Sony CFD-470 - Manual (Page 8)

Power Sources
Two separate power sources are needed to operate this unit: one for the unit itself and one for the clock/timer/memory.
You can use the unit either with house current, or batteries. In either case, be sure to insert batteries for the
clock/timer/memory.
Notes
• The unit cannot be operated on the internal batteries when the AC
power cord is connected to the unit.
• For critical recordings or disc playing, operating the unit on house
current is recommended.
Battery replacement
Batteries for the operation of the radio cassette-corder:
When the batteries become weak, the OPR/BATT indicator
will become faint. In this case, replace all the batteries with
new ones.
Batteries for clock/timer/memory:
When the batteries become weak, the indication in the dis­
play window becomes faint. Replace the batteries with new
ones and then adjust the clock to the current time, reset the
timer setting, if necessary.
Note
When you replace the batteries for clock/timer/memory, be sure to
connect the AC power cord to the unit and to the wall outlet and turn
the power on before you remove the batteries.
