RETEVIS RT23 136-174Mhz + 400-480Mhz 128CHS Handheld Walkie Talkie, US Plug

Description

1. Not only can "monitor" two frequencies, but also receive two calls at the same time. In addition, you can set the volume mode through menu 35. MAIN means that the sound of the main frequency is louder when receiving, and SUB means that the sound of the sub-frequency is weaker when receiving. OFF means that both the main frequency and the sub frequency have the same sound
2. Turn on the cross-band repeater function (menu 6). You can choose one-way or two-way repeaters (menu 34). One type (single) means that the receiving and sending frequency of the repeater is specific. The radio will display 162R2375, 426T2375. It means that the transponder can only receive 162.2375 and send 426.2375. Two-way (double) means that the receiving and sending frequency of the transponder is random. The radio will display 162*2375, 426*2375. It shows that the transponder can not only receive 162.2375 and send 426.2375, but also can receive 426.2375 and send 162.2375.
The cross-band repeater function can also increase the communication distance. If you choose a two-way repeater, you can make UHF radio communicate with VHF radio. When the repeater function is turned on, you can also set whether to use broadcast PTT transmission (menu 33) and speakers (menu 32)
3. You can set Sub-PTT via the sub button. If this is the case, there is no need to select a transmission channel. Press PTT to transmit the main channel, press the other side button to transmit the sub-channel. very convenient
4. The channel knob can be rotated 360 degrees. You can use this knob to operate the menu up and down
