FAQ：
What is the transmission distance of RB48P?
The Retevis RB48P long range walkie talkie has a maximum transmission power of 5W, making it a long-range GMRS heavy duty two way radio. It offers a call distance of 350000sq.m, 30 floors, or 3-5KM.
How to make RB48 FRS radio talk with RB48P GMRS radio ?
RB48 can't talk with RB48P directly because they have different CTCSS/DCS settings.
You can turn off CTCSS/DCS,RB48 can talk with RB48P directly.
In the standby state of direct call mode,press the [MENU] key twice,adjust the CTCSS/DCS number to "00".
Do i need to apply the a license if use RB48P?
In the United States, the use of GMRS radios requires a license issued by the Federal Communications Commission (FCC). Therefore, the use of the RB48P requires a GMRS license. This license is usually valid for 10 years and does not require an exam.
Do i need to programming before use?
The RB48P GMRS walkie-talkie is designed for ease of use, allowing users to start communicating right out of the box. Simply power on the device, select the appropriate channel, and begin using it immediately.
Can RB48P use a repeater to extend the communication range?
Yes.The RB48P heavy-duty two-way radio is equipped with relay channels, allowing it to connect to a repeater and significantly extend communication range. We recommend pairing the RB48P construction walkie talkie with the Retevis RT97L repeater, which is a compact and portable 25W GMRS repeater.
