    The recorder can use SDHC and SDXC memory cards. Titley Scientific highly recommends Sandisk® Extreme and Sandisk® Ultra SD cards, these cards have been tested with the Chorus and are recommended due to their reliable performance and low power consumption. Using other brands and models may result in reduced battery life or device malfunction and are not recommended.

    USING THE CHORUS The Chorus is designed for fast and easy deployment. Before you start recording you must first set your current time zone (see Time zone). The clock will be automatically set when the GPS obtains a signal. We also highly recommend you check for firmware updates (see Update Firmware).

In this case there is no need to adjust the microphone settings on the Chorus itself. 6. Wait for the GPS receiver to obtain a location. This normally only takes a couple of minutes but can take longer if there are trees or dense clouds obstructing the signal.

  • Page 29: Passive Deployment Considerations

    PASSIVE DEPLOYMENT CONSIDERATIONS WEATHERPROOFING The Chorus is designed as a weatherproof recorder, which means the recorder can be left in the field during rain, sunshine and snow without any additional weatherproofing. However, if the device is left in the rain, please consider the following advice: 1.

  • Page 30: Mounting & Placement

    Also consider insect noise when choosing a location, insects close to the recorder can generate a lot of unwanted noise files. We recommend that the Chorus is mounted vertically (refer to the section on weatherproofing) so that any rain water runs off the microphone/s and doesn ’t settle on the element/s.
