（2） Specific operational steps

Connecting Computers

In general, USB cables can be plugged and unplugged when the device is turned on, but it is recommended to connect them when the device is turned off: first turn off the device power, connect the B-type connector of the USB cable to the USB terminal of the device (make sure it is fully inserted and firmly connected), then connect the A-type connector to the USB port of the computer, and then connect the AC adapter and turn on the device power; If prompted to install a USB driver, you need to specify the USB driver that comes with the software that can connect and operate the device to complete the installation. After installation, you need to turn off the power and then turn it back on.

Attention: The USB communication of the device complies with the USB 2.0 standard; The device cannot be powered through a USB cable and needs to be connected to an AC adapter before use; When connecting/disconnecting USB cables, hold the connector tightly and do not pull or forcefully bend the cable to avoid cable breakage; Ensure that the cable length is sufficient to avoid connection failure or cable breakage caused by tension.

Connect the communication adapter

First, confirm that both the device and computer power are turned off (LED lights are not on). Connect the DC output plug of the AC adapter to the DC input terminal on the side of the device, and then connect the power plug of the AC adapter to a 100V (50/60Hz) AC socket; Note that the AC adapter (AC-A312F) that comes with the device must be used, and the plug must be fully inserted. Before plugging in or unplugging the DC output plug, make sure the power switch is turned off.

Turn on/off the power

Power on: When the power is turned off, press and hold the power button for about 1 second to turn on the power, and the LED light above the power button will turn blue; Note that when the power button is pressed, the LED light flashes to indicate that the AC adapter cannot be unplugged during the power on process.

Shutdown: Press and hold the power switch for about 3 seconds to turn off the power. The LED light will flash and then turn off; Similarly, the flashing LED light indicates that the AC adapter cannot be unplugged during the shutdown process.

Install target mask

First, pull out the sample rack in your own direction and keep it open. Then, pull out and remove the currently installed target mask or protective cover in your direction (the target mask is fixed by a magnet, and there are grooves on both sides of its contact surface with the device. Place your thumb and index finger in the grooves for easy removal; make sure the device is facing you when removing it, and remove it in a straight line to avoid tilting and damaging device components).

Then align the positioning holes of the target mask with the positioning pins of the device's target mask, and install the target mask onto the device (ensuring that the white coating surface on the inside of the target mask faces the device (CM-3700A-U Plus side), and that the text such as "SAV" on the surface faces up). Finally, restore the sample rack to its original position.

Attention: When performing zero calibration or white calibration, the target mask CM-A310 (SAV) must be used; If the target mask is installed in the wrong direction, it will not be installed correctly. It is necessary to check the direction and install it to ensure that there is no looseness or warping; Do not scratch the inner surface of the target mask (white coating surface) to avoid fingerprints or other dirt; The target mask may change color when exposed to light, and should be stored in the attachment storage space when not in use; Do not let the device have the target mask installed for a long time.
