About the backup 
battery
To keep good time, as backup power source, this unit 
has one CR2032 battery inside of the unit in addition 
to the house current (The battery is supplied with the 
unit for Australian model.). 
The battery keeps the clock and the alarm operating in 
the event of a power interruption.
Knowing when to replace 
the battery
When the battery becomes weak, “E” indicator 
appears in the display. 
In the event of a power interruption when the battery 
is weak, current time and alarm functions will be 
initialized.
Replace the battery with a Sony CR2032 lithium 
battery. Use of another battery may present a risk of 
fire or explosion.
Note for customers in the UK
The clock is preset at the factory, and its memory is 
powered by the preinstalled Sony CR2032 battery. 
If the “AM 12:00” flashes on the display when the 
unit is connected to AC outlet for the first time, the 
battery may be weak. In this case, consult a Sony 
dealer. The preinstalled CR2032 battery is considered 
part of the product, and is covered by the warranty. 
You are required to show “Note for customers in the 
UK” (in this instruction) to a Sony dealer in order to 
validate the warranty for this product.
