Instruction Manual

Overview

This JSL-72 timer is specifically designed for controlling coffee grinder. It can

count from 0.01" to 99.99" or from 1" to 99'59". Counting direction can be set

by user (counting up or counting down). Accumulated time/ cups can be

automatically stored in the timer and reset by user. Operating function modes

include single dose, double dose and manual. Most function features can be

activated by front key pad or remote switch. However, manual function can

only be accessed through remote switch. Three different display modes can be

programmed. User can shift among single/double dose display mode, total

running time display mode, and total number of cups display mode. Timer

adjust function can be deactivated to prevent any accidental change.
