[. . . ] The transceiver has 8 channels and 38 CTCSS (Continuous Tone Coded Squelch System) codes. If someone else is using the same channel as yours, and you do not want to hear that person, you can select another channel or use the CTCSS feature. You can talk with a person who has the same transceiver if both are tuned to the same channel and/or CTCSS code. 7. The symbol flashes when battery is low.
