What to do if WatchGas PDM show a Pump Blocked error?
If you encounter a 'Pump Blocked' error with your WatchGas Gas Detectors, ensure that there are no obstructions in the hoses and filters of the detector and PDM Mono Dock. Also, verify that the gas bottle is not empty or connected improperly.
What to do if WatchGas PDM show a communication error?
If you're experiencing a communication error with WatchGas Gas Detectors, make sure the IR communication window is clean and free of obstructions.
What to do if WatchGas Gas Detectors show 'No SD Card found' error?
If your WatchGas Gas Detectors display a 'No SD Card found' error, check the SD card and ensure the Lock function is not enabled.
How to fix WatchGas Gas Detectors Dock Led that won’t turn on?
If the Dock LED on your WatchGas Gas Detectors won’t turn on, be sure there is a power connection or place 6 x 1,5 V AA batteries in the battery pack.
