Setting the Rod Antenna
The radio is supplied with a fitted rod antenna (6). For FM
radio operation, point the rod antenna in the direction that
enables the best reception.
If the reception is insufficient, position the radio at a differ-
ent location that enables better reception.
Note: When operating the radio in the direct vicinity of ra-
dio-communication equipment or radio transceivers, or
other electronic equipment, the radio reception can be sub-
ject to interference.
Connecting External Audio Sources via AUX
Remove the protective cap of the connector compart-
ment (16) and insert the 3.5‑mm connector of the AUX
cable (26) into the AUX IN socket (25). Connect the AUX

To play back the AUX audio source, press the source but-
ton (7) until AUX appears on the audio source indicator (b).
After removing the AUX cable connector, reattach the pro-
tective cap of the connector compartment (16) to protect

Playback with True Wireless Stereo (with Bluetooth®
audio source)
If an audio source is played back via Bluetooth®, the true
wireless stereo (TWS) function can be activated. Two radios
(either GPB 18V‑2 C or GPB 18V‑2 SC) can be used as right-
hand and left-hand speakers for the same playback.
Activating the true wireless stereo function:
– One of the two radios must already be connected to the
audio source via Bluetooth®.

the menu <TWS> → <TWSR> (GPB 18V‑2 C) or
<TWS> → <TWS Right> (GPB 18V‑2 SC).
– Selecting the radio as the left-hand speaker: Select from
the menu <TWS> → <TWSL> (GPB 18V‑2 C) or
<TWS> → <TWS Left> (GPB 18V‑2 SC).
– Switch on the operating mode Bluetooth® on the second
radio as well.
– Select the other speaker from the menu on the second ra-
dio.
