The instrument comes together with a universal EURO plug charger that may be powered
by voltages ranging from 110 to 240V @ 50 - 60 Hz. Should you use the charger in areas where
no socket compatible with the Euro plug is available, a proper adapter should be applied (one
should purchase an adapter as such separately).
When the battery is being charged, one can use the headphone amp. However, in circum-
stances as such the charging would take longer. It is recommended that the battery is charged
with the headphone amp turned off.
When, after the charger is plugged in, the yellow charging LED does not light up, nor does
the green LED become active, this may mean that your charger, charging cable, or charging
port has been damaged, or that the cable is plugged in improperly, or that the battery is
unplugged. In the worst-case scenario, the above symptoms may mean that the headphone
amp has been damaged. In a situation as such, try unplugging and plugging in the charging
cable. Alternatively, you could also use another compatible charger.
Note:
It is not recommended to plug Cali into the PC USB port, as most of these ports do not provide
current that has proper charging parameters for the battery applied.
Tip:
The internal battery may also be charged with the use of an external power-bank providing 5V/1A
charging power. To provide a full charge, at least 2500 mAh power bank is required. The power bank
could be used as an alternative charging unit in places where no mains access is available. It is also
possible to use another charger that has output parameters equivalent to the charger that comes
with the instrument (5V, 1A) and has been fitted with a micro USB plug.
Important!
The micro-USB port is used solely for charging the battery. It is not used as an audio output.
Headphone Amp – How long can I use it on a single charge?
When the battery is fully charged, with 32 Ohm stereo headphones being plugged in, you
can use the headphone amp for around 26 hours, with comfortable playing volume.
Note:
Do not leave the mini-switch in the top position - when the mini-switch is in this position, power is
supplied to the headphone amp. This may lead to a rapid discharge of the battery.
