SmartPower®: Please feed the Meaty Monster (part 1)

Blue LED
Some of you have asked our tech support about the how to fully-charge the micro iDSD from the get go.

Short Answer:
The micro iDSD manual covers the lion’s share of charging eventualities. All that it requires is connection to a suitable USB power source and left alone until the BLUE led is extinguished (length depends upon battery %). Thereafter, it is ready to play music.

If however for any reason the micro iDSD never reaches this state, the battery is likely to be operating on an empty tank – hence the various LED states reported.

Long Answer:
Please refer to the tables in this User Manual Addendum. If you have any queries, please open a support ticket: http://support.ifi-audio.com/

Blinking Red Unit has gone into “battery critical” shutdown. No power source suitable to recharge is attached (e.g. an iPhone is not “suitable” and so no current will be drawn from the iPhone). All functions are off, current draw is a few mA from the battery, LED will blink until unit is turned off or the battery is exhausted, appx. 48 hours in this state. Until the battery is recharged by about 15% the unit will remain “locked in shutdown”. Turn unit off, attach a charger, make sure charging commences and leave unit to charge until blue charge indication turns off. Depending on charger and discharge state this may be between 8 and 24 hours. It is possible to resume use after partial charge, but it is best to restore the battery to full. At this point the unit attempts to protect the battery from a deep discharge that would reduce lifespan. If resolved in good time, there is no negative impact.
Blinking Red/Blue Unit has gone into “battery critical” shutdown. As part of the shutdown the iDSD micro tests if a power source suitable to recharge is attached (e.g. an iPhone is not “suitable” and so no current will be drawn from the iPhone). Such a power source was detected and the iDSD micro is in full shutdown but recharges from the USB Power Port. Turn unit off (at which point the LED will indicate charging by turning a steady blue) and leave the unit to charge until blue charge indication turns off. Depending on charger and discharge state this may be between 8 and 24 hours. At this point the unit attempts to protect the battery from a deep discharge that would reduce lifespan. If resolved in good time, there is no negative impact.
Blinking Green (very fast) The battery’s own protection circuitry has disconnected the battery to prevent deep discharge that may cause damage to the battery. The iDSD micro is inoperable until the battery is restored to healthy status. Turn unit off (at which point the LED will blink blue very fast). At this point the iDSD micro will charge the battery under USB charging standard “flat battery provision” at very reduced rate to avoid damage. Afterwards the battery can be charged normally again (normally will be the case within <30 min) the unit will return to normal charging with a steady blue LED indication and leave the unit to charge until blue charge indication turns off. Depending on charger and discharge state this may be between 8 and 24 hours. In rare cases (actually so far only theoretical, we have not been able to provoke this in practice) the battery may be depleted so much that after the expiry of the 30 minutes for “flat battery provision” the battery can still not be charged normally. In this case the unit will shut off completely. Then the iDSD micro must be un-plugged/re-plugged from the USB port to restart another 30 minutes “Flat Battery” cycle. At this point the unit attempts to protect the battery from damage. In this rare instance, the impact if any is likely minimal, but repeated cases of the battery protection circuitry engaging may impair battery life.

There is no other risk as the protection circuitry prevents battery states that may result in damage.

Worst case scenario, have your micro iDSD serviced by an authorised repair centre – to exchange the battery.

Blue (goes off after few seconds) 1) Battery is full, no need to charge.

2) Not enough current to charge the battery, cannot charge.

1) Great!

2) Please try different charger, port cable etc.

2) Try a different charger and if the blue LED still goes off, then it should be fully-charged.
