Description
- The 1240 and 1241 retain configurations by the use of battery backed RAM. In most instruments the battery is a Catalyst Research 3440LP Overtime this battery will deplete itself and leak. A leaking battery can destroy components, PCB traces and metal.
Fix
- WARNING! When taking the analyzer apart, users are at there own risk! The inside contains lethal voltages and no work must be done if the "active voltage" bulb is flashing. Once the lid is removed it can be found on the top of the device behind the CRT.
- The old battery can be de-soldered and wires can be soldered in to lead to a new battery. It is up to the user to decide what type of battery they will use. As long as the battery voltage is in around 2.8V. The new battery can be placed where ever is appropriate.

- So far I've had no problem with this fix I've had the battery installed for over a year. I used a CR2032 battery, but it's not the best solution because the analyzer will try to recharge it.
