The LCD display complies with the China Compulsory Certification
(GB4943.1-2001, GB9254-2008, GB17625 1-2012). CCC China only.
NOTE: The following symbols (required by China law only) are
representative of what you may see on your equipment. The number
in the symbol indicates the EFUP period in years, as explained below.
Check the symbol on your equipment for its EFUP period.This symbol
indicates the product contains hazardous materials in excess of the
limits established by the Chinese standard (January 2016): GB/T
26572 Requirements for Concentration Limits for Certain Hazardous
Substances in Electronic Information Products. The number in the
symbol is the Environment-friendly User Period (EFUP), which indicates
the period during which the hazardous substances or elements
contained in electronic information products will not leak or mutate under
normal operating conditions so that the use of such electronic information
products will not result in any severe environmental pollution, any bodily
injury or damage to any assets. The unit of the period is “Year”. In order
to maintain the declared EFUP, the product shall be operated normally
according to the instructions and environmental conditions as dened in
the product manual, and periodic maintenance schedules specified in
Product Maintenance Procedures shall be followed strictly. Consumables
or certain parts may have their own label with an EFUP value less
than the product. Periodic replacement of those consumables or parts
to maintain the declared EFUP shall be done in accordance with the
Product Maintenance Procedures. This product must not be disposed
of as unsorted municipal waste, and must be collected separately and
handled properly after decommissioning.

●
Make sure to carefully read the User Manual that accompanies the patient display prior
to using this display to ensure proper operation of the devices.
●
Note that, excluding those cases where a responsibility for legal compensation is
recognized, the manufacturer shall bear absolutely no responsibility for damage to this
product by a customer or a third party that results in improper use from the ignoring of the
contents entered in this Technical Manual.
●
Follow the instructions below for safe use of the LCD Display.
- To avoid electric shock, do not attempt to remove any cover or touch the inside of the
LCD Display. Only a qualied service technician should open the LCD Display case.
- Do not insert metal objects or spill liquid into the LCD Display through cabinet slots.
They may cause accidental fire, electric shock or failure. In case a foreign object was
inserted or water has penetrated, unplug the AC cable and have the LCD Display serviced.
- Do not cover or block the vent holes in the case.
- Disconnect the power plug from the AC outlet if you will not use it for an indenite period
of time.
- Do not apply pressure to the screen. The LCD Display is very delicate.
● No modification of this equipment is allowed. Safe use of the equipment cannot be
guaranteed if unauthorized modications are made to the display.
● If this equipment is modied, appropriate inspection and testing must be conducted to
ensure continued safe use of the equipment.
● OPERATOR must not touch the enclosure and PATIENT simultaneously.
● Do not connect to multiple socket outlets.
● To avoid the risk of electric shock this equipment must only be connected to a supply
mains with protective earth.
●
If your LCD Display uses an AC/DC Adapter: Only use the Adapter, which accompanied
this device. Use of another AC/DC Adapter may cause a malfunction or electrical shock
or re hazard.
●
If your LCD Display does not operate normally. In particular, if there are any unusual
sounds or smells coming from it-unplug the AC cable immediately and contact the
manufacturer, or authorized service center.
Safety Precautions

●
POWER SUPPLY. The device must be connected to a properly installed power outlet
with protective earth contacts only. If the integrity of the protective earth conductors is in
doubt, disconnect the LCD Display from the power line and use it with the battery option if
available). If the installation does not provide for a protective earth conductor, disconnect
the LCD Display from the power line. All devices in a system must be connected to the
same power supply circuit. Devices which are not connected to the same circuit must be
electrically isolated when operated.
●
GE is responsible for the effects on safety, readability, and performance of the equipment
only if:
-
Assembly operations, extensions, readjustments, modications, servicing, or repairs are
carried out by authorized service personnel.
-
The electrical installation of the relevant room complies with the requirements of the
appropriate regulations.
-
The equipment is used in accordance with the instructions for use of the patient display
and this Technical manual.
●
Grounding reliability can only be achieved when the equipment is connected to an
equivalent receptacle marked “Hospital Only” or “Hospital Grade”.
●
DO NOT position the LCD Display so that it is difficult to operate or to connect and
disconnect the AC power cord.
●DO NOT touch the patient simultaneously with connection or disconnection of cables.
●Installation and OSD adjusting should only be carried by manufacturer trained and
authorized personnel.

telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV
broadcast cannot be predicted theoretically with accuracy. To assess the elec

environment due to fixed RF transmitters, an electromagnetic site survey should be
considered. If the measured field strength in the location in which the LCD display for
Healthcare Applications is used exceeds the applicable RF compliance leve
l above, the LCD
display for Healthcare Applications should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be n ecessary, such as reorienting or
relocating the LCD display for Healthcare Applications.

Recommended separation distances between portable and mobile RF communications
equipment and the LCD display for Healthcare Applications for all EQUIPTMENT AND
SYSTEMS that are not LIFE-SUPPORTING
The LCD display for Healthcare Applications is intended for use in an electromagnetic
environment in which radiated RF disturbances are controlled. The customer or the user of the
LCD display for Healthcare Applications can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications
(equipment) and the LCD display for Healthcare Applications as recommended below
according to the maximum output power of the communications equipment.

5. Potential Equalization Connector
If you intend to mount the display on the wall (ceiling), we strongly recommend that you use only
UL approved wall (ceiling) mount kits with attached M4*12 mm screws that can hold more than
the display weight, and that you ensure it is securely and safely installed. (VESA mounting for
75 mm x 75 mm and 100 mm x 100mm).
If you use a non-UL approved wall (ceiling) mount kit, there is a safety risk that the display
may fall from the wall (ceiling) due to an improper attachment through the use of wrong length
screws. Refer to GE manuals CARESCAPE monitors' user's manual and supplemental
information manual and to the CARESCAPE Modular Monitors Mounting Solutions for more
information on approved mounting solutions and hazards associated with improper mounting.
Note:
All units are shipped with pre attached 75 mm x 75 mm VESA Plate.
Display is equipped with an equipotential connector.

Pressing the power button for more than one second, and then releasing, turns on the
color LCD display. Pressing the same button again turns the display off. The display shall
recall the On/Off status even if the external power source is removed.
•
When the OSD control dial is pressed while the display is on, the OSD display window
appears on screen.
• OSD stands for On Screen Display. Its function is to display information for conguring
the display. The OSD display window cannot be activated if the display is presently
displaying an error message such as "NO SYNC". The user must wait for the message to
extinguish. Error messages are self-generated by the display and indicate invalid video
