Positioning the
Receiver
The receiver is multi-positional. It can stand up or lay flat on either side. If you are placing it
on a table or desktop. It is best to stand the receiver up to minimize any disruption of the
signal by the table or desktop.
When you are mounting or positioning the receiver be careful not to block the lens from line-
of-sight contact with the Keyboard. The Keyboard is powerful enough to bounce the infrared
(IR) signal off the walls, but obstructions close to the receiver may interfere.
Keyboard
Range
Indoors, in the absence of IR light sources, operating ranges will be up to 50 feet (15.2
meters), and, under ideal conditions, beyond. Naturally, individual results will vary depending
on how you use your keyboard.
Battery Life
Both the keyboard and mouse pad use what is known as “sleep mode”. When nothing is
being typed on the keyboard, the IR LED’s and the keyboard processor go to “sleep,”
consuming a mere fraction of their normal power requirements, while waiting for the next key
press.
Under normal usage, several pages per day, battery life of up to a year will be typical. Again,
your results will depend on how you use your keyboard.
When it finally comes time for battery replacement, you will begin to notice a reduction in
range, typified by lost keys at longer distances. Please use only alkaline batteries only.
