JBL Horizon

At the bottom of your Horizon alarm clock, you will see a little cap where the backup-battery resides. Turn the cover lid left to open it, and on the back of the cover lid, you will see the serial number.

By pressing and holding the Bluetooth and the Volume PLUS buttons at the same time. The software version is shown in the display.

Yes, if a telephone is connected via Bluetooth to Horizon, this is possible. When adjusting the wake-up timer, there will be an option to select various wake-up tones, or Bluetooth sound. Select Bluetooth as source, while the telephone is playing the music stored locally, or streaming what you want as wake-up music. When the wake-up adjustment is finished, music will be playing over Bluetooth through the Horizon. Press Pause on the source telephone, or press the round selector button (between the two arrow-buttons) on the Horizon to pause the music. Now the system is ready to wake you up with Bluetooth music. When wake-up time arrives, Horizon sends a Play command to the telephone, and music plays via Bluetooth. You can use music that is stored in the phone, use Spotify or play from the cloud. This has been tested with both iPhone 6 and Samsung S6, and should work flawlessly.

Horizon's alarm sounds for 3 minutes, then it shuts off, or rather it goes into snooze, for 9 minutes. Then it sounds the alarm again for 3 minutes, followed by snooze for another 9 minutes. After this final snooze period, it starts playing, and keeps on playing until it is manually shut off. The light shuts off with the audio.

The lights cannot be adjusted by user. The digital front panel display has automatic light intensity adjustment, which follows the level of light in the room.

The owner's manual can be a bit difficult to understand. Here is what to do to program a preset station that has not already been saved in any preset: 1 Turn on the radio by clicking the FM button. 2 Find the station you want to save by doing what is shown under pt. 8 B or C, either clicking or pressing/holding for more than 2 seconds the left/right arrow buttons. 3 Press and hold the FM button for more than 2 seconds. Now the preset number appears blinking. 4 Click on the left/right arrow buttons to skip through the preset positions. 5 When you have located the desired memory preset position, such as Preset 4, confirm by clicking the FM button. Now the desired FM station is saved in memory preset 4. If you have already saved an FM station in a preset memory position, and want to have a new station placed there instead, here is what to do: 1 Turn on the radio by clicking the FM button. 2 Jump to the preset station you want to change with the round central button. Each click advances to the next preset. 3 When you are on the preset you want to change, e.g. preset 4, press and hold the FM button for more than 2 seconds. 4 The FM symbol and the frequency will now blink. 5 Before they stop blinking, click, or press and hold one of the arrow buttons to go through the FM frequencies step by step, or perform station search. 6 When you have found the new station you want to save in preset 4, click the round central button. 7 Now the new station is saved in preset 4.
