The DR-1801UV supports both digital (DMR) and analog communication. The mode is typically set per channel during programming. You can observe the current mode (Analog or Digital) on the LCD screen.

• To switch between modes, navigate to the desired channel. The radio will automatically operate in the mode configured for that channel.
• For VFO (Variable Frequency Oscillator) mode, you may manually select the mode if supported by the firmware. Refer to advanced programming guides for VFO mode specifics.

2. Channel Selection

The radio has 1024 channels. Use the Up/Down arrow keys to navigate through programmed channels. Alternatively, you can enter a channel number directly using the keypad.

3. Volume Control

Rotate the Power/Volume knob clockwise to increase volume and counter-clockwise to decrease volume.

4. Transmitting and Receiving

• Receiving: When a signal is received on the active channel, the radio will automatically output the audio.
• Transmitting: Press and hold the Push-To-Talk (PTT) button on the side of the radio. Speak clearly into the microphone, holding the radio approximately 2-5 cm from your mouth. Release the PTT button to stop transmitting and return to receive mode.

5. SMS Function

The DR-1801UV supports sending and receiving text messages in digital mode. Access the SMS menu through the radio's interface. You can compose messages using the keypad and send them to other compatible DMR radios.

6. Emergency Alarm

The emergency alarm function can be activated via a pre-programmed customized key. When activated, the radio will emit a loud alarm sound and/or transmit an emergency signal to pre-defined contacts, depending on its configuration.

7. Customized Keys

The DR-1801UV features four customizable keys. These keys can be programmed via software to provide quick access to functions such as scan, monitor, emergency alarm, or power level adjustment. Refer to the programming software manual for detailed customization instructions.

8. DMO True 2 Time Slot

In Direct Mode Operation (DMO), the True 2 Time Slot feature allows two independent conversations to occur simultaneously on the same frequency. This doubles the communication capacity without requiring a repeater. Ensure both radios are configured for DMO and the correct time slot (Time Slot 1 or Time Slot 2) for communication.
