Maintenance
Aside from normal care in handling and use, your Forte SE requires no regular maintenance.
Clean with a soft cloth dampened with water. Never use abrasives or solvents as they
may damage the unit’s paint, markings and display lens. There are no batteries inside to
replace—ever. Instead of volatile SRAM used in most other instruments, your Forte SE uses
nonvolatile Flash Memory for storage, which retains information without power.
Common Problems
Below is a list of the most commonly encountered problems and diagnoses for each.
Power Problems
This is the normal power-up sequence:
1. The display backlight turns on.
2. “Loading...” appears on the display for a few seconds.
3. The Forte SE enters Program Mode with Program 1 or the default boot up program
selected.
If nothing at all happens when you turn the power switch on, check if one of the following
might be the issue:
The power cable is not plugged
securely into the wall outlet.
Plug the power cable securely into the wall
outlet.
The power cable is not plugged
securely into the Forte SE power jack.
Plug the power cable securely into the Forte
SE power jack.
