Transmission
To communicate, all radios in your group must be set to the same channel. Briefly press the MONI key to enable the Monitor feature in order to
make sure that the frequency is not busy, and then press the [PTT] key. Release the [PTT] key to receive. Only one user at a time can talk during
radio communications. Therefore, it is important not to transmit when you are receiving a communication and use the transmission mode
sparingly to allow other users to talk. Transmission consumes a significant amount of energy and should therefore be used sparingly to prolong
the battery life. If you are unable to contact a station that you have no problems in receiving, the station may be using CTCSS tones or DCS
codes.
Monitor
The Monitor feature is for excluding (opening) the Squelch, in order to listen to signals that are too weak to keep the Squelch permanently
opened. Hold down the MONI key to enable such function.
Scan
This function can only be activated by programming software. To enable the scan function, all 16 channels must be programmed. When the radio
is turned on, press and hold the and keys at the same time, and scanning will start automatically. Whenever any signal is detected, the scan
stops on a busy channel. If you press and hold PTT, you will send on the latest busy channel. Press any function key to exit the scanning state.
