BlueSnap AAA LEDs
The RED LED just shows that power is on, and slow charging the batteries.
When using charger, batteries used should be at least 800 mAh type NiMH, and must be matched (i.e. both same type and rating).
Only use Alkaline batteries when external power NOT attached.
This can be left on, there should be no risk of overcharge as the charge is about 100ma, about 10% of capacity depending on the battery.
The BLUE LED only comes on when the unit is awake, and will blink a few times on power on to show you the device is ON. Then it should
stay off, until the battery sensor decides the batteries are low. BLUE LED should BLINK when batteries are low.
Low battery setting is programmable and currently set for NiMH batteries with 800 mAh or more to give at least a few minutes of run time.
Value is currently set to 1900mV. (1.2V is nominal voltage for NiMH).
BLUE LED should come on SOLID when the charger is detected. It should turn OFF
