Connect your external VHF/UHF antenna to the Antenna Jack (16) on the rear of the radio. Ensure the connection is secure. Warning: Do not transmit without an antenna connected to avoid damaging the radio.
- Connecting the GPS Antenna:
If using GPS/APRS functionality, connect the GPS antenna to the GPS Antenna Jack (18).
- Connecting the Speaker Microphone:
Plug the speaker microphone cable into the Microphone Speaker Jack (14) on the front of the radio unit.
- Potència de connexió:
Connect the supplied DC power cable to the Power Input (19) on the rear of the radio. Connect the other end to a suitable 13.8V DC power source (e.g., vehicle battery or regulated power supply). Ensure correct polarity.
- Optional External Speaker:
If desired, an external speaker (like the Radioddity RS58) can be connected to the external speaker jack (usually a 3.5mm mono jack, not explicitly numbered but typically present on mobile radios). This allows for clearer audio in noisy environments.

Image: The radio's bright color display showing VFO mode and dual band frequencies.
The TFT Display (11) provides essential information such as current frequency, channel number, operating mode (analog/digital), signal strength, and various status indicators. The display supports VFO (Variable Frequency Oscillator) mode for direct frequency input and Channel mode for pre-programmed channels.
Dual Band and Dual Mode Operation
- Banda dual: The radio supports both VHF (136-174 MHz) and UHF (400-470 MHz) frequencies. You can switch between bands using the B/E Key (7) or through menu options.
- Mode dual: Seamlessly switch between analog and DMR Tier II digital operation. The radio automatically detects the mode of incoming signals in some configurations or can be manually set.
- Dual Standby: The radio can monitor two different frequencies simultaneously. If a signal is detected on either frequency, the radio will switch to that channel.
Selecció de freqüència i canal
- Mode VFO: Use the Rotating Knob (9) or the keypad on the speaker microphone to directly input frequencies.
- Mode de canal: Rotate the knob to scroll through pre-programmed channels.
- Emmagatzematge de memòria: The radio supports 4000 channels and 300,000 contacts. Channels and contacts can be programmed via software.

Customizable Keys (P1-P7)
The radio unit has 3 customizable keys (P1-P3) and the speaker microphone has 4 (P4-P7). These keys can be programmed for various functions (e.g., power level, scan, monitor, zone switch) via the programming software. Both short press and long press options are available for each key.
Ajust de volum i silenciador
- Volum: Use the Volume / Squelch Key (5) and Rotating Knob (9) to adjust the audio output level.
- Suprimir: The squelch function mutes the speaker when no signal is present, eliminating background noise. Adjust the squelch level via the menu or a dedicated function key to open the squelch for weak signals or close it for noisy environments.
Transmetre i rebre
- Recepció: When a signal is received, the Indicator (12) will light up, and audio will be heard through the speaker.
- Transmetent: Select your desired frequency or channel. Press and hold the PTT Key on the speaker microphone to transmit. The Indicator will change color (e.g., red) during transmission. Speak clearly into the microphone. Release the PTT key to stop transmitting and return to receive mode.
Manteniment
- Neteja: Use a soft, dry cloth to clean the radio's exterior. Do not use harsh chemicals or abrasive cleaners.
- Ventilador de refrigeració: Ensure the Cooling Fan (17) on the rear of the unit is not obstructed to allow for proper heat dissipation, especially during prolonged transmissions. Periodically check for dust buildup and gently clean if necessary.
- Connexions: Regularly check all cable connections (power, antenna, speaker mic) to ensure they are secure and free from damage.
- Emmagatzematge: Quan no la feu servir durant períodes prolongats, guardeu la ràdio en un lloc fresc i sec, allunyat de la llum solar directa i de temperatures extremes.
