4. Configuração
4.1 Instalação da bateria
- Certifique-se de que o transceptor esteja desligado.
- Localize a tampa do compartimento da bateria na parte traseira da unidade.
- Deslize ou desencaixe a tampa para abrir o compartimento.
- Insert one AAA battery (sold separately) according to the polarity indicators (+/-) inside the compartment.
- Feche bem a tampa do compartimento da bateria até ouvir um clique.
4.2 Fixação da Antena

5. Instruções de operação
5.1 Ligar/Desligar e Ajuste de Volume
- To turn on: Rotate the Power/Volume knob clockwise until a click is heard and the display illuminates.
- To turn off: Rotate the Power/Volume knob counter-clockwise until a click is heard and the display turns off.
- To adjust volume: Rotate the Power/Volume knob while the unit is on. Clockwise increases volume, counter-clockwise decreases it.
5.2 Seleção de Canal
- Use the Up/Down arrow buttons to select your desired communication channel (1-47).
- Ensure all transceivers in your group are set to the same channel for communication.
5.3 Transmissão e Recepção
- Para transmitir: Press and hold the PTT button. Speak clearly into the microphone (located near the speaker grille). Release the PTT button when finished speaking.
- Para receber: Ensure the PTT button is not pressed. The transceiver will automatically receive signals on the selected channel.
5.4 Função de Monitoramento
- Press the 'Monitor' button to temporarily open the squelch. This allows you to hear very weak signals or background noise on the current channel, which can be useful for checking channel activity.
- Release the 'Monitor' button to return to normal squelch operation.
5.5 Group Mode
- The 'Group' button is used to manage group communication settings. Refer to the full user manual for detailed instructions on setting up and using group codes (CTCSS/DCS tones) for private conversations within a larger group.
6. Manutenção
6.1 Limpeza
- Wipe the transceiver with a soft, dry cloth.
- Para sujeira persistente, use um pano levemente umedecido.ampEnxágue com água e detergente neutro e, em seguida, seque com um pano.
- Não utilize produtos químicos agressivos, solventes ou produtos de limpeza abrasivos.
6.2 Armazenamento
