RDU, the four LED’s will blink and buzzer will sound on SEU & RDU., after that
the communication is ready, the content of display is same on SEU & RDU.

9. Customizing Settings
When power has been connected, the SEU and RDU will begin to monitor the
CO2 concentration and the temperature. In order to the get the timely alarm safety
information and meet the personal requirements, It is advisable to set up the
customizing parameter when necessary.
Temperature ºC/ºF:
Using the DIAG function:
1. Press Mode until the “DIAG” icon flashes
2. Press Enter, the four LED’s will blink on the SEU and the buzzer will
sound
3. The four LED’s will blink and buzzer will sound simultaneously on
the RDU
Setting the First Alarm parameter:
1. Press Mode until the “AL1” icon flashes
2.Press Enter, the “AL1” icon shows on LCD
3. Press Mode to go through “
0.5%,1%,1.5%,2%
” alarm level
4. Press Enter again to save the setting after selection
Setting the Second Alarm parameter:
1. Press Mode until the “ AL2” icon flashes
2. Press Enter, the “AL2” icon shows on LCD
3. Press Mode to go through “
1.5%,2%,2.5%,3%,3.5%,4%
” alarm level
4. Press Enter again to save the setting after selection
Notes: The second alarm level should be higher than the first alarm level
when setting with the alarm level parameter.
Using the CALI function:
1. Press Mode until the “CALI” icon flashes
2. Press Enter, the “CALI” icon shows on the LCD
3. Press and hold Mode for at least 10 seconds. The “CALIBRATING”
icon will flash. The calibration will be done automatically. After 10
minutes the LCD will display “Pass” or “Fail”. If “Fail”, please try
again.
Notes: When do the calibration, it is suggested to take SEU outside, using
the ambient gas for calibration, waiting around 10 minutes until the CO2
reading of SEU doesn’t change, then use the 380-420 ppm as the
standard CO2 reading. Calibrating the unit according to “CALI” mode
instruction, user should not breathe toward to SEU during the calibration
process, as the CO2 from the user will affect the CO2 reading of SEU.
Using the ReFactSet function:
1. Press Mode until the “ReFactSet” icon flashes
2. Press Enter, and then press Mode to choose either “Yes” or “No”
3. Press Enter again to save the setting after selecting
Note: If the user sets the data or calibrates the sensor incorrectly, use the
ReFactSet (recover the factory Setting) to come back the default factory
setting.
