6.3 Preparing the DIGITRADIO 231 OD for operation

6.3.1 Connecting to the mains and charging the baery

When used for the first time, the DIGITRADIO 231 OD rechargeable baery must be fully charged. Observe the safety instructions for charging lithium-ion baeries. WARNING! Do not touch the mains plug with wet hands; electric shock hazard! CAUTION! Route the mains cable in such a way that nobody can trip over it. > Plug the power supply unit into a wall outlet. Then insert the DC plug of the power supply unit into the DC socket on the radio. > The DIGITRADIO 231 OD starts and runs an initial scan for stations in your area via DAB+. Ensure that the antenna is correctly aligned as per Section 6.3.2. > Once the station search has successfully completed, the first DAB station on the station list is played. The charging status is shown in the upper right corner of the display101

The baery will be charging when the DIGITRADIO 231 OD is in standby. The power supply unit can be stowed in the designated slot (19) on the back:102

6.3.1.1 Using an auxiliary baery

The DIGITRADIO 231 OD can be operated with auxiliary baeries (18 V) from well-known manufacturers (BOSCH, DeWALT, MAKITA). To do this, the appropriate adapter must first be installed in the DIGITRADIO 231 OD. A list of compatible baeries can be found in the chapter Technical Data. MAKITA DeWALT BOSCH > Open the baery compartment cover (17) on the centre rear of the device by pressing the locking tabs downwards. The baery compartment lid can then be flipped down and removed. > Plug the auxiliary baery onto the adapter plate (1) that corresponds to your baery manufacturer. Observe the safety instructions provided by the baery manufacturer.103

> Insert the adapter plate into the DIGITRADIO 231 OD as far as it will go (2). Fold up the two securing lugs (3) and hand-tighten the screws. As soon as an auxiliary baery (charged) is plugged in, power is supplied via the auxiliary baery. If the auxiliary baery is flat, power is supplied by the internal baery.104 The auxiliary baery cannot be charged in the DIGITRADIO 231 OD. To do this, remove the baery from the DIGITRADIO 231 OD and use the original charger from your baery manufacturer. If the DIGITRADIO 231 OD is operated with an 18 V auxiliary baery or the mains adapter, the boost mode is activated. With this the music power is 2 x 15 W. > Close the baery compartment cover again by first inserting it at the boom (4) and then snapping it into place at the top (5) :105

The number and quality of broadcast stations depends on the reception conditions at the location of the radio. Excellent reception can be achieved using the telescopic antenna (18). > Align the telescopic antenna (18) and extend it. The exact alignment of the telescopic antenna is oen important, in particular at the fringes of the DAB+ reception area. You can quickly find the location of the nearest transmission tower online by visiting “www.dabplus.de”. Start the first scan by a window facing in the direction of the broadcasting mast. Bad weather may cause the DAB+ reception to be restricted. Do not touch the telescopic antenna during station playback. This could reduce the reception and lead to sound dropouts.106

6.3.3 Using headphones

Hearing impairment! Do not listen to the radio at a high volume with headphones. Doing so can cause permanent hearing impairment. Turn down the radio volume to the lowest volume before using headphones. Only use headphones with a 3.5 mm jack plug. > Insert the headphone plug into the headphone jack (14) on the back of DIGITRADIO 231 OD. Sound is now played exclusively through the headphones; the speaker is muted. > If you want to use the speakers again, unplug the headphones from the headphone jack on the device.107
