SAFETY AND WARNING NOTES

This paragraph contains important safety and warning notes for handling and operating the device in series applications.

WARNING indicates a hazardous situation which, if not avoided, could result in death or serious injury.

CAUTION indicates a hazardous situation which, if not avoided, could result in minor or moderate injury.

NOTICE is used to address practice not related to physical injury.

• The product will be provided and approved for a rated voltage of 12/24 volts. Short circuits must be securely prevented, even in the event of a fault. Creeping short-circuits lead to high arc energies that cannot be switched off by conventional melting fuses. If other rated voltages are present in the vehicle (e.g. 24/48 V for example in hybrid vehicles, or 400/800 V in electric vehicles) we recommend that safety precautions are taken in the vehicle itself (e.g. additional insulation of high voltage lines and the use of edge protectors when passing through sharp-edged areas, in order to prevent short circuits to inputs/outputs of our device, e. g. to loudspeaker lines).
• No moving pictures/movies/videos should be visible for the driver during driving. Visibility of the co-driver monitor/display must be disabled (e.g. by activating the switchable privacy technology when driving).
• The product emits invisible infrared radiation which might cause damage to the human eye and skin. Therefore, the customer shall perform a risk assessment according to target-market specific regulations and shall instruct its personnel accordingly. Furthermore, the customer shall inform and instruct the end-user (e.g. via entry in the manual) about the emitted radiation, the corresponding risks and countermeasures. Bosch will support on request.

• The product is intended, and has been approved, for installation and operation in vehicles with a rated voltage of 12/24 volts. It may be necessary to adapt the product’s factory-set state to suit the specific country.
• Only connecting cables and external devices that are appropriate for the device in question may be used (e.g.: proper current carrying capability, proper EMC shielding, flammability verified with appropriate certificates). Compliance with the applicable standards can no longer be guaranteed if the device – including the software – is modified without the agreement of Bosch.
• Bosch assumes no responsibility for damage as a result of incorrect indicators/displays. These may arise if the device has not been connected or has been incorrectly connected, or if the device receives false or erroneous signals from the system.

• Formation of condensation on the device must be avoided. In case of condensation formation, you must allow an acclimatization time of up to two hours to pass.
• Do not cover ventilation openings and heat sinks. Otherwise, a build-up of heat that could lead to malfunction may occur in the device.
• Do not insert foreign bodies into the insertion slots or openings of the device. Injury, or damage to the device, may occur otherwise.
• The device must not come into contact with hot or burning objects (e.g. cigarettes).
• To clean the device, never use hard or sharp objects that could damage the protective pane or housing. Do not use aggressive cleaning agents such as thinners, gasoline, abrasive cleaners, spray cleaners, acidic or alkaline solutions, or wax. Do not spray any liquids onto the device. To clean the housing and protective pane / display, moisten a soft cloth with tepid water and wipe off the dirt. Make sure that no liquid enters the inside of the display. Afterwards, wipe the cleaned surface with a clean, dry cloth.
• If the device is to be cleaned before installation in the vehicle, you must make sure the openings (in particular the connector contact points) are kept sealed so that no liquid can enter the device.
• Any media compatibility test (such as a single wetting with gasoline) that may be referred to in Chapter 4.5 (Chemical Characteristics) does not represent an extension to the permitted cleaning agents.
• Camera Window shall not be covered or obstructed. Do not position/keep any objects in front or near the camera window. Doing such will compromise the Driver Drowsiness and Attention Warning function. (This information is also relevant to the End User, we recommend respective note in the Vehicle User Manual)
• The customer must ensure that Bluetooth/WiFi functionality is always configured according to target market specific regulations, e.g. with regards to receiving frequency bands. The customer must ensure correct configuration of frequency bands in case of SW updates.
• The customer must ensure that GNSS functionalities are configured according to regulations of different target markets, e.g. US (e.g. GLONASS requires licensing), RUS (GLONASS), China (e.g. encryption of positioning information required).

Used WLAN Modes:

• Station Mode (STA)
  • Device does connect to external AP on DFS Channels
• Access Point Mode (AP)
  • DFS channels are not used

INSTALLATION

Assembly

The CTP devices are air cooled. The customer must ensure that a heat exchange with the environment is possible. The operating mode “sleeping“ applies for either completely disconnected from power supply or for connected to power supply with only the co-processor running (main processor powered down).

The product’s operating safety is only ensured if the permissible conditions are maintained. Voltage supply and grounding: Make sure that the loudspeaker cables do not have any contact to ground (earth, negative terminal of the vehicle battery). Observe the correct sequence when connecting to /disconnecting from the vehicle’s electrical system. Do not knock the unit during installation. In particular, do not exert pressure on the screen area to push the unit into its final position. Instead press the four corners of the bezel and let the unit slide into the opening.

Permitted Use

The CTP3NA may only be used within the conditions (environment, application, installation, loads, see e.g. chapter 9) as described in this TCD and the agreed upon documents. Only connecting cables and external devices that are appropriate for the device in question as regards safety, electromagnetic compatibility and grade of shielding may be used (see e.g. section “4.5 Aerials”. Compliance with the applicable standards can no longer be guaranteed if the device is modified without the agreement of Bosch.

Improper Use

All use outside the permitted conditions of use constitutes improper use and is therefore not permissible. Bosch does not accept liability for damage caused by improper use.

The following examples of foreseeable misuse constitute improper use:

• The customer must not use the Digital I/Os and the RS-232 to control functions that are not consistent with the “QM” rating of the CTP3NA.
• The customer must take appropriate measures to ensure that the audio mute function does not suppress safety relevant messages.
• The customer must only use splitters for the GPS antenna that contain diodes to prevent that current flows from one device connected to the splitter into another device.
• Use in vehicles with 24V rated power without central load dump suppression.
• Use outside the approved operational characteristics stipulated in this document or the appendixes (with the exception of customer-specific approvals)
• Modification of the factory settings by unauthorized persons
• Use of add-on components
• Use in watercraft, aircraft and spacecraft and in aggressive atmospheres

Bosch must be notified about all changes to the environment of the product that deviate from the TCD and the agreed documents. Such use or application of the product may only take place after approval has been provided by Bosch on the basis of the changed environment and the deviation from the TCD. If the device is connected incorrectly, it may draw the full operating current even when switched off. In this case, without any further deactivation on the vehicle side, there is a risk of battery depletion. No liability is assumed for any damage occurring as a result of this.
