The display is not permanently illuminated at night, but has a backlight that is activated at the touch of a button. This means it is not permanently dazzling and is ideal for the bedside table, as the light is only switched on when required. This makes it easy to read the time even in the dark without the display being distractingly bright. The backlight can be controlled via a touch button (snooze/light).
The BC08 and BC09 alarm clocks from Braun both have a crescendo alarm function in which the alarm becomes progressively louder. This function is explicitly mentioned in the official product descriptions and features of both models.
There is no indication that there are older versions of these models without the crescendo function. The current and newer versions of the BC08 and BC09 are equipped with this function.
I have been using this alarm clock for 2 1/2 years now, without changing the battery. Never had any problems. Sounds like a defective model (warranty case).
With the current version of the Braun radio-controlled alarm clock BC09W-DCF, the automatic time changeover works without any problems. Here are the relevant details:
- The alarm clock receives the DCF radio signal from Frankfurt, Germany, which provides the most accurate clock in the world.
- The automatic time and date setting, including the changeover to summer and winter time, takes place without manual intervention.
- This means that the alarm clock displays the time and date to the second and automatically adjusts to changes in summer and winter time.
The display of the Braun BC09 does not specifically light up when the alarm goes off, but it has a backlight function that can be activated manually to see the display in the dark.
The BC09 is an evolution of the classic BNC009 digital clock, with enhanced features and functions in response to customer feedback and experience. The BC09 features a crescendo beeping alarm, snooze function and backlighting and an LCD display with 12 and 24 hour setting options, all of which enhance the functionality of this clock. A design that reflects Braun's principles of consistency, simplicity and clarity of design.
- Crescendo beeping alarm
- Touch snooze function
- Backlight function
- Negative LCD display with 12/24 hour display
Therefore, the BC09 is a newer model with improved features.
