Chapter 3 Getting Started
To get started using your ETHOS™ scan tool:
1. Supply power to the tool.
2. Turn on the unit.
3.1 Supplying Power
There are three ways to supply power to this scan tool:
• Install batteries
• Connect to vehicle power
• Connect to an AC/DC power supply
For related information, see “Power Supply” on page 8.
NOTE:
i To conserve batteries, we recommend always powering the unit from vehicle power or from
the AC/DC power supply.
3.2 Installing the Batteries
The scan tool comes with six alkaline AA batteries. Rechargeable nickel-metal hydride
(NiMH) batteries may also be used. Do not use standard (lead/zinc) batteries as they do not
provide sufficient power to operate the scan tool, and may leak and damage your ETHOS™.
For related information, see the following sections:
• “Battery Power” on page 9
• “Replacing the Batteries” on page 39
IMPORTANT:IMPORTANT:
Your scan tool will not operate and may be damaged if the battery polarity is incorrect. Refer
to the diagrams on the battery slots for correct battery polarity.
z To install the batteries:
1. Depress the two locking tabs of the battery cover on the back of the scan tool (Figure 2-4
on page 5).
2. Lift the cover off.
3. Observe correct polarity as shown by the diagrams on the battery slots (Figure 3-1), and
install the batteries.
