Introduction
THINGS YOU SHOULD KNOW
CAUTION!
CAUTION
CAUTION!
CAUTION
When performing any checks with the engine running in an enclosed space
such as a garage, make sure there is proper ventilation. Never inhale
exhaust gases; they contain carbon monoxide, a colorless, odorless,
extremely dangerous gas that can cause unconsciousness or death.
To help avoid personal injury, always set the parking brake securely and
block the drive wheels before performing any checks or repairs on the
vehicle.
TECH 2 DISCLAIMER
The Tech 2 is designed for use by trained service personnel only. It has been developed for the sole purpose
of diagnosing and repairing automotive systems with electronic controls and interfaces. Every attempt has
been made to provide complete and accurate technical information based on factory service information
available at the time of publication. However, the right is reserved to make changes at any time without
notice.
FCC COMPLIANCE
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to
Part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial environment. This equipment generates, uses,
and can radiate radio frequency energy. If not installed and used in accordance with the instruction manual,
it may cause harmful interference to radio communications. Operation of this equipment in a residential area
is likely to cause harmful interference, in which case the user will be required to correct the interference at
his or her own expense.
Page 1-2 Tech 2
Introduction

may cause unacceptable radio or TV interference.
CAUTION!
CAUTION
NOTE
The Tech 2 uses parts that can produce arcs or sparks. When used in a
garage environment, the Tech 2 must be located not less than 18 inches
(460 mm) above the floor.
• Do NOT clasp battery clips together when connected simultaneously
to the vehicle's 12-volt cigarette lighter or power supply. Reverse
polarity in the vehicle's cigarette lighter may be present. Damage may
occur to the Tech 2 or to the vehicle.
• If power is applied to the Tech 2 and the display remains blank,
reverse polarity in the cigarette lighter may be present. Damage to the
Tech 2 could occur. Do NOT connect the DLC cable to the vehicle.
Verify that the center contact of the vehicle's cigarette lighter has +12
volts and that the outer contact is grounded.
• Turn off the power before inserting or removing the PCMCIA card.
Continual removal and reinsertion of this card is not recommended.
• Align all cards and components carefully before inserting them into
the Tech 2.
• Make sure all cables and adapters are firmly connected before starting
to use the Tech 2.
• Always read the instructions completely before attempting a new
procedure.
• Do not connect the RS-232 and RS-485 ports to a direct phone line.
The Tech 2 was not designed for this method of communication.
• Do not place the Tech 2 so that the tilt stand can make contact with the
vehicle battery terminal as this could short out the battery.
TAKING THE PRODUCT BACK AND RECYCLING
Applicable to product that is sold into the European Union, the European Union has passed a directive
called Waste Electrical and Electronic Equipment, or WEEE for short, to ensure that systems are setup
throughout the EU for the collection, treating and recycling of electronic waste.
Te ch 2 Page 1-3
Introduction
This ensures that the devices are recycled in a resource-saving way representing no danger to health or the
environment.
FIGURE 1-1. WEEE Logo
The WEEE symbol (see Figure 1-1) on the product or its packaging shows that the product must not be
disposed of as residual garbage. The user is obliged to collect the old devices separately and return them to
the WEEE take-back system for recycling.
The WEEE directive concerns all Bosch devices but not external cables or batteries. For more information

2. CARE AND CLEANING
After using the Tech 2, a few simple steps will insure that you get the most life out of this diagnostic tool.
NOTE
Although the Tech 2 is water resistant, it is not waterproof, so be sure to dry the Tech 2 thoroughly prior to
usage and/or storage.
Do not spray or pour cleaner anywhere on the Tech 2. If the Tech 2
becomes dirty, clean it with mild detergent or hand soap. Avoid using
harsh solvents, such as petroleum-based cleaning agents, acetone, benzene,
trichlorethylene, etc. Harsh solvents can etch Tech 2 plastic surfaces.
Maintenance of the Tech 2 requires periodic inspection and cleaning of the following:
• The display window
• The keypad
• The cable assemblies and connectors
Make sure the Tech 2 is not connected to a vehicle or other power source and follow the cleaning procedures
detailed below.
CLEANING THE DISPLAY
The display collects dust and grime during normal use. Occasionally wipe the screen with a clean, soft,
static-free cloth. Remove stubborn stains by applying a non-abrasive glass cleaner to a soft cloth and wipe
the cloth across the display area.
Te ch 2 Page 2-1
