RCU contains an embedded micro gyro for motion sensing and in-air control of floating
cursor. This RCU features an IR code database and IR learning capabilities to
universally control standard home theater TVs.
The RCU is also equipped with a 2.4 GHz RF transceiver to send cursor movement
information and other commands to the PC via a built in transceiver. The radio
frequency (RF) transceiver delivers a range of up to 100 feet with no line-of-sight
requirement. The 800 possible channels of the RF transceiver provide high resistance to
interference from other radio devices.
Battery Installation and Information
The Media Center RCU requires four AAA Alkaline batteries. To install the batteries:
1. Remove the battery compartment cover.
2. Insert the batteries, matching the batteries to the (+) and (-) marks inside
the battery compartment.
3. Replace the battery compartment cover and snap it into place.
Note: Reprogramming may be required after batteries are replaced.
Battery Saver
The RCU saves battery power by automatically going into a low-power state if no button
is pressed after a few seconds. See the Gyro section for gyro battery saver mode.
Gyro Operation
The RCU provides in-air control of the PC’s cursor via patented gyroscopic motion-
sensing technology. This means mouse-like cursor control, from anywhere in the room,
without the need of a flat surface. There is no line-of-sight requirement so you don’t
have to point the RCU at the PC you are controlling. Remember the following things
when using the in-air cursor control feature of the RCU:
• Use your thumb to press the gyro and mouse buttons. [add picture of hand holding
the RCU]
• Click the center button to activate the gyro motion-sensing control. Single click
and hold to move the cursor and release it to “park” the cursor where you want it.
Double click the center button and release it for continuous cursor movement
similar to a standard mouse.
• The right and left buttons function like standard mouse right-click and left-click
buttons.
• Move the cursor by flexing your wrist, not your arm or body, much as you would
with a flashlight; side to side and up and down. Placing your arm on an armrest
or on your lap will make this motion more comfortable.
• The RF Transmit LED indicates when gyro motion or other information is being
sent independent of which mode is selected on the RCU.
