Retevis RB669 is a radio, usually used in scenarios that require simple and reliable communication. It also has Freenet frequency and is loved by German customers. I have summarized the problems encountered by customers. If you encounter similar problems during use, you can refer to this article.
1. Computer punctuation setting problems
Some customers often ask about some problems in the software: such as being unable to change CTCSS, displaying garbled characters when opening the software, etc. This may be caused by the computer punctuation settings. Next, I will tell you how to solve this problem by modifying computer punctuation.
Here is how to set it: open the computer’s control panel, select “Region”, then “Other Parameters”, and then change the decimal point symbol. Then you can use the software normally to modify settings.
2.The operation method of frequency pairing is as follows:
Step 1: Download the RB669 software and turn on “Code Switch” in the software
Step 2. When the radio is turned off, press and hold PTT and side button 1, and turn on the power knob at the same time. After the RB669 beeps and the green light flashes, the radio enters the receiving state.
Step 3. The transmitter sends a signal, and the radio receives and saves the settings so that they can talk to each other.
Step 4. When pairing the frequency, make sure that the channels of the two radios are consistent. After the end, turn off and restart the radio, and all the paired frequency information is stored, then the pairing is complete.
The above are the problems that customers often encounter during use. I hope my reply will be helpful to you.
