Dimmer Switch
The Dimmer switch located on the left side of your clock radio will allow you
to adjust the intensity of the clock display to suit room brightness.
Backup battery
As with all batteries, eventually the built in lithium battery will need to be
replaced. A number of factors, such as the length of time between the date your
clock radio was manufactured and the date you plugged it in for the first time,
determine the amount of time before replacement. During this initial storage
period the lithium backup battery is supplying power to your clock radios
computer memory. Once you connect your clock radio to the household AC
mains supply the battery no longer supplies power to your clock radio. A fresh
backup battery can supply power to your clock radio’s computer memory for 2
years even if it is never connected to a mains supply. If your clock radio was
connected to the AC mains supply within a few months after it was manufactured
and you experience only short interruptions to the mains supply, your battery
may last for up to 2-3 years or even longer.
When the power drops below a certain level the Low battery indicator will
light. When you see this indicator you should change the battery as soon as it
is convenient to do so.
