 1,000 drop tests from 2 meters, the radio maintains dependable durability. Built with a high-strength PC+TPE composite housing, it resists rebar scratches, scaffolding impacts, and tailgate drops, providing long-lasting communication reliability for construction, industrial, and outdoor operations.

Dual PTT Buttons Built for Gloved Hands

An oversized front button and a side PTT give workers two ways to key up. Winter gloves, work gloves, and vibration numbness cannot stop a large, positive click. Talk commands stay instant even on the noisiest deck.

HS001 Speaker Mic Kit Included (IP55)

Every radio in this 50-pack ships with the HS001 1-pin 2.5mm shoulder speaker mic. Clip it to a collar or vest strap and the large speaker keeps calls audible over saws and generators. The IP55 mic handles drizzle and dust while the radio stays holstered.

One-Key Group Call for the Whole Crew

A single press reaches every radio on the channel - no menus, no scrolling. Use it for shift starts, delivery arrivals, and evacuation orders. With 50 radios on site, one-second paging saves minutes every time.

Vibration Reminder for Loud Job Sites

When generators and saws drown out alert tones, the RB648P vibrates to flag incoming calls. Workers feel the alert through gloves and pockets. Important messages get answered even in the loudest corners of the site.

VOX Hands-Free Operation (0-9 Levels)

Adjustable 0-9 VOX sensitivity lets workers talk without touching the radio. Climbers, forklift operators, and two-handed trades keep working while they speak. Fine-tune the trigger point so site noise never keys the radio by accident.

Relay Channels

Retevis RB648 Plus has relay channels. The relay channels efficiently extend the call distance by connecting to the base station.

LCD Display

The RB648 Plus with screen helps users check the working status of two way radio. Its three backlight colors refer to different statuses. The red is transmitting, the blue is receiving, and the purple is on standby.

Battery Save

If you open RB648 Plus battery save mode, it can reduce battery power consumption, and conserve the battery power for a longer battery life.

Replaceable Antenna

Retevis RB648 Plus can be upgraded to a gain antenna, which enhances penetration and provides better signal reception.

2.5 Single-pin

Compatible with the earpiece and speaker microphone of RB648 two-way radios, it features a 2.5mm single-pin connector.

Rechargeable

The Retevis RB648 Plus radio has two charging methods,type-C charging and desktop charging. You can flexibly and conveniently choose the charging method to charge the walkie talkie for longer work time.

Anti-slip design

Retevis RB648 Plus two way radio uses an anti-slip design, which reduces the damage to the walkie talkie because of slipping during use. It increases the stability and durability of two way radio.

Emergency Alarm

The emergency alarm of the Retevis RB648 Plus helps ensure your safety. Retevis RB648 Plus has two alarm modes, remote and local Alarm. In emergencies, press the alarm key to turn on the alarm function to seek help.
