Hi :)

Please tell me how many Hours it takes to make the First charge of the battery in the EMF-390 after the purchase, before using the device ?

Will it need to be charged for 16 hours straight, like GP Ni-MH batteries ?

Thank you :) for training ...

0.0006 - 0.0128 mcW/cm2 = 0.006 - 0.128 mW/m2 = 48 mV/m - 220 mV/m :

Fatigue, depressive tendency, sleeping disorders, concentration difficulties, cardio- vascular problems reported with exposure to GSM 900/1800 MHz cell phone signal at base station level exposures.

Hi Green Peace, probably around few hours/minutes. It usually comes almost fully charged but occasionally it comes half the charge.

Thank you :) EmfDev !

The Meter has already received a 100 % battery charge, more than 4 Volts of charge.

The Meter works perfectly and shows detailed information about the surrounding EMF levels

0.0006 - 0.0128 mcW/cm2 = 0.006 - 0.128 mW/m2 = 48 mV/m - 220 mV/m :

Fatigue, depressive tendency, sleeping disorders, concentration difficulties, cardio- vascular problems reported with exposure to GSM 900/1800 MHz cell phone signal at base station level exposures.

Hi, received my EMC-390 yesterday. Is still charging since then! (24h as of now) Meaning: It shows" "Charging... 100%" from the start. The documentation states that the charging is complted when the battery icon stops flashing. It is still flashing. Reading this topic charging can be slow but it is to be expected that new models are mostly almost fully charged. Any suggestions?

Hi kbfifi, this may be because the backlight level is too high. I think 100% should be around the 4.1V so it is ok remove it from charging.

Hi EmfDev, thanks for thinking with me! I've used the meter for some days now. Works just fine. Just recharged it back to 100% in the hope it was an initial behaviour. But it still keeps showing animating battery icon. So I guess it may be because of an FW update or the manual not being accurate. I consider the 100% info as leading and ignore the the animating icon.
