486-OCV Plus
Installation Overview u 2-12
Jumper J11
Internal Battery/CMOS Clean Select
The 486-OCV Plus comes with an internal battery. If
there is a problem with the internal battery, or if you
prefer to connect an external battery, set Jumper J11
pins 1-2-3 to Off and connect an external battery to
Connector J10.
If, for some reason, the CMOS becomes corrupted, the
system can be reconfigured with the default values
stored in the ROM chips. To load the default values, set
J11 pins 2 and 3 to On for approximately one to two
days, then return to the default position.
Note:
After CMOS has been reset, you must either set the
jumper to Internal or External battery enable. If you
set the jumper to External battery enable, make sure
you connect an external battery to Connector J10.
