DIMMER Control
The display dimmer control was set to the HI (High) position at the
factory.
If you find the display to be too bright for sleeping, slide the DIMMER
switch to the LO (Low) position.
Changing The Lithium Battery
Like 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 the 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 battery is supplying
power to the SmartSet® computer memory. Once you plug the radio
in, your household outlet supplies the power, and the battery is not
being used.
A fresh lithium battery can supply power to the SmartSet® computer
for at least three years even if it is never connected to an AC power
supply. If your radio was connected to your AC supply within a few
months after it was manufactured, and you experience only the
normal, nuisance-type, short duration power interruptions, your
battery may last for up to five years or even longer.
