Aranet4 is a complicated electronic device with self-diagnostic possibilities. Sometimes error messages can appear on display. What to do if you met one?

Before proceeding with the further recommended solution steps, please do:

Take out batteries from the sensor and wait about 1 hour.
Put batteries back observing the correct polarity (both batteries with "+" to the left side).
Check Aranet4 firmware version and update if offered: https://forum.aranet.com/all-about-aranet4/how-can-i-update-aranet4-device-firmware/
If the problem persists, find the error code visible on the screen in the table below and follow recommendations.

Error Ox8002 code does not disappear. Firmware is up to date. Removed batteries for 1 hour + and still error code. Tried to calibrate, but would not work.

I have not dropped it or done anything to cause it to malfunction. Please advise. Perhap send RMA & return info. Will there be a cost?

Thank you,

I am using sensor at my school to monitor ventilation. If I send my monitor in for repair do you have loaner's available? I am so upset about this.
