CONTROL KEYS 
The [PWR] key is used to turn the Tech 2 on or off (Figure 3-15). The status indicator light above this key is 
illuminated green when the Tech 2 is operational. 
The [SHIFT] key is used with the up and down arrow keys to change screen brightness and contrast 
(Figure 3-15).
To adjust screen brightness and contrast, perform the following: 
1. Press the [SHIFT] key once (amber status indicator light above [SHIFT] lights up). 
2. Use up and down arrows to adjust screen brightness and contrast.
3. Press [SHIFT] key again when desired brightness is reached (status indicator light above [SHIFT] is

TECH 2 SOFT KEYS 
Four soft keys are located directly below the Tech 2 screen (Figure 3-16). The soft keys correspond directly 
to the four possible selection boxes found at the bottom region of the Tech 2 screen. These selections may 
change from screen to screen and are under the control of the application software. To make a screen 
selection, press the corresponding soft key. In the example shown in Figure 3-17, the first soft key was 
pressed to select [Display Time].

ACTION KEYS 
Action keys are used to respond to a specific question, initiate an action, or to exit from the Tech 2 program 
(Figure 3-20). Specific yes or no questions often appear on the Tech 2 screen. The [YES] and [NO] keys 
are used to respond to these questions. Either of the two [ENTER] keys may be pressed to activate a menu 
selection. Either of the two [EXIT] keys may be pressed to leave the current Tech 2 screen and return to a 
previous screen.

FUNCTION KEYS 
Ten function keys (F0 to F9) are located on the Tech 2 keypad (Figure 3-21). A function key may be pressed 
to initiate a specific Tech 2 function. In some cases the function keys are used for numeric data entry. The 
arrow keys and [ENTER] may also be used to initiate a function selection, however, this may require 
additional keystrokes.

TECH 2 CONNECTIONS TO VEHICLE 
The Tech 2 receives power through the DLC cable connection to vehicles equipped with On-Board 
Diagnostics (OBD II) (Figure 3-23). In the case of vehicles not equipped with OBD II, an external power 
source such as a vehicle cigarette lighter must be used (Figure 3-24).

TECH 2 CONNECTION TO PC 
It may be necessary to connect the Tech 2 with a PC for the following reasons: 
• Transfer of vehicle data (calibration information, snapshot, etc.) from the Tech 2 to the PC 
• Transfer of vehicle calibration data from the PC to the Tech 2 
• Transfer of data (software update, etc.) from the PC to the Tech 2 
• Before connecting Tech 2 to the PC, the following steps should be taken: 
• Make sure that the RS-232 cable (P/N 02001358) is attached to the Tech 2 RS-232 port located on the 
left side of the Tech 2 (Figure 5-3). 
• Make sure the appropriate power supply is connected to the DLC cable power jack connector (Figure 4-
1), or to the power jack connector at the bottom of the Tech 2 (Figure 3-25). 
• Make sure the PCMCIA card is fully inserted into the upper slot at the top of the Tech 2 (Figure 3-8, 
Figure 3-9, and Figure 3-10). 
Plug serial port adapter (P/N 01001089) into the unused serial port (com port) on the back of the computer 
terminal. Then plug the Tech 2s RS-232 cable into the serial port adapter and connect the appropriate power 
supply.
