Nokia MD-4 User Manual

The speakers are powered by four AAA batteries. Alkaline batteries are recommended. To 
install the batteries in pairs, slide the battery cover on the outer side of each speaker 
toward the hinged end of the speakers, place the batteries as indicated in the battery 
compartment, and close the battery cover by sliding it to the opposite direction. During 
long periods where the speakers are not used, remove the batteries to prevent damage 
from battery leakage.

You can use the speakers folded together or unfolded (for example, to form a V shape). 
The speakers are convenient to carry when folded. The speakers can be unfolded up to 
approximately 180 degrees. Do not try to force the speakers open more.

To connect the speakers to the phone or audio device, plug the speaker cable into the 
connector on the device. If the phone or audio device has a 
Pop-Port connector or a 2.5-mm connector, connect the AD-15 or AD-50 adapter 
(respectively) to the device. Then connect the speaker cable to the adapter.

To switch on the speakers, slide the power switch located inside the unfolded speakers 
toward the hinged end. The green indicator light turns on. To switch off, slide the power 
switch to the opposite direction, or fold the speakers closed. The indicator light turns off.

To set the volume, use the volume controls on your audio device. If the sound level of 
the speakers becomes too low, change the batteries.

To carry the speakers, fold them and place them in the supplied pouch.

Your device is a product of superior design and craftsmanship and should be treated with 
care. The suggestions below will help you protect your warranty coverage.
