Wireless Computing RF-250 Operating Instructions

SETUP

1. Lay wrist rest and keyboard on a flat surface.

2. Position keyboard so wrist rest tabs are aligned under
matching slots in keyboard’s leading edge.

3. With both thumbs, gently press down on the left and
right sides of the keyboard until tabs click into place.

4. Turn keyboard/wrist rest over.

5. Free touchpad cable and plug it into the PS/2 jack
under the keyboard.

6. You can instead use your own PS/2 mouse with the
RF-250. Unplug the touchpad, then plug your mouse
into the PS/2 jack. Clip any extra mouse cable into the
guides on the keyboard underside. Note: Using a PS/2
mouse reduces battery life.

7. Remove the battery door on the underside of the key­board.

8. Insert two AA alkaline batteries (included) into the bat­tery compartment. The batteries face in opposite
directions. The directions of the batteries are marked.

9. Replace the battery door.

10. Plug the receiver into a USB port on your computer.
Do not place receiver on or in a metal cabinet, or near
other equipment and strong EMI sources.

SELECT ADDRESS TO ENABLE ENCRYPTION

When delivered, your RF-250 operates on address zero. You
may leave it on address zero, but while on address zero,
keystrokes are not encrypted and your computer may
receive and respond to signals from other Wireless
Computing products.

1. Press and release the black button on the underside of
the receiver. The LED on top of the receiver begins
blinking.

2. While the LED on the receiver blinks, press-and­release the Addr key. This sets the keyboard and
receiver to one of 65,000 random addresses and
enables encryption.

3. If you have a Wireless Computing mouse or remote
control and wish to use it together with this keyboard,
select this same address for the additional device(s).
Refer to the mouse or remote control instructions for
the button(s) to press. Each time you select an
address, the receiver LED blinks for 30 seconds, allow­ing you to address an additional keyboard, mouse or
remote control.

USING A MACINTOSH

To put the keyboard into Macintosh mode, press the Left­GUI, Left-Alt, Right-Alt, and Right-GUI keys together at the
same time.

Next, detach the WIN (2), Alt (2), Print Screen, Scroll Lock
and Pause/Break keycaps. Replace them with Option/Alt,
Cmd, F13, F14 and F15 keycaps (included). See the dia­gram on page 2 of these instructions.

OPERATION

The RF-250 Wireless Keyboard is designed to operate reli­ably at distances of 100 feet (30 meters). Operating range
varies depending on positioning of the receiver and key­board, nearby sources of interference and other environ­mental factors.

Pressing a key or sliding your fingertip on the touchpad
makes the green "sending" LED blink on the keyboard and
the receiver LED blink green.

The RF-250 will sleep a PS/2 mouse after 30 minutes of
inactivity to save battery power. To wake up the mouse,
press any key. Note: Using a PS/2 mouse reduces battery
life.

When the "low battery" LED turns on, replace the batteries
as soon as possible.
