Hello! If your AED is unresponsive when powered on, it may affect your emergency use. Please immediately follow the steps below to troubleshoot:

① Make sure the battery is installed correctly (open the battery compartment of the host and check whether the battery clip is fastened tightly and not loose or misplaced);

② Replace the backup battery (if available) and try to restart the device (note that the battery model must match the device and use a dedicated lithium battery);

③ If there is still no response, it means that there may be a hardware failure in the host or battery. Do not disassemble it yourself. Please contact the brand after-sales service immediately and replace it with a spare AED for emergency use to avoid affecting emergency needs.

Hello! If the AED displays an "X" or a flashing red light, it is a fault alarm signal and requires the following processing:

① Follow the customer service instructions to troubleshoot (if the electrode pad is not connected, reconnect it tightly; if the battery is expired, replace it). After troubleshooting, restart the device to see if the fault is eliminated.

②If the fault persists, it means the device requires professional repair. Please stop using it immediately and contact after-sales service. At the same time, record the time of the fault and the flashing frequency to facilitate after-sales service to quickly locate the problem.

Hello! Screen issues may affect the viewing of "electrode placement instructions" and "heart rhythm analysis results" during emergency treatment. Please address these issues based on the specific situation:

① Screen distortion/black screen: First check the battery power supply (replace the battery and restart the computer to rule out insufficient power). If the problem persists, the screen cable may be loose or damaged. Do not knock or press the screen. Contact after-sales service for a replacement.

② The screen is inverted/touch screen is not working: Enter the device's "Setting Mode" (some models can be entered by long pressing the "Menu Key", such as Jiuxin Medical AED), and try to restore the "Screen Display Default Settings" and "Touch Screen Calibration"; if the calibration does not work, it means that the system or touch screen hardware is faulty and after-sales service is required. During this period, a spare AED will be used instead.

Hello! The AED's voice instructions are crucial for first aid (e.g., "Please apply electrodes" or "Analyzing heart rhythm"). Abnormal sounds require urgent attention:

① No sound: Check if the device volume is accidentally set to "mute" (some models can be adjusted by long pressing the "volume button" and the screen will display the volume icon). If the volume is normal but there is still no sound, it may be a speaker failure;

② Abnormal sound (noise/stuttering): Restart the device first to eliminate temporary system interference. If the abnormality persists, it indicates that the speaker or audio module is faulty. In all cases, you need to stop using the device and contact after-sales service. At the same time, ensure that the backup AED sound function is normal to avoid being unable to obtain voice guidance during emergency treatment.

Hello! Damage to the AED main unit may affect the device's sealing (such as waterproofing and dustproofing) or internal structure. Please handle it with caution:

① If the damage is only scratches on the outer shell, with no loose interfaces or exposed internal parts, first check the device's self-test function (after turning it on, wait for the "Self-test passed" prompt, which is usually a solid green light). If the self-test is normal, you can temporarily use it, but you need to record the damage and contact after-sales service to replace the outer shell later.

② If the damage causes the interface to become loose (such as deformation of the electrode slot) or internal parts to be exposed, do not use the device. Immediately contact after-sales service for a safety assessment and replace it with a spare AED to avoid connection failure during emergency treatment.

Hello! Expired AED batteries can cause unstable power supply or even prevent the AED from starting. This is a mandatory replacement item.

① Immediately remove expired batteries and replace them with new batteries that are within the validity period and that match the device model (pay attention to the direction of the positive and negative poles when replacing to avoid damaging the host by installing them in reverse);

② Record the "Installation Date" and "Expiration Date" of the new battery (marked on the label inside the battery compartment), and check the battery power regularly (e.g. once a month) as required by the device; ③ Please dispose of expired batteries according to "hazardous waste" regulations (do not discard them at will). Please contact us for consultation.

Hello! Failure to connect the electrodes will cause the AED to be unable to analyze the heart rhythm. Please follow the steps below to troubleshoot:

① Check whether the electrode plug matches the host slot (different brands of AED electrode plugs have different shapes, such as the Medtronic AED electrode plug is a "flat double plug" and cannot be mixed);

② Clean the plug and slot (use a dry cloth to wipe off dust and stains on the surface to avoid poor contact), reinsert the electrode plug, and make sure you hear a "click" locking sound;

③ If the message "Connection Error" is still displayed, try replacing the new unopened electrode sheet (rule out the possibility of electrode plug damage). If the problem persists after replacement, it indicates that the host slot is faulty. Contact after-sales service for repair.

Hello! AED electrodes are packaged in "sealed sterile packaging." Damage/opening can result in:

① The gel becomes ineffective due to moisture (affecting the conductive properties);

② The sterile state is destroyed (it may cause skin infection when attached), so damaged/opened electrodes are prohibited from use; please replace them with new unopened electrodes immediately (make sure they are within the validity period), and dispose of damaged electrodes as "medical waste" (put them in special garbage bags and collect them by medical institutions). At the same time, check the storage environment of the electrodes (they must be stored at 0-40℃ in a dry place and avoid direct sunlight).

Hello! When electrodes expire, their conductive gel loses its stickiness or conductivity, causing the AED to be unable to accurately analyze the heart rhythm. You need to:

① Immediately remove expired electrodes and replace them with new ones within their validity period (note that the type of electrodes must be compatible with the patient, e.g. adult/child electrodes cannot be mixed, and children need to use dedicated electrodes or electrode attenuators);

② Record the "opening date" of the new electrode sheet (it is recommended to use it immediately after opening, and it needs to be replaced even if it has not expired);

③ Expired electrodes should be handled as “medical waste” and should not be discarded at will.

Hello! App crashes may affect device status monitoring (such as battery level and self-test records). Please follow the steps below to troubleshoot:

① Confirm that the APP version is the latest (update the APP in the App Store, the old version may have compatibility issues);

② Close other background applications on your phone (to free up memory) and reopen the app;

③ If the app still crashes, try uninstalling the app and reinstalling it (note to back up the device binding information in advance to avoid rebinding failure);

④ If the problem persists after installation, it may be that the phone system is incompatible with the APP (for example, the phone system version is too low). You can try another phone and contact the APP customer service to report the problem (usually the contact information can be found in the APP "My - Help Center").

Hello! App Bluetooth connection failure may affect device data synchronization. Troubleshooting steps are as follows:

① Make sure the AED is turned on (some AEDs only turn on Bluetooth when the device is turned on) and that the Bluetooth is not occupied by other devices;

② Check whether the Bluetooth of your mobile phone is turned on. Turn it off and then back on. Search again in the "Device Connection" interface of the APP or wait for 30 seconds (when searching, make sure the distance between the mobile phone and the AED is no more than 10 meters and there are no metal obstacles blocking the view).

③ If the device cannot be searched, try restarting the AED and the phone, clearing the phone's Bluetooth "paired devices" list (delete the old AED pairing record), and pairing again;

④ If the connection still fails, check whether the AED Bluetooth function is normal (some models can check the Bluetooth status through "Setting Mode"). If the AED Bluetooth is faulty, contact after-sales service.
