Display Overview
The PC-2001 is a portable timing system with 11 programmable functions. Though external
power and signal can be applied, the control and power systems are entirely self-contained.

Manufactured in two models, the outdoor version of the timing display is designated as PC-
2001-11, while the indoor unit is designated PC-2001-13.
The timing display is powered by 12 V batteries. Detachable power cord/transformer
assemblies also permit operation of the PC-2001 with 120 or 230 V AC. The unit draws 1 A of
power. The enclosed batteries (two in the outdoor model and one in the indoor display) are
rechargeable and have a built-in charger.
