Replacing The Clock/Cmos Ram Battery - Viglen Vig680M Manual

Replacing the Clock/CMOS RAM Battery

A lithium battery is installed in a socket on the system board.
The battery has an estimated life expectancy of seven years. When the battery starts to
weaken, it loses voltage; when the voltage drops below a certain level, the system
settings stored in CMOS RAM (for example, the date and time) may be wrong.
If the battery fails, you will need to replace it with a CR2032 battery or an equivalent. As
long as local ordinance permits, you may dispose of individual batteries as normal
rubbish. Do not expose batteries to excessive heat or any naked flame. Keep all
batteries away from children.
CAUTION!
Danger of explosion if the battery is incorrectly replaced. Replace only with the same or
equivalent type recommended by Viglen. Discard used batteries according to
manufacturer's instructions.
To replace the battery, carry out the following:
1. Observe the precautions in "Before You Begin."
2. Turn off all peripheral devices connected to the system.
3. Turn off the system.
4. Remove any components that are blocking access to the battery.
5. Figure 29, 1 shows the battery location. Gently pry the battery free from its socket,
taking care to note the "+" and "-" orientation of the battery (Figure 28, 2).
6. Install the new battery in the socket.
