5. Memory Preservation
DC,WT,DD
DC,WT,DD
This unit does not require memory preservation batteries.
GR,WT,PA,PT
A built-in memory power backup system preserves the contents of
GR,WT,PA,PT
memory during power failures and even when the power cord is unplugged.
GR,WT,PA,PT
The power cord must be plugged in order to charge the backup system.
GR,WT,PA,PT
The memory preservation period after the unit has been turned off varies
GR,WT,PA,PT
depending on climate and placement of the unit. On average, memory
GR,WT,PA,PT
contents are protected over a period of a few weeks after the time the unit
DC,DD
has been turned off.
DC,DD
This period is shorter when the unit is exposed to a very humid climate.

6.Setting the voltage selector

(Worldwide models only)
The Worldwide model has a voltage selector for compatibility with
power systems around the world. Before you plug in this model,
make sure that the voltage selector is set to the correct voltage for
your area. If it isn't, use a small screwdriver to set it as appropriate.
For example, if the voltage in your area is 120 volts (V), set the
selector to "120V. " And if it's between 220 and 230 volts (V), set it
to "220-230V."
