Engines produce carbon monoxide, an odorless, poisonous gas that causes
slower reaction time and can lead to serious personal injury or loss of life.
SAFETY WARNINGS
Wear safety glasses and protective clothing.
NEVER smoke or allow a spark or flame in the vicinity of battery or
engine.
Have plenty of fresh water and soap nearby in case battery acid
contacts skin, clothing or eyes.
If battery acid contacts skin or clothing, wash immediately with soap
and water. If acid enters eye, immediately flush eye with running cold
water for at least ten minutes and get medical attention immediately.
Use caution when working with metallic tools to prevent sparks or short
circuits.
Remove any jewelry or watches before you start servicing the battery.
Keep hair, hands, and clothing as well as tester leads and cords away
from moving blades and belts.

General Introduction
OTOFIX BT1
Smart Touchscreen Battery Analyzer
The OTOFIX BT1 smart touchscreen battery analyzer is a full-featured battery
and starting/charging systems diagnostics tool. The OTOFIX BT1 uses a
technology called Adaptive Conductance to more accurately determine the
health of battery than traditional battery testers. The OTOFIX BT1 can quickly
display both voltage and health status of the existing battery, register a new
battery, and perform advanced battery and electrical diagnostics. The OTOFIX
BT1 is also an advanced diagnostics tool that can identify faults in all systems
and display live data relating to those faults. (The all systems diagnostics
function is available by subscription.) The easy-to-use Android-based
touchscreen tool provides Wi-Fi software updates as well as Wi-Fi printing and
sharing of the shop-customized reports which can be printed out with the built-
in thermal printer.
There are two main components to the OTOFIX BT1:
OTOFIX BT1 Tester — the smart touchscreen battery analyzer
OTOFIX V1 — Vehicle Communication Interface (VCI)
