- Instrument Connection: Use one end of the CM-12 instrument cable to connect your guitar (or other instrument) to the INPUT jack of the R-14 pedal.
- Amplifier Connection: Use another instrument cable (not included, or the other end of the CM-12 if used for pedal-to-amp) to connect the OUTPUT jack of the R-14 pedal to your amplifier's input.
- Power On: Once all connections are secure, connect the power adapter to a wall outlet. The pedal's indicator light should illuminate when engaged.

7. Operating Instructions
Once set up, operate the JOYO Atmosphere R-14 pedal as follows:
- Engage/Bypass: Press the footswitch to toggle the reverb effect ON or OFF. The LED indicator will show the pedal's status.
- Select Reverb Type: Rotate the Reverb Type Selector knob to choose one of the 9 available reverb algorithms. Experiment with each type to find the desired sound.
- Adjust Reverb Parameters: Use the MIX, DECAY, TONE, and MOD knobs to fine-tune the selected reverb effect.
- Start with MIX at 12 o'clock and adjust to blend the reverb with your dry signal.
- Increase DECAY for longer reverb tails, decrease for shorter ones.
- Adjust TONE to brighten or darken the reverb.
- Explore the MOD knob's effect, as its function varies slightly with each reverb type.
- TRAIL Function: Set the TRAIL switch to ON if you want the reverb tail to continue decaying naturally after bypassing the effect. Set it to OFF if you prefer the reverb to cut off immediately.

| No sound when pedal is engaged. | Incorrect cable connection, no power, pedal bypassed. | Check all cable connections. Ensure power adapter is connected and working. Press footswitch to engage pedal. |
| Excessive noise or hum. | Poor quality power supply, ground loop, faulty cable. | Use a regulated 9V DC (center negative) power supply. Try a different power outlet. Ensure cables are fully inserted and not damaged. |
| Reverb cuts off abruptly when bypassed. | TRAIL switch is set to OFF. | Set the TRAIL switch to ON for natural reverb decay after bypass. |
| Cable not working. | Damaged cable, improper connection. | Inspect cable for visible damage. Ensure plugs are fully inserted into jacks. Try a different cable to isolate the issue. |
