Additional notes:

Gain LED indicator
The ZM-1 and ZR-1 are a digital solution, therefore the Gain knob does not affect tonal characteristics of the recorded input, unless the signal is clipping, which may cause distortion on the signal.
The gain LED indicator will blink if the signal is clipping, in this situation lower the gain or place the ZM-1 microphone further away from the sound source.

For recording, it is ideal to set the Gain knob at minimum to avoid clipping. Increasing or decreasing the gain does not affect tonal characteristics of the signal.
