Configuration
All Serial Communication parameters are em-
bedded in a user menu consisting of 5 separate
menu selections, each with its own sub-menu of
choices. If your scale is connected by RS-232
serial communication lines to other equipment,
or you wish to disable the
lb/kg
key, you may
have to modify some or all of these parame-
ters. To modify these parameters, you must first
enter the USER MENU mode. Once there, four
of the front panel keys become directional navi-
gators to move around in the menus, and one
key is used to save or SET the selections. Com-
plete directions are found below.
To place the unit in USER MENU mode:
þ
Turn the scale off.

While holding down the
lb/kg
key, turn the scale back on.

When the display shows "
A1
",
the unit is in USER MENU
mode, and you can release the
lb/kg
key. Shown at right are the
directional and SET key assign-
ments.
