Alarm Clocks

If the preset DAB/FM station signal is not strong enough the alarm will go off in buzzer mode instead. Make sure the signal is strong enough, by checking that the station plays without static or distortion (FM).

You must first set a radio preset by tuning to a radio station and holding down the 1, 2, or 3 button to save it. After this, the preset will be an option when setting up a new alarm.

When setting up the alarm, the options will be displayed in the following order:
​​​​​​1. Set Alarm Hour.
2. Set Alarm Minute.
3. Set Recurrence - Weekday/Once.
4. Set Ringtone - 4 built-in alarm tones or radio preset 1/2/3 (see information above).
5. Set Light - On/Off.

If the light is set to 'On' when the alarm is set up, once it goes off it will gradually increase in brightness over 10 seconds.

On the bottom panel, rotate the battery cover into the unlocked position and remove the cover. Press the battery clip visible on the back side of the battery compartment to allow the existing battery to come out. Then insert the new battery in the slot with the + side visible (facing up), and install the battery cover again. Rotate the battery cover to lock it into place.

On backup battery power, please wait 50 seconds for the alarm to turn off automatically.

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.

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.

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.

After the wake-up process is finished, and the radio alarm has been turned off by pressing the alarm button, it is necessary to press the radio button to keep the radio playing.
