changes are not permanent until the Accept Changes soft key is touched.

5. When the date and time are correct, touch the Accept Changes soft key. This

changes the time to the new values and returns to the previous application.

CAUTION.

The backup battery used to retain stored data has an operating life of

greater than 10 years when operating between 0

and 50

C. If operating out of that

range for extended periods of time, the battery life can be reduced or stored data

can be lost.

The nonvolatile memory of the AM700 is held by an internal backup battery. Stored

data will be retained for the life of the battery. A fresh battery installed at the factory

has a life of greater than 10 years when operated and stored at an ambient

temperature between 0

and 50

C. Battery life can be reduced if the AM700 is

stored for an extended time above 50

C, and retained data can be lost if the AM700

is stored for extended periods below 0
