4. Recorder Operation

4.1. Starting Up and Shutting Down

To start the recorder, use the front panel power switch.

NexLog 740 DX-Series Recorder: The power switch is behind the locked door on which the display is mounted on touch screen units, and behind the blank front panel door on non-touch screen units.

NexLog 840 DX-Series Recorder: The power switch is the keyhole. Insert the key into the keyhole and turn it clockwise.

Important

Do not hold the switch or turn the key for more than one second.

To shut down the recorder, you can perform a controlled shutdown or a forced shutdown. In most circumstances, you should only perform a controlled shutdown. This allows the recorder to close all open files and complete current database operations before shutdown. A forced shutdown can result in corrupted files and loss of data. It can also damage any archive media in the process of being written, and possibly leave either gaps or duplications in your archives. (In addition, Eventide strongly recommends using the recorder with a UPS to allow a controlled shutdown in the event of a power failure.)

Warning

A forced shutdown can result in corrupted files and loss of data.

To perform a controlled shutdown of the recorder from the Front Panel:

  • Press Setup (Gear icon)

  • Press Setup again to open the side menu.

  • Select System.

  • Select Power Off.

  • Select Shutdown, enter a reason and respond “OK” to the prompt.

If for some reason, it is not possible to use this standard method to perform a shutdown, a controlled shutdown can still be accomplished using the following, somewhat riskier, alternative.

Use the power switch to initiate a controlled shutdown by engaging the switch for up to one second.

Eventide does not recommend forcing a shutdown, but if it becomes necessary follow these steps.

Warning

A forced shutdown can result in corrupted files and loss of data.

To perform a forced shutdown of the recorder:

  • Engage the power switch for 10 seconds until it shuts down.

  • An alternative way to perform a forced shutdown is to turn off the power supplies from the back panel, or unplug the power supplies.
