3.10 Setting the CPU Dipswitches

Dipswitches are used to set 545/555 CPU operating parameters. The

dipswitches are located near the front of the CPU, behind the bezel or

battery door. See Figure 3-12. To gain access, lower the access door. With the

CPU in its (normal) vertical position, dipswitches pushed to the left are On;

dipswitches pushed to the right are Off.

Switch 9 is used to set the back-up battery On or Off. As Figure 3-12

indicates, moving the switch to the left enables the back-up battery; setting

the switch to the right disables the back-up battery.

NOTE: When SW9 is set to the On position, the battery LED indicates the

state of the battery back-up circuit. If the battery LED is illuminated,

memory contents should be maintained; if the LED is not illuminated,

memory contents will not be maintained.

Switch 10 is used to allow the CPU to perform an Auto Recompile during

runtime. Switch 10 is shipped in the disabled (left) position. To activate this

feature, set the switch to the right (enabled) position. Refer to Appendix F

for more information about the Auto Recompile function.
