to ensure your own safety and to prevent possible damage to your OB–4: do not expose OB–4 to rain or moisture. clean with a dry cloth. place OB–4 on a flat and level surface to prevent it from falling.
protect your hearing. be careful when turning up the volume and do not listen too close to the speaker on high volume for a long time.
to prevent malfunction or damage, turn off the power to all devices before connecting OB–4 with other units. OB–4 has a very low idle power consumption. but, if you are not going to use it for a longer period of time we recommend unplugging.

the internal battery already has some charge out of the box, but we recommend 1 to 2 hours of charging the first time you use your OB–4.

OB–4 is designed to sound fantastic anywhere.
for the best listening experience in a room; place OB–4 on a table, windowsill or shelf.
if you want to make the bass response richer, place the back panel about 10 cm from a wall or window.
an alternative way of placing OB–4 is tilted, leaning on its handle. this way the top panel is easily accessible and visible.

once you've found a good position, you could find a place to hand the antenna using the integrated hanger. usually the antenna works best if it is full extended away from OB–4.
for listening on the go, the curly section of the antenna fits into the handle. grab the rubber stoppers and stretch to fit.
