Battery Replacement
The K2600 uses a 3-volt lithium coin-cell battery (CR2032) for program RAM backup (sample
RAM is not battery-backed). Unlike a typical alkaline batteryÑwhose voltage output declines
over the life of the batteryÑa lithium cell maintains a stable voltage until itÕs almost out of
power. Once it has used up almost all of its power, however, its voltage drops rapidly.
Consequently, to avoid the risk of losing the contents of your program RAM, you should replace
the battery as soon as your K2600 warns of low battery voltage.
The battery in your K2600 will last for several years (fewer if you add the P/RAM-26 option,
which approximately doubles the load on the battery).YouÕll know the battery is losing power
when the display says BATTERY VOLTAGE IS LOW during powerup. When you see this
warning, replace the battery as soon as possible.
Replacing the battery requires you to open an access panel on the underside of your instrument.
This is the same panel you would open to install program RAM (P/RAM-26), sample RAM, or
ROM sound block options.
