1.4 R&TTE Directive
The ET750 is a class2 wireless device (R&TTE 1999/55/
EC) approved for use in Europe. In France, use of the
ET750 is only permissible indoors.
iIn non-European countries the corresponding nation-
al regulations on the operation of wireless devices
in the 2.4 GHz frequency band must be heeded (e.g.
WLAN or Bluetooth).

1 689 989 240 2015-09-25|Robert Bosch GmbH
1.5 Wireless link
!ET750 users are responsible for compliance with the
applicable directives and restrictions in the country
concerned.
1.5.1 Important information on
WLAN and Bluetooth
WLAN (Wireless Local Area Network) is the term used
to describe a wireless local network. Like Bluetooth,
WLAN provides a wireless link on the free 2.4 GHz ISM
band (ISM: Industrial, Scientific, Medical). This frequen-
cy range is subject to state legislation, can however be
used without a license in most countries. Consequently
a large number of applications and devices employ this
frequency band for transmission. This can result in fre-
quency interference.
Depending on ambient conditions, the WLAN link may
therefore deteriorate, e.g. in the case of Bluetooth links,
cordless telephones, radio-controlled thermometers,
radio-controlled garage door openers, radio-controlled
light switches or radio-controlled alarm systems.
iExtreme caution is to be taken if wearing pacemak-
ers or other vital electronic devices when using wire-
less systems, as proper functioning of these items
could be impaired.
Pay attention to the following to ensure the best pos-
sible connection:
RThe WLAN signal always tries to find the most direct
path. When setting up the PC/Laptop and access
point (see Sec.2.5.2), make sure there are as few
obstacles as possible (e.g. steel doors and concrete
walls) which could interfere with the signal from and
to the ET750.
RInside buildings, the range of the WLAN is also
greatly influenced by the construction materials
used. Conventional masonry, wooden walls and vari-
ous types of dry construction wall scarcely impair
the propagation of radio waves. Thin gypsum walls
are however problematic, as considerable amounts
of moisture may accumulate in the gypsum and
result in the absorption of radio signals. Metal walls
and concrete (in particular reinforced concrete)
largely block out radio waves. Cellar ceilings are
often impenetrable. Generally speaking, walls with
a lot of installed metal (e.g. pipes, wires) obstruct
radio waves.
RRadio reception is also impeded by large metal
objects such as radiators and window frames as well
as active sources of interference such as radio tele-
phones, motion detectors and microwave ovens.
RHuman beings are also an obstacle to wireless trans-
mission. It must therefore always be ensured that
no-one stands between the transmitter and receiver.
RWe advise having the network infrastructure in-
stalled and maintained by a network specialist.
RKeep the SSID and the codes for the wireless link
in a safe place. Make sure these data are readily to
hand in case faults occur.
RWe recommend a thorough inspection of the prem-
ises on commissioning: Establish where in the build-
ing the ET750 works properly and where the operat-
ing limits are.
RIf the ET750 is used inside a vehicle (Faraday cage),
wireless communication may be severely impeded.
RThe wireless link is affected by weather conditions.
The reception signal may therefore vary.
RPlease contact your network specialist for any que-
ries.
1.5.2 Notes on access point (WLAN)
An access point is an electronic device which acts as
an interface between a wireless network and a cable-
connected computer network. It provides a wireless
connection between the ET750, the PC/Laptop and a
printer.
iWe recommend using WLAN standard IEEE 802.11n
(data transmission rate max. 600 Mbps) for the
access point. The "extended range" function is not
supported.
iThe WLAN configuration always depends on the con-
figuration of the access point available.
Heed the following:
RThe access point should be located as centrally and
high up as possible, ideally under the ceiling. The
access point is not to be installed behind any metal-
lic objects, such as radiators or in a metal switch
cabinet.
RIf there is only one access point antenna, this should
face downwards towards the floor. If an access point
has several antennas, these should be in three-
dimensional arrangement.
