Q/A

Q: Why battery not included in package, It's not worth money.

A: Actually, we are not think about reducing our cost for not including the batteries, the main reason is we need transport our products to AMAZON warehouse from our country, as we all know, international transport of battery is inconvenience. I n addition, the AA battery is cheap and you can get it anywhere very convenient, we suggest you to purchase the rechargeable type battery for saving money and protect our environment.

Please be noted:

>> Read the user manual before use.

>> Do calibration before detection, turn on the detector, 120 seconds countdown starts for pre-heating, when countdown finished, put it in fresh air for at least 8 minutes, then keep pressing the switch button till the green light twinkling, calibration is finished and ready for use. Normally, we do not need calibrate it for every time use, however, it is better to calibrate it before using each time for accurate result.

>> If the item is in low battery, the data may be inaccurate, please make sure enough power in battery.
