Product and Functional Description

The Stemi 305 cam stereo microscopes with integrated camera are designed for magnifying spatial observation of small objects. Additionally, they allow visualization of the objects in a live image on the monitor and recording of digital images and videos.
The visualized images of the Stemi 305 cam may only be used for documentation, laboratory and research purposes. The images are not intended for the direct generation of diagnostic results. With the Stemi 305 cam stereo microscopes, the digital images from the integrated camera can be transmitted via digital networks or transferred directly “one-to-one” to digital end devices (PC, laptop, tablet computer, etc.).
The Stemi 305 cam is available in two versions:

• Stemi 305 cam W body with integrated Wi-Fi and Ethernet camera can transfer digital images both wirelessly and wired. Stemi 305 cam W body is only available in certain countries for which it has radio license .
• Stemi 305 cam E body with Ethernet camera (without Wi-Fi function) is available worldwide.

The transmission of digital images is only possible via a cable-based Ethernet network.

The Ethernet socket on the network router is defective.| Plug the cable into another
Ethernet socket on the router.
The Ethernet interface on the digital end device is defective.| Check this by connecting another digital end device.
The digital end device is not correctly connected to the network router| Check this by changing the Ethernet cable, by plugging the digital end device into another LAN socket on the router, by connecting the digital end device via Wi- Fi, or by changing the digital end device.
Stemi 305 cam W body is connected via Wi-Fi. The live image is unstable or delayed.| Too high Wi-Fi load in the environment
The Wi-Fi signal is too weak.| Reduce the distance between Stemi 305 cam and the digital end device.
Choose a Wi-Fi cannel in the 5 GHz band.
Connect the digital end device via Ethernet.
The status LED of Stemi 305 cam W body lights up continuously, but the Wi-Fi SSID is not visible in

not detected in Labscope.| On the configuration page, the wrong Wi-Fi SSID was selected, or the password was not entered correctly.| Connect Stemi 305 cam W via Ethernet [ 18].
Correct the SSID and the password.
Alternatively: Reset Stemi 305 cam [ 28].
The SSID of the WLAN network contains a dot, e.g.: “TP-Link_02.4G”| Rename the existing WLAN so that the SSID only consists of letters, digits, hyphens and
underscores, e.g.: “TPLink_02_4G”
The live image of Stemi 305 cam W body appears twice in Labscope.| Stemi 305 cam W is double connected to a router (via Ethernet cable AND via the router’s Wi-Fi network)| This is not an error. To remove one live image, the Ethernet cable can be disconnected, or
the WLAN mode can be changed to “WLAN Access Point”

Decommissioning and Disposal

This chapter contains information on the decommissioning and disposal of the microscope and its expansions/components or accessories.
8.1 Decommissioning
If the microscope and its components are not used for an extended period of time such as several months, they should be shut down completely and secured against unauthorized access.
DANGER
Electric injury due to live parts
When the microscope and its components are still switched on, coming in contact with live parts can lead to electric shock or burn.

• Switch off the microscope and its components prior to opening or cleaning.
• Disconnect live parts from the power supply.

Procedure

1. Switch off the microscope.
2. Pull the power supply plug.

8.2 Transport and Storage

The following regulations must be observed before and during transport:

• Use devices (e.g. handles, fork lifts or hand pallet trucks) to transport the microscope safely to the installation room. The microscope may only be transported in air-suspended vehicles.
• Devices for transporting the microscope must be rated to handle its full weight and dimensions.
• Moving parts must be secured during transport to prevent them from slipping or tipping over.
• Avoid rocking the transport boxes back and forth.
• Note the weight information on the package and on the shipping document.
• Where possible, the original packaging must be used for shipping or transport.

Allowable Temperature

Allowable temperature during transportation to or between sites:

• Between -40 °C and 70 °C

Allowable temperature during storage at site:

• Between 10 °C and 40 °C
• Relative humidity less than 75 % at 35 °C

Info
24 hours before installation of the microscope it is required that the boxes are at recommended room temperature to avoid ingress of humidity, which is harmful to optical paths, and to ensure effective stability of the microscope during installation and testing.
Info
Detailed information on transport and storage is available from your ZEISS Sales & Service Partner.

8.3 Disposal
The microscope and its components must not be disposed of as domestic waste or through municipal disposal companies. They must be disposed of in accordance with applicable regulations (WEEE Directive 2012/19/EU). ZEISS has implemented a system for the return and recycling of devices in member states of the European Union that ensures suitable reuse according to the EU Directives mentioned.
ZEISS introduced a procedure for the return and recycling of the instruments within the member states of the European Union which ensures suitable recycling procedures conforming to the EU directives.
For more information on disposal and recycling please consult your ZEISS Sales & Service Partner.
The microscope may not be disposed of in the household waste or through municipal waste disposal services. If the microscope is resold, the seller shall be obliged to inform the buyer that the microscope must be disposed of in accordance with the regulations.
The customer is responsible for decontamination.
8.4 Decontamination
A decontamination statement must be submitted before returning any used objects to the ZEISS location.
If reliable decontamination cannot be guaranteed, the hazard must be marked according to applicable regulations. In general, a well-visible warning sign must be affixed to the article itself and to the outside of the packaging, together with detailed information on the type of contamination.
