Spare Parts for Medical Device Medical Equipment
■ Product Describe
Mindray UMEC12 Patient Monitor Encoder 050-002011-00 is a small
accessory for Mindray UMEC12 monitor. Its part number is
050-002011-00. It is the encoder of the main knob located on the
front of the monitor. It comes with a cable to connect and
communicate with the main board.
By rotating or pressing the external button, the signal is
transmitted to the encoder, and the encoder converts the signal
into a digital signal and transmits it to the main board. The main
board executes the command, thereby realizing the interactive
functions of the device such as menu navigation and parameter
adjustment.
The button can mainly select the previous page or the next page by
rotating left and right. After selecting the required option, press
the knob to enter the page. The button can be changed to select
different device functions, such as contrast, brightness, etc., and
different patients can also be selected. The button has a single
function and is very simple to operate, but it is used frequently
and is an accessory with a high repurchase rate. If you need to
purchase this accessory, please contact us CWT Technology HK
Limited.
■ Product Picture
■ Function
1. Rotation selection
The user selects the previous or next interface by rotating left
and right until the desired function (such as alarm limit, screen
brightness, volume) is selected.
2. Press to confirm
The user presses the button to select the corresponding function
and enter the next level page. It is a "confirmation" function
(equivalent to the "Enter" key)
3. Long press function
You need to press for 2 seconds to trigger the quick operation
(such as silent alarm, return to the main interface) to prevent
accidental touch.
4. Fault feedback
The main control board detects abnormal encoder signals and
triggers error prompts (such as "Control Knob Failure").

■ Notes on using accessories
1. Anti-static operation: The encoder circuit is sensitive. Please
wear an anti-static wristband before directly touching the encoder
to avoid damage.
2. Cable protection: When disconnecting the encoder cable from the
motherboard, do not pull the cable. Just press the buckle lightly
to detach.
3. Calibration: After replacing the encoder, please calibrate
whether the encoder function is normal. Path: Settings →
Maintenance → Control knob calibration
4. Cleaning and maintenance: Do not use alcohol to spray the button
surface directly. The liquid will enter the encoder through the gap
and damage the circuit, affecting the use of the encoder.
5. Dust and drop protection: Prevent dust from invading the
rotating mechanism; prevent the front panel from hitting when the
device is moving.