RThe best and highest transmission rates are always
achieved if there is visual contact between the
ET750 and the access point.
RIn the event of a weak link it may be useful to
change the channel set on the access point. Where
possible avoid employing channels adjacent to those
already in use.
RIt is advisable to configure wireless communication
encoding at the access point.

2.3 Obligation of workshop operator
The workshop operator is obliged to ensure that all
measures geared towards the prevention of accidents,
industrial diseases, labor-related health risks are taken
and measures towards making the workplace fit for
people to work in are carried out.
Electrical engineering in Germany is subject to the
accident prevention regulations of the trade associa-
tion "Electrical Plant and Equipment as under DGUV
Vorschrift 3 (previously BGV A3)". In all other countries,
the applicable national regulations acts or decrees are
to be adhered to.
Basic rules
The workshop operator is bound to ensure that all
electrical equipment and operating material is set up,
modified and maintained by skilled electricians only
or under the guidance and supervision of a skilled
electrician in accordance with electrical engineering
principles.
Furthermore, the workshop operator must ensure that
all electrical equipment and operating material is oper-
ated in keeping with electrical engineering principles.
If a piece of electrical equipment or operating material
is found to be defective, i.e. it does not or no longer
complies with electrical engineering principles, the
workshop operator must ensure that the fault is recti-
fied immediately and, in the event that imminent danger
exists, also ensure that the electrical equipment or the
electrical operating material is not used.
Tests (taking Germany as an example):
RThe workshop operator must ensure that all electri-
cal systems and equipment are tested by a qualified
electrician or under the guidance of a qualified elec-
trician to ensure they are in proper working order:
$Before starting for the first time.
$After modification or repair before starting for
the first time.
$At given intervals. Set intervals such as to ensure
that faults that can be expected to occur are
determined in good time.
RThe test is to take the electrical engineering prin-
ciples relating hereto into account.
RUpon request of the trade association, a test manual
is to be maintained into which specific entries are
made.

3. Safety instructions
3.1 Risk of electric shocks
3.1.1 Low voltages, high voltages
Hazardous voltages occur in both the lighting
system and the electrical system of a motor
vehicle. If contact is made with live parts
(e.g. with the ignition coil), there is a risk of
electric shock from flashover voltages caused
by damaged insulation (e.g. ignition cables
which have been attacked by martens). These
apply to the secondary and primary sides of
the ignition system, the wiring harness with
connectors, lighting system (Litronic) as well
as connection to the vehicle.
Safety measures:
¶Only connect to a properly grounded outlet.
¶Only the enclosed or a tested power supply cable is
to be used.
¶All extension cables must be fitted with shock-proof
contacts.
¶Do not exceed the voltage limits as specified on the
connection cables.
¶Any cables with damaged insulation must be re-
placed.
¶Check the electrical equipment every two years and
immediately deal with any problems.
¶Only use fuses with specified current ratings.
¶Before connecting it to the vehicle, first connect the
product to the lighting mains and switch on.
¶Before switching on the ignition connect the (B-)
cable to engine ground or the battery (B–) terminal.
¶Always switch off the ignition before performing any
work on the electrical system of the vehicle. Inter-
vention includes, for instance, connection to the
vehicle, replacement of ignition system components,
removal of equipment (e. g. alternators), connection
of equipment to a test bench.
¶Wherever possible, tests and settings should always
be caried out with the ignition switched off and the
engine stationary.
¶If tests or settings are carried out with the ignition
switched on or the engine running, care must be
taken not to touch any live parts. This applies to all
connection cables and leads as well as to connec-
tions of equipment to test benches.
¶Test connections must always be made using suit-
able connectors (e.g. Bosch testing cable set or
vehicle-specific adapter cables).
¶Make sure that all test connections are properly
plugged in and secure.
¶Before disconnecting the (B-) cable from the engine
ground or battery (B–), switch off the ignition.
¶Never open the enclosures.
