4.5. Charging

Please charge the detector when it shows low battery or the
detector can't be turned on due to low battery. Before charging,
please turn off the detector. After you connect the charger correctly
between the detector and AC power source, the detector will be
turned on automatically. When the battery mark on the screen is
full and doesn't change any more, it means the charging is
completed. Please pull off the charger.
Warning: During charging status, the detector can't detect the gas
leakage. Please do not try to charge it at testing places to avoid
fire or explosion. Please do not charge it when the detector is
working to avoid potential damage.
Note: Make sure full charge for at least once within 3 months
since production date.
