2.0 PRECAUTIONS
Do not turn off the main power or pull the power cord from the wall outlet without first
turning off the POWER switch CB1 located on the back of the unit.
The TechSetter employs only low voltage power supplies. However, hazardous voltages
are present in the motor driver and in the AC input wiring. Reasonable safety precautions
should be used to avoid electrical shock. Turn the unit off before replacing the media
supply roll or servicing any component.
Circuits installed on the thermal print head are composed of CMOS ICs. Care must be
taken during operation and service to avoid damage from static electricity. When
replacing the print head, conductive mats and grounding straps should be used to
prevent damage due to electrostatic discharges (ESD).
The print head may become dirty even after short periods of operation. Clean the print
head each time a new roll of media is installed. Turn the power off and clean the print
head with the alcohol saturated pads supplied with the unit. Allow time for the alcohol to
evaporate before turning the power on again.
Never attempt to operate the unit without media moving across the print head! Such a
condition may cause severe damage and void the warranty.
3.0 CONTROL PANEL KEYPAD FUNCTIONS
To access control panel selections, the TechSetter must be taken off line by toggling the
ON LINE key once. The green ONLINE light will go off, and the "OFF LINE" message
will be displayed. The layout of the control panel is shown in Fig. 3.
3.1 Front Panel Indicators
There are two LED indicators (ON LINE and STATUS) on the panel. Both indicators
are bi-color (green and red).
When the ON LINE indicator is lit green, the TechSetter is in On Line state and ready to
accept data; when it goes off, the TechSetter is in OFF LINE state and can go to the
MENU or ITEM mode to change parameters.
If the TechSetter detects any error, the STATUS indicator will be lit red. An error
message will also be shown on the VF display. See Section 5 for detailed error messages.
The TechSetter will not accept any data when the STATUS indicator is lit red with error
message displayed. A flashing red color STATUS indicator means WARNING! The
warning message will be seen on the VF display (such as "Low Media"). The STATUS
