The miniature lithium battery, Matsushita BR2325, which powers your watch
should last approximately 1.5 years. However, because the battery in your watch
is inserted at the factory, its actual life once in your possession may be less than
the specified period.
The seal pasted on the watch case back shows the date that the battery was in-
serted at the factory, and thus helps to determine when the battery should be
replaced. Be sure to replace the battery as soon as possible to prevent any possible
malfunction.

HOW TO REPLACE THE KEYBOARD'S BATTERY
The miniature lithium battery SEIKO (SEIZAIKEN) CR2016, Maxell CR2016,
Sanyo CR2016, or Matsushita BR2016 which powers your keyboard should last
approximately 5 years. However, because the battery in your keyboard is inserted
at the factory, its actual life once in your possession may be less than the speci-
