Attn: Motorola R2600A,B,C and D Service Monitor Warning -  If you have a Motorola R2600 unit, be sure to check the 3 V lithium battery on the CPU board. This battery seems to fail after about 9 years of use and they commonly LEAK ACID on to the CPU board causing random failures. The acid leak generally ruins the CPU board by getting underneath IC's and corroding traces inside the board. The battery is a Plainview PMC 3.6B and is available from battsco.com We recommend these get replaced every 6 years whether they need it or not.
