BATTERY AND CHARGER FOR THE EEGO AMPLIFIER
The
eego
amplifier comes with a built-in rechargeable Li-Ion battery. The battery provides several
hours of operation time. The exact value may vary depending on the operation mode of the amplifier
(more current is drawn from the battery in impedance measurement mode), operating temperature
and aging effects of the battery similar to other battery-driven devices. The charging process takes
usually less than 2 hours to complete.
The LED light-pipes at the side edges of the
eego
amplifier communicate POWER and DATA status as
well as possible hardware problems. The two multi-color LED indicators at each side operate
symmetrically.
The following table gives a description of the battery status as shown with the
POWER
LED.
POWER
LED color*)
Battery
Status
Description
Red
Low
Battery is in the low charging state. You should stop the recording and
recharge the amplifier immediately.
Yellow
Medium
Battery is in medium state. At least 1 hour of operation time remains but
the device should be recharged now. Do not start a new recording.
Green
High
Battery charging state is high.
Table 2-1 Display of battery status as shown with the POWER LEDs.
The POWER indicator light is
breathing
, i.e. brightness of the LEDs is oscillating slowly, when the
battery is charged (supposing that the power supply is attached). Please remember that for best
signal quality the power supply should not be attached while recording with the amplifier.
In case you experience drastically reduced battery operation times of the amplifier, please contact
Support for options to check the device and possibly to exchange the battery.
WARNING: Do not attempt to open the amplifier or battery compartment yourself!
The battery charger for
eego
amplifier comes with a power cord and plug fit for a particular region. A
green LED indicator in the power supply shows whether the device is turned on.
*) The LED indicators are not active when the amplifier is turned off. Nevertheless, the device will
be charged when the power supply is connected. You can check the charging status by turning on
the device.
