8.  SOFTWARE
This section contains a description of Tech 2 software, based on the latest product information available at 
the time of publication. Tech 2 flowcharts are provided on the following pages to give you an overview of 
the many Tech 2 software options. 
The section continues with a look at Tool Options on page 8-6 and Getting Started on page 8-13 to 
familiarize you with the various tool settings and to provide you with useful operation information. Next, 
you can see how to use Techline Information System 2000 (TIS 2000) on page 8-15 to perform service 
programming, Tech 2 updates, and snapshot procedures. Finally, comprehensive Tech 2 Pathing Tables on 
page 8-43 help you navigate to specific special functions that the Tech 2 offers. 
NOTEProper PCMCIA updates are essential for successful vehicle diagnoses. 
Refer to function F5: Programming Tech 2 on page 8-11 and PCMCIA 
Card on page 8-26.

F0: Set Clock 
After F0: Set Clock is selected, a Set Real-Time Clock menu appears (Figure 8-3). 
The following methods are available to select areas you need to change: 
• Use the up and down arrow keys to move the cursor to desired selection. Press ENTER to change the 
value. Each time ENTER is pressed, the value increases by one unit until a preset maximum unit is 
reached. Once all correct values are entered, press the soft key below Set Clock to save all changes. 
• Use the function key of desired selection to change an incorrect value. Each time the function key is 
pressed the value increased by one unit until a preset maximum is reached. Once all correct values are 
entered, press the soft key below Set Clock to save all changes.

F1: Set Screen Contrast 
After you select F1: Set Screen Contrast, a Set Contrast Control screen appears (Figure 8-4), providing you 
with instructions on how to set the screen contrast. After you finish setting the screen contrast, press EXIT 
to save the contrast level for the next Tech 2 power up. 
Important: The Screen Contrast Control is designed to adjust the permanent default contrast setting of 
Tech 2 display. 
Because of the nature of the LCD (Liquid Crystal Display), you will experience some contrast variance. 
When the temperature of the Tech 2 increases the display brightens slightly. As the temperature of the Tech 
2 decreases, the display darkens. This variance is a characteristic of an LCD screen and should be considered 
normal operation. 
The screen contrast control setting described above may not account for the entire variance of operating 
temperatures. Set a default setting which is mid-range between the operating temperatures. Screen contrast 
may be adjusted during any function by pressing SHIFT and using the up and down arrows for adjustment. 
Periodic adjustments may be necessary, but settings outside of this application are only retained during the 
current power-up session.

F2: Set Units 
After you select F2: Set Units, a Set Units screen appears (Figure 8-5). The currently displayed unit (either 
Metric or English) is displayed to the right of Current Units Setting. Use the up and down arrow keys to 
move the cursor to the desired selection. At the desired selection, press ENTER to set or change the Current 
Units Setting. Once the setting is completed, press EXIT to save the current setting for the next Tech 2 
power up. 
F3: Self Test 
After you select F3: Self Test, a Tech 2 Self Test screen appears (Figure 8-6). Refer to Chapter 6 for 
complete information. 
Power Down Screen 
After completion of any Self Test, return to the Tech 2 Self Test menu screen. After pressing EXIT, a 
screen appears instructing you to turn the Tech 2 power off (Figure 8-7). Turn off the Tech 2 and turn back 
on to continue.
