Errors & omissions excepted
In implausible case the keyboard does not work even after new-synchronisation, you have the following
options to solve this problem:
Repeat the procedure of synchronisation as described under 3.4. Sometimes it is necessary to repeat this
•
routine several times, until the right radio channel is found.
In case your USB receiver is attached to an USB hub, you should install it directly on the USB connector
•
of your notebook or desktop.
During the procedure of synchronisation the keyboard should be located close to the USB receiver to make
•
sure, that the immediate environment has no infl uence on the radio transmission (for instance reduction/
interferences due to metal cases, other sources of interferences etc.).
Ensure that you use only batteries with full loading capacity. In
•
case of doubt change the old batteries before next synchroni-
sation against new ones as a precaution. Low battery capacity
is signalised by glowing of the right blue LED.
3.5. Trouble shooting
If the keyboard suddenly has no function at all after it has been operated for a while, please try to pair it again.
If it works, then it may be interfered by the pairing information from a similar keyboard. If it still does not work,
please check the batteries or move the keyboard to a different location to test.
4. How to use the keyboard
After successful launch enjoy now during the operation a free and independent choice of location up to ap-
•
prox. 7 m distance to the PC. More or less range can be caused, like mentioned above, by metallic dividing
walls, other computer cases, monitors, ZIP drives, loudspeakers, switching power supplies etc., but also
by different loading capacity of the batteries.
4.1 Optical trackball
As a mouse alternative the keyboard is equipped with a optical trackball inclusive two mouse function keys
allowing comfortable and ergonomic handling of the PC, for instance from a sofa. Thereby the handling of the
trackball is as simple as brilliant.
Move with the right thumb softly the ball of the trackball to
•
move the
cursor on the screen.
With the mouse function keys, click and double click functions
•
can be
explained, absolutely identically as with a mouse.
In order to „drag“, to draw or to mark, you must keep the left key
•
with
the left thumb pressed to carry out the function then with the right
thumb on the trackball.
In order to increase or decrease the speed of the mouse-pointer
•
mo-
vements, change the settings of the mouse options in your system
control under Windows*.
Using notebooks with already integrated touchpad you have to
•
de-
activate these intern control devices in case of error messages or
malfunctions*.
Should the precision of the cursor decrease after several months of usage, please check the installed batte-
ries for their state. In the case of doubt exchange them for new.
