FAQ

Yes. RT48 operates on the US FRS (Family Radio Service), which the FCC allows without a license. There are no fees or paperwork - charge the radio, pick a channel, and talk.

IP67 means the RT48 is fully dust-tight and can be submerged in up to 1 meter of water for 30 minutes. Sprays, splashes, rain, and hose-down cleanings are all fine - just dry the charging contacts before docking.

The 1200mAh battery provides 7-8 hours of working time and 48 hours of standby. A full charge takes about 3-4 hours on the included USB charging base with the power adapter; charger output is 400mAh.

Yes. RT48 works with other FRS radios such as the RT22 and RT48H on the same channel and CTCSS/DCS code. Note that RT48 channels 1-16 are receive-and-talk channels; radios with more channels can still talk to RT48s on any shared channel.

Outdoors with clear line of sight, 2W FRS power reaches the band limit. Inside concrete or steel buildings, walls cut range significantly - customers typically cover a multi-story facility per channel, and signal bounces differently at every site. For large facilities, test one pack first or step up to a higher-power model.

Yes. Press the monitor button to hear activity on the channel. To listen discreetly, set the same frequency with a different CTCSS/DCS tone: you will hear the other party when you press monitor, but you will not transmit on their channel.

RT48 uses carrier scanning. When scan is on, the radio stops on any channel with an active carrier, so the team can follow activity across all 16 channels.

RT48 is programmed with the Retevis J9131P USB programming cable, which sets channels, CTCSS/DCS tones, and other settings from a PC. The SP/MIC/program jack is on the radio's top; see the accessories section for the audio adapter used with Kenwood 2-pin gear.

Yes. RT48 has an SP/MIC/program jack for audio accessories. Its native connector follows the Motorola GP328Plus style; to use Kenwood 2-pin earpieces, speaker mics, or programming cables, add the Retevis audio adapter (FC9084A), which Retevis lists for RT29/RT48/RT648.

RT48 comes in four bundles on this page: 1 pack, 5 packs, 6 packs with the C9059H six-way multi-unit charger, and 10 packs. Every radio includes its own USB charging base, battery, belt clip, and hand strap; the six-way charger refills six radios or six batteries at once.
