Adding Memory
ICs must be inserted with the
beveled corner facing the rear
of the unit.
Installing four 1M x 4 bit ZIP ICs increases
JamMan memory from 8 to 32 seconds.

Before performing the memory upgrade procedure, disconnect JamMan from its power supply.
Installing the memory upgrade is not dif-
ficult, but care should be taken in handling
ICs, as well as in disassembling and reas-
sembling your unit. ICs can be damaged by
static electricity, and incorrect insertion can
damage both the IC and your unit. Observe
the following precautions:
• Keep parts in original containers until ready for
use.
• Avoid plastic, vinyl or styrofoam in the work
area.
• Discharge personal static before handling.
• Minimize handling; avoid touching IC pins.
• Do not slide ICs over any surface.
• Insert ICs with the proper orientation.
• Watch for bent pins on ICs.
