To keep good time, this unit contains one CR2032 
battery inside of the unit as a backup power source.
The battery keeps the clock operating in the event of a 
power interruption.

When the battery becomes weak, “

” appears in the 

display.
If a power interruption occurs while the battery is 
weak, the current time will be initialized.
Replace the battery with a Sony CR2032 lithium 
battery. Use of another battery may cause a fire or 
explosion.

Note
If “AM 12:00” flashes in the display when the unit is 
connected to AC outlet for the first time, the battery 
may be weak. In this case, consult your Sony dealer.

Keep the AC plug connected to the AC 
outlet and pry out the battery holder at the 
bottom of the unit using a slender rod, such 
as a screwdriver. (See Fig.

Push the exhausted battery out from the 
bottom of the battery holder and insert a 
new battery with the
