DANGER
If the coin-cell battery is incorrectly replaced, there is danger of an explosion. The coin-cell battery
contains a small amount of harmful substances. To avoid possible injury:

• Do not expose it to excessive heat.
• Do not expose it to water or rain.
• Do not short-circuit it.
• Do not drop, crush, puncture the battery, or make it subject to strong forces. Battery abuse or
mishandling can cause the battery to overheat, which can cause gasses or flame to "vent"
from the battery or coin-cell battery.
To replace the coin-cell battery, do the following:
1. Turn off the computer; then disconnect the ac power adapter and all cables from the computer. Wait
several minutes to let the computer cool.
