Replacing the Battery in
HMC-ES252/552 Memory Cards
The Battery replacement procedure for the
HMC-ES252/552 is basically the same as that
for the HMC-ES251/551. The shape of the
Battery holder, however, is different, so step 3,
below, is different.
1. If the Memory Card power indicator (M/C ON)
is lit, press the Memory Card power switch to
turn OFF the indicator. If the indicator is
already not lit, press the switch so that the
indicator is lit for at least 10 s and then press
the switch again to turn OFF the indicator.
2. After confirming that the Memory Card power
indicator is not lit, press Memory Card
ejection button and remove the Memory Card
from the CPU Unit.
Complete Battery replacement (steps 3 to 5,
below) within one minute. If more than one
minute elapses, memory may be lost.
3. Slide the lock knob on the battery holder to
the left to release the lock and remove the
holder from the Memory Card.

5. Insert the battery holder into the Memory

all the way to the back, press in on the
battery holder so that it does not come out,
and slide the lock knob to the right to lock the
battery holder in place. Be sure that the
battery holder cannot be pulled output after
completing this step.
6. Insert the Memory Card into the CPU Unit.