3.1.2 High voltages in hybrid vehicles and electric ve-
hicles as well as their high-voltage components
If high-voltage components or high-voltage
wires are inexpertly handled, there is a risk of
fatal injury from high voltages and the possi-
ble transmission of current through the body.
¶Deenergization is only to be performed by
a qualified electrician, a qualified electri-
cian for specific tasks (hybrid) or a power
systems engineer.
¶Work on vehicles with high-voltage com-
ponents is only ever to be performed in
a safe, deenergized condition by persons
with the minimum qualification "Trained to
perform electrical work".
¶Even after deactivating the high-voltage
vehicle electrical system, the high-voltage
battery may still be live.
¶Operating condition cannot be established
from any running noise, as the electric ma-
chine is silent when stationary.
¶In gear positions "P" and "N" the engine
or electric motor may start spontaneously
depending on the charge of the high-voltage
battery.
Safety measures:
¶Never open or damage high-voltage batteries.
¶On accident vehicles, never touch high-voltage com-
ponents or exposed high-voltage wires before deac-
tivating the high-voltage vehicle electrical system.
¶Avoid contact with any high-voltage components
and high-voltage wires (orange sheathing) when in
operation.
¶Secure against unauthorized renewed start-up
(e.g. by means of a padlock).
¶After each switch off of the high-voltage system,
observe a waiting time of 5 minutes (depending
on the manufacturer's instructions). Subsequently
ascertain the absence of voltage using a suitable
testing device.
¶Visually inspect the high-voltage components and
high-voltage wires for damage. The power systems
engineer responsible should always be immediately
notified of any irregularities, doubts or defects
found.
$High-voltage components must never exhibit
signs of external damage.
$The insulation of the high-voltage wiring must be
intact and undamaged.
$Watch out for any abnormal deformation of the
high-voltage wiring.

3.2 Danger of acid burning
When exhaust gas measurements are taken,
the sampling hoses which are used release
a highly caustic gas (hydrogen fluoride) that
can cause acid burning in the respiratory sys-
tem when heated to temperatures in excess of
250 °C (482 °F) or in the event of fire.
Rules of conduct:
¶Consult a doctor immediately after inhaling!
¶Always wear gloves made of neoprene or PVC when
removing residues left after a fire.
¶Neutralize any residues left after a fire with a cal-
cium hydroxide solution. This produces non-toxic
calcium fluoride, which can be washed away.
Acids and alkalis can cause severe burning on
unprotected skin. Hydrogen fluoride in combi-
nation with moisture (water) forms hydroflu-
oric acid. The condensate, which accumulates
in the sampling hose and in the condensate
container likewise contains acid.
Rules of conduct:
¶When replacing the O2measuring sensor, bear in
mind that it contains alkali.
¶When replacing the NO measuring sensor, bear in
mind that it contains acid.
¶Rinse any affected parts of the skin immediately in
water, then consult a doctor!
¶NO and O2measuring sensors are hazardous waste
and must be disposed of separately. Your Bosch
specialist equipper can dispose of sensors in the
proper manner.
If fluid (electrolyte) escapes from batteries
and rechargeable batteries
, avoid getting it on
your skin or in your eyes.
Rules of conduct:
¶If contact with skin or eyes happens nevertheless,
wash the affected parts immediately with clean wa-
ter and then consult a doctor.
3.3 Danger of injury, Danger of crushing
The vehicle has rotating and moving parts
that can injure fingers and arms.
If the vehicle is not prevented from roll-
ing away, there is a danger of people being
crushed against a workbench, for example.
There is the risk with electrically operated
fans in particular that the fan can start run-
ning unexpectedly even when the engine and
ignition are off.
Safety measures:
¶Take steps to prevent the vehicle from rolling away
while it is being tested. Select the park position if the
vehicle has an automatic transmission and apply the
handbrake or lock the wheels with chocks (wedges).
¶Deactivate the start/stop system when working on a
vehicle in order to prevent uncontrolled engine start.
¶Operating staff must wear work clothes without
loose bands and loops.
