Chapter 3 - How to...

3 How to...

Before using the system and capturing images, you should be familiar with all the features and capabilities of
the system.

3.1 Get started

CAUTION

Read the warnings and cautions before using your device.

Your device should be left in standby mode at the end of each working day.

Note

The device automatically logs out when the device is not in use.

3.1.1 Switch on each day

The image server and scan head must be switched on each day for the device to operate.

3.1.1.1 Switch on the image server

The review, admin and storage services run on the image server. You do not need to login to the image server
as the server only needs to be switched on.

Your image server may also be used as a browser-based review client.

1. Check that the power supply is switched on.

2. Switch on the image server.

Note

If it seems the image server is not working, check the monitor is switched on then confirm the image server
is switched on.

3.1.1.2 Switch on the scan head

CAUTION

Only use the fabric cover when the scan head is powered off or in standby mode. Remove
the fabric cover before operating the scan head.

The scan head will move when the alignment system is being centered. This will happen
automatically when the device is switched on and when the alignment system is re-
centered between patient sessions. You should ensure that there is space around the
scan head to allow free movement.

The scan head should be left in standby mode at the end of each working day and so will need to be started
each day.

1. Remove the scan head fabric cover.

2. Check the image server is switched on and fully started up before switching on the scan head.
