The factory default setting for all five functions—including the source of the
default settings—is 0.
To change any or all settings to your choice(s), you must first change the setting
of Option 0 from 0 to 1. Opportunities to change the settings of the other four
functions from their factory defaults are then made available in order, from
Option 0 to Option 4. As each Option is presented, you can change its setting or
leave the existing setting unchanged. In either case, you must confirm (save)
the setting to allow the sequence to continue.
It’s important to understand that in Setup mode you have 30 seconds to
confirm the setting of each Option. If you take longer than 30 seconds to
confirm any setting, the MMD900 will automatically exit Setup mode and enter
Measurement mode.
