FCC GUIDELINES
This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment
generates, uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions may cause
harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
-Reorient or relocate the receiving antenna
-Increase the separation between the equipment and receiver
-Connect the equipment into an outlet on a circuit different from that
to which the receiver is connected.
-Consult the dealer or an experienced radio/TV technician for help.
FCC Caution: Any changes or modifications not expressly approved by the party
responsible for compliance could void the user's authority to operate this equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the
following two conditions: (1) This device may not cause harmful interference, and (2) this
device must accept any interference received, including interference that may cause
undesired operation.

2. Description:
The Topseed RF Keyboard is a FSK (Frequency Shift Key) Transmitter for the
frequency band 902-928 MHz. The RF Keyboard offers a full-integrated PLL synthesizer and
a high efficiency power amplifier to drive a loop antenna; A special circuit design and a unique
power amplifier design are used to save current consumption and to save battery live.
This keyboard specification applies 88/89 key membrane keyboard that is fully compatible
with IBM PC AT system. FSK-550 series keyboard are silent -touch and spill-resistant.
For the Receiver Modular use with USB 1.1 compliant can be easily actuated without
affecting the position of the Keyboard.
Note that the Channel button (Red button) on the receiver should flash any time the Cordless
device is moved or a button is pressed. Then, it will remember your product ID and Channel
ID
The Radio Frequency designed in this Version of RF Keyboard is FSK 912MHz and can be
use in a range to about 10 Meter from the Receiver at any directions. The Keyboard can
operate for 10-12 months with two AA Alkaline batteries.
