2. Connect the red wire to the positive (+) terminal of a 13.8 Vdc power supply and the black wire to the negative (-) terminal.
3. Ensure the power supply can provide sufficient current for the radio's maximum output power (60W).
4. Varoitus: Incorrect polarity or insufficient power supply can damage the radio.

5.4 Mikrofoniliitäntä

Plug the microphone's RJ-45 connector into the corresponding jack on the front panel of the radio.

6. Käyttöohjeet

6.1 Virta päälle/pois ja äänenvoimakkuuden säätö

• Virta päälle: Paina ja pidä painettuna POW -painiketta etupaneelissa.
• Virta pois: Paina ja pidä painettuna POW painiketta uudelleen.
• Äänenvoimakkuus: Rotate the outer knob (Volume) on the front panel clockwise to increase volume, counter-clockwise to decrease.

6.2 Kohinasalvan säätö

The squelch function mutes the speaker when no signal is received, eliminating background noise.

• Adjust Squelch: Rotate the inner knob (Squelch) on the front panel. Turn it clockwise until the background noise disappears. Turn it counter-clockwise to open the squelch and hear all signals, including noise.

6.3 Kanavan ja taajuuden valinta

The radio supports both VFO (Variable Frequency Oscillator) mode for direct frequency input and Memory Channel mode for pre-programmed channels.

• Vaihda tiloja: Paina VFO/MR button on the microphone or the corresponding function on the front panel.
• VFO-tila: Use the channel selector knob on the front panel or the microphone keypad to enter frequencies directly.
• Memory Channel Mode: Rotate the channel selector knob to cycle through the 200 programmable channels.

6.4 Frequency Step

The frequency step determines the increment when tuning. Available steps are 12.5 KHz, 20 KHz, and 25 KHz.

• Change Step: Refer to the programming software manual or the radio's menu system for step adjustment.

6.5 CTCSS/DCS-äänet

CTCSS (Continuous Tone-Coded Squelch System) and DCS (Digital Coded Squelch) tones are used to filter unwanted signals and allow private group communication. The radio supports 50 CTCSS and 1024 DCS codes.
