How come my alarm clock does not reach my desired radio station, but my car reaches it with no problem?
I wanna get a radio station that is Detroit, Michigan, but I can't get it with my alarm clock and my car has no problem picking up the signal. What is the problem?
The antenna in your clock is inferior to that in your car, and the receiver is probably less sensitive too.
There's nothing you can easily do to improve matters.
In today's market, there are alarm clock brands featuring projection displays, high fidelity sounds, and iPod docking system on their packages. In shopping for an alarm clock, however, let us never forget the importance of some necessities despite the variety of sophisticated features. Among these necessities is the alarm clocks' battery backup.
Alarm clocks' battery backup is so necessary because all the features of the clock would deem futile without the power source. Furthermore, the main function of the clock is to wake you up on time through its alarm. Electricity supply failure can cause the alarm clock to reset at the middle of the night, making you oversleep as a result.
The battery backup is definitely essential to preserve the clock's circuitry running. So, in case there should be a power failure at night, the alarm will still sound to wake you up. The backup however is not sufficient enough to keep the display illuminated. But the fact that it prevents you from over sleeping the following morning is a great relief for your part.
A few decades back, the main problem with the first digital clocks was that when there was a power failure, the clock will reset itself after power was resumed. When there were power cuts during at night, the alarm clock will reset itself to 12:00:00.
The solution to this is the inclusion of battery backups with recent designs. With this backup, the battery would still maintain the power and prevent the clock from resetting by maintaining the availability of electrical charge.
With battery backups, there are two types used in most common alarm clocks in the market today. The first one is the type of clock using capacitors for storage of electricity just to keep the clock's settings, especially the alarm time, in the instance of an hour or so power supply failure. The problem with this type however is that the power stored may not let the alarm sound or illuminate the dial. It will only keep the clock run and avoid the resetting until the power supply is restored.
The second type of battery backup is the use of actual dry cell or battery. The battery will work like just the same as the capacitors but for longer periods of up to a few days. It can also let the clock's alarm sound like when in normal function with main electricity supply.
In conclusion, the alarm clocks' battery backup is truly important even with just a simple role in restoring the clock's functions. Now, you can avoid oversleeping while you expect your alarm to sound on time whether with or without power.
