**NOTE:** The switch is commom with the Bootes-1A Alta CCD, which will be also power cycled if you do this. Therefore, you should also consider stopping the alta driver before and restarting it after the former action. | **NOTE:** The switch is commom with the Bootes-1A Alta CCD, which will be also power cycled if you do this.

**NOTE:** as this switch is common with Bootes-1B mount, you should check the mount as well. If observing, consider paring the mount in advance to avoid possible problems while the mount is being reset. | **NOTE:** as this switch is common with Bootes-1B mount, you should check the mount as well.

The northern (nearer to the domes) sensor seems to have a malfunctioning DEU (drop evaluation unit), although the drops (well, screwdriver strikes) get detected well at the frame, the DEU does not react. The unit should be revised soon. | The northern (nearer to the domes) sensor seems to have a malfunctioning DEU (drop evaluation unit), although the drops (well, screwdriver strikes) get detected well at the frame, the DEU does not react.
