2.5.2 T1 Docking Station and T1 Handle
The figure above shows the connection and relation among T1, T1 Docking Station and T1 Handle. They can be mutually
connected through 54-pin connectors. T1 is the core of the system, while T1 Handle and T1 Docking Station provide
extension of many functions.
When T1 is used with the T1 Handle alone, it can communicate with external parameter modules, and its interaction with
external modules is realized through the T1 handle converter board and T1 handle NIOS board.
When T1 is installed to the T1 Docking Station, it is connected to the T1-Dock interface power board through the T1-Dock
converter board, thus getting power from the T1-Dock interface board. Besides, T1 can be connected with external devices
through the USB connector, external device connector (Mini DB15), VGA, and network connector on the Docking Station.
When T1, the T1 Docking Station and the T1 Handle are used together, all the functions described above are provided.

3 Unpacking and Installation
This chapter provides information you need to install a patient monitor ready for use.
WARNING
The equipment shall be installed by personnel authorized by Mindray. The software copyright of the equipment is solely owned by Mindray. No organization or individual shall resort
to altering, copying, or exchanging it or to any other infringement on it in any form or by any means without
due permission.
Devices connected to the equipment must meet the requirements of the applicable IEC standards (e.g. IEC 60950
safety standards for information technology equipment and IEC 60601-1 safety standards for medical electrical
equipment). The system configuration must meet the requirements of the IEC 60601-1-1 medical electrical
systems standard. Any personnel who connect devices to the equipment’s signal input/output port is
responsible for providing evidence that the safety certification of the devices has been performed in accordance
to the IEC 60601-1-1. If you have any question, please contact Mindray.
If it is not evident from the equipment specifications whether a particular combination with other devices is
hazardous, for example, due to summation of leakage currents, please consult the manufacturers or an expert in
the field. A determination must be made that the proposed combination will not negatively affect the devices
themselves or the patient's safety.
3.1 Unpacking and Checking
Before unpacking, examine the packing case carefully for signs of damage. If any damage is detected, contact the carrier or
Mindray.
If the packing case is intact, open the package and remove the equipment and accessories carefully. Check all materials
against the packing list and check for any mechanical damage. Contact Mindray in case of any problem.
WARNING
When disposing of the packaging material, be sure to observe the applicable waste control regulations and keep
it out of children’s reach.
The equipment might be contaminated during storage and transport. Before use, please verify whether the
packages are intact, especially the packages of single use accessories. In case of any damage, do not apply it to
patients.

NOTE
Save the packing case and packaging material as they can be used if the equipment must be reshipped.
3.2 Preparation for Installation
3.2.1 Preparation for Installation Site
1. Ensure that the site meets all safety, environmental and power requirements
2. Check that required power sockets are available.
3. Check that a network connector is available if the monitor needs to be connected to the wired network.
WARNING
Use only the power cord or DC adapter provided with the system.
Environmental Requirements
To avoid explosion hazard, do not use the equipment in the presence of flammable anaesthetics, vapors or liquids. The
environment where the monitor will be used should be free from vibration, dust and corrosive substances. If these
