not detected

●

Be sure that you are using the wireless keyboard or wireless mouse within range of the transceiver,

approximately 10 meters (32 feet) for normal use, and within 30 cm (12 inches) during initial setup or for re-

synchronization.

●

Be sure that the mouse is not in Suspend mode, which occurs after 20 minutes of inactivity. Click the left mouse

button to reactivate the mouse.

●

Replace the batteries in the keyboard and/or mouse.

Speakers and sound

Symptom

unsatisfactory

Be sure that you connected the speakers to the audio-out (black) jack on the back of the computer. (Additional audio

jacks are used for multiple-channel speakers.) Detached nonpowered speakers (speakers without a separate power

source, such as batteries or a power cord) do not produce satisfactory sound. Replace the nonpowered speakers with

powered speakers.

No sound is produced

Type

control panel

in the taskbar search box, and then select Control Panel. Select System and Security.

Under Security and Maintenance, select Troubleshoot computer problems, and then select Troubleshoot

audio playback.

Be sure that you connected powered speakers and that they are turned on.

Turn off your computer, and then disconnect and reconnect the speakers. Be sure that the speakers are connected to

an audio jack, not a microphone or headphone jack.
