4. Operating Instructions
4.1 Powering On/Off
Locate the ON/OFF switch on the microphone unit. Slide the switch to 'ON' to power on the microphone. Slide to 'OFF' when not in use to conserve battery life.
4.2 Sensitivity Enhancement (+10dB)
The microphone features a +10dB sensitivity enhancement switch. This can be used to boost the audio signal, which is useful in quieter environments or when recording from a distance. Switch to '+10dB' for enhanced sensitivity or '0' for standard sensitivity.
4.3 Low-Frequency Attenuation (200Hz)
The SGC-598 includes a low-frequency attenuation feature at 200Hz. This helps to reduce unwanted low-frequency noise such as wind noise, rumble, or air conditioning hum. Engage this feature when recording in noisy environments to improve clarity.
4.4 Low Power Indicator
The microphone is equipped with a low power indicator. When the battery level is low, this indicator will illuminate, signaling that the battery needs to be replaced soon to ensure continuous operation.

5. Maintenance
5.1 Cleaning
- Use a soft, dry cloth to clean the microphone body.
- Do not use liquid cleaners, solvents, or abrasive materials.
- Gently clean the windscreen with a soft brush if it accumulates dust or debris.
5.2 Storage
- When not in use for extended periods, remove the battery to prevent leakage.
- Store the microphone in a cool, dry place, away from direct sunlight and extreme temperatures.
- Use the provided carrying pouch (if applicable) to protect the microphone from dust and scratches.
6. Troubleshooting
6.1 No Sound Output
- Check Battery: Ensure a fresh 1.5V AA battery is correctly installed and the low power indicator is not active.
- Power Switch: Verify the microphone's ON/OFF switch is in the 'ON' position.
- Cable Connection: Confirm the 3.5mm audio cable is securely connected to both the microphone and the camera's microphone input.
- Camera Settings: Check your camera's audio input settings to ensure the external microphone is selected and input levels are appropriately set.
6.2 Poor Sound Quality (Hissing, Low Volume)
- Battery Level: A low battery can affect sound quality. Replace with a fresh battery.
- Sensitivity Setting: If audio is too low, try switching the +10dB enhancement to 'ON'. If there is excessive hiss, switch it to '0'.
- Low-Frequency Attenuation: Engage the 200Hz low-frequency attenuation if experiencing excessive rumble or wind noise.
- Proximity: Ensure the microphone is positioned close enough to the sound source.
- Camera Input Level: Adjust your camera's audio input gain. Avoid setting it too high, which can introduce hiss, or too low, which results in weak audio.
- Environmental Noise: The SGC-598 is designed to reduce ambient noise, but extreme noise levels may still affect recording quality. Try to record in quieter environments.
6.3 Microphone Not Mounting Securely
- Locking Wheel: Ensure the locking wheel on the microphone's base is fully tightened after sliding it into the hot shoe.
- Compatibility: Verify your camera's hot shoe is a standard size compatible with the microphone's mounting foot.
