Getting ready to use the R-4

battery runs down, the battery icon will change as follows.

When the battery reaches Level 0, the message shown will appear.
Replace the batteries as soon as possible.
If you continue using the R-4 when the batteries have run low, the
screen shown here will appear, and then the power will
automatically turn off shortly thereafter.
