Symptoms/Issue
Can I change the SRAM battery in my Expression 3 while the console is running?
Description/Explanation of Issue
Yes, the SRAM battery, which is a CR2477 battery (ETC part number: BT137) can be changed while the console is
powered on. If you suspect your SRAM battery is dead, you may lose your show file if your console loses power or gets
turned off. This is especially important if you do not have a backup of your show file.
Fix/Solution
1. Open the Expression 3 by turning the bottom two knobs on each side of your console, and then lifting the face
panel.
2. Find the CPU tray, which will be located in the center of the console, and unscrew the five screws holding the
top of the tray. Inside will be the CPU board. The battery will be located near the edge of the CPU board
closest to the front of the console.
3. Remove the old battery, and replace it with the new one.
4. Place the top of the tray back in it's original position and screw it down using the five screws that we removed in
Step 2.
5. Close your console by lowering the face panel and tightening the knobs on each side of the console.