¶Do not reach in any area with rotating or moving parts.
¶When working on or in the vicinity of electrically
driven fans, allow the engine to cool down first, then
disconnect the plug of the fan motor.
¶Route cables at a suitable distance from rotating parts.
¶Secure the trolley against rolling away by setting the
brakes.
¶Do not place heavy objects on or lean on the sensor
holder.
¶Transport and operate the equipment only in accor-
dance with the operating instructions.
Safety instructions | ET750 | 9 en

1 689 989 240 2015-09-25| Robert Bosch GmbH
3.4 Danger of burning
When working on a hot engine, there is a risk
of injury from burning if such components as
the exhaust gas manifold, the turbo-charger,
the Lambda sensor, etc. are touched or if
parts of the body come too close to them.
These components may be heated to tem-
peratures of several hundred degrees Celsius.
Depending on the duration of the exhaust
gas measurements, the sampling probe of the
exhaust gas measuring instrument may also
become extremely hot.
Safety measures::
¶Always wear protective clothing, e.g. gloves.
¶Allow the engine to cool down first. This also applies
to auxiliary heating systems.
¶Keep connecting cables well away from all hot parts.
¶Do not leave the engine running any longer than
necessary for the test or setting.
3.5 Danger of fire, Danger of explosion
There is a risk of fire and explosion from fu-
els and fuel vapors when work is performed
on the fuel system or on the mixture control
system.
Safety measures:
¶Switch off the ignition.
¶Allow the engine to cool down first.
¶Avoid naked flames and potential sources of sparks.
¶Do not smoke.
¶Collect any leaked fuel.
¶Always ensure effective ventilation and suction when
working in closed areas.
3.6 Danger of asphyxiation
Car exhaust fumes contain carbon monoxide
(CO) - a colorless, odorless gas. If inhaled,
carbon monoxide causes an oxygen deficiency
in the body. Extreme caution is therefore es-
sential when working in a pit, as some of the
components of the exhaust gas are heavier
than air and settle at the bottom of the pit.
Caution is also necessary when working on
LPG-driven vehicles.
Safety measures:
¶Always ensure effective ventilation and suction (es-
pecially when working in a pit).
¶Always switch on and connect the suction plant in a
closed area.
3.7 Danger of tripping
When conducting tests or making adjust-
ments, the sensor and connection cables in-
crease the risk of tripping.
Safety measures:
¶Route the connecting cables such that any risk of
tripping up is prevented.
3.8 Noise
Noise levels in excess of 70 dB(A) can occur
when measurements are carried out on a ve-
hicle, especially at high engine speeds. Dam-
age to hearing may result if human beings
are exposed to noise at such levels over an
extended period of time.
Safety measures:
¶Noise protection facilities must be provided by the own-
er at all workplaces in the vicinity of the testing area.
¶Suitable personal noise protection facilities must be
used by the operator.

5.2 Connection
Prior to the initial commissioning, make sure the mains
voltage coincides with the voltage specified on the pow-
er supply unit (use the power supply cable provided).
4.6.1 Notes on control unit diagnosis
The ET650 is supplied with voltage either via the power
supply unit provided or the OBD interface in the vehicle.
!If a test step involves starting the engine, the battery
voltage may drop to such an extent that supply via
the vehicle is no longer guaranteed. In such cases
it may be necessary to run the ET650 by way of the
power supply unit.
iOn some vehicles, the ignition must be switched on
for power to be supplied via the OBD interface.
Connection to the diagnostic interface in the vehicle is
done using the OBD connection cable (fig. 6, item. 2).
!Make sure the OBD connection cable is properly
connected to the ET650. Incorrect connection could
cause the pins of the plug to bend or break off. Only
use the OBD connection cable contained in the
scope of delivery of the ET750.
iNotes on control unit diagnosis can be found in the
online help for the HUB software ( ).
4.6.2 Firmware update
After an update of HUB, the firmware of the ET650 is
updated automatically when the control unit diagnosis
is started.
