Page 9: Camera Autotuning Message On First Start
This procedure is not invasive and not essential: if the operator forgets to apply the Lens Cap and just presses ok, the image quality is not affected and no danger is possible to the patient anyway. CenterVue DRS Operating Manual Pg. 9 of 59... -
Page 10: Preparing The Patient
There are no restrictions as to the selection of the patients undergoing DRS testing. The DRS is a non-mydriatic device (minimum pupil diameter 4 mm), so there is no need to dilate the subject’s pupil. Patient contacting parts are indicated in Figure 1. -

Page 17: Anterior Eye
Figure 12 - Retinal image acquired by the DRS 9.6 Anterior Eye In order to shoot a focused image of the anterior part of the eye, the patient’s head must be placed on the chinrest but with a distance of 3-5cm (2-3 fingers) between the patient’s forehead and the instrument forehead rest. -

General To enable a wired connection, plug a network cable into the DRS and wait a few seconds. Press “SET NETWORK” to refresh the network configuration. Most networks do not require the operator to set the IP address manually, but in case it’s needed, click on the Manual button and enter the IP address (mandatory), netmask (mandatory), gateway (optional) and DNS (optional). -

(e.g. \\drs-0010\shared). In case of complex networks, it may be necessary to insert the IP address of the DRS instead of its name (e.g. \\192.168.1.10\shared). In this case you might need to seek the support of your local IT staff. - Page 36 The Internal option is the easiest to set up, but the data is available only as long as the DRS is powered on and connected to the network. The Remote option might require additional information and special permissions (especially in complex networks) but the data is available even when the DRS is powered off or disconnected.

Backup tab allows full management of backup and restoration of the DRS entire database. To perform a data backup, simply connect a USB key or hard disk to the DRS and start the backup operation by pressing “Backup Data” button (see Figure 44). - Page 40 Remember to never modify your exams when reviewing them. Figure 45 - This view is shown when a previously stored backup is found. Note how the button is labeled “UPDATE BACKUP” instead of “START BACKUP”. CenterVue DRS Operating Manual Pg. 40 of 59...
- Page 41 Figure 48 - Restore mode Using the first mode (ERASE button) the current DRS exams and patient's data are overwritten by data of the selected backup source. In the second mode (APPEND button), the system properly recognizes identical patients and exams and executes a restoration into the DRS of the differences only.
- Page 42 An ambiguity between patients arises when they have the same name, no other useful information (like birth date, etc.) and they do have different database creation dates. For both backup and restore, a progress percentage informs the operator about the operation status. CenterVue DRS Operating Manual Pg. 42 of 59...

The Remote assistance button opens a remote connection that allows authorized service technicians to connect to the DRS.
- Page 45 Once confirmed with the OK button, the device contacts CenterVue servers and generates a random password and a port to connect to. These parameters must be sent to the service operator in order to connect. Figure 53 - Remote Assistance result The connection can be closed using the same button, which now has changed to Close Remote Assistance.
