Zingui

5 - Batteries
The Zingui has an internal Li-ion battery. A new and fully charged battery offers
about 6 hours of continuous use. This is with a display continuously turned on, a
backlight intensity of 50% (indoor use) and continuously playing sound.
Depending on the user and the power management settings this can be
sufficient to use the Zingui a day without charging. Especially when the user is
able to access the on/off switch to make use of the standby mode.
In case the standard battery would not be sufficient the Zingui can be equipped
with a double capacity battery.
The power adapter of the Zingui can charge the internal battery. When the
Zingui is not active, charging the standard battery will take about 90 minutes (or
3 hours for the double capacity battery). You can use the Zingui while it is
charged. In that case it will take longer to fully charge the battery.
The power adapter can stay connected to the Zingui when the battery is fully
charged. It is better though for the environment to disconnect the power adapter
when the battery is fully charged.
Do not use another power adapter than the one that is delivered with the Zingui.
Using another adapter could damage the internal circuits or the battery.
5.1 Replacing the battery
The internal battery is located behind the battery lid. Two special screws are
holding the battery lid in position. Only open the battery lid unless it is
necessary. Do not use a common screwdriver; you need a specific tool to do this
(Torx 6+).
First make sure that the Zingui is switched off (press and hold the on/off switch
for 4 seconds) and that the Zingui is not powered by the power adapter.
Put the Zingui with its display side on a clean table (preferably with some soft
tissue in between) so that the display cannot be scratched.
Unscrew the two screws with a Torx 6+ tool and turn the battery lid from its
screw holes towards you. You should not have to use force to do this. The
battery is visible now.
Take the battery out of its compartment and replace it with the new battery.
Control the position of the battery and slide the battery in the battery
compartment towards the battery connector. You should feel a little resistance
when the battery slides into the battery connector. But you should not use much
force to make the connection. If that would be the case, double check to make
sure that the position of the battery is correct.
If you are replacing the standard battery with the double capacity battery (or vice
versa) make sure that you are using the corresponding battery lid. (The battery
lid for the double capacity battery does not have fixation parts in the middle of
the lid.)
Screw the battery lid back on the Zingui housing.
Do not throw away the battery that has been replaced but use the proper waste
regulations of your state or region. You can always send the used battery back
to your local Jabbla representative.
5.2 Power management
The Zingui uses different ways to minimize power consumption in favour of its
battery life.
The Zingui has a light sensor to automatically adjust the backlight intensity in
function of the environmental light. When used indoor for instance the backlight
can have a lower intensity without really changing the visibility. Less power is
consumed in that case and battery life will increase. You can switch off the
automatic backlight adjustment and set it on a constant value.
For more
information about backlight adjustments see “Brightness” on page 20.
Be aware that more power is consumed when the backlight intensity is set
higher, resulting in a shorter battery life.
A second way to increase battery life is the use of the automatic turn off of the
display and backlight when the Zingui is not used for a specific period of time.
The display will turn on instantly when it is touched again or when an external
switch is activated.
