CELLULAR PHONE AND TWO-WAY RADIO OPERATION

Cellular Phones and Portable Two-Way Radios with Separate External Antenna

  1. Radio remote controls (garage door opener) and wireless units (keyboard or PC mouse) may only be used in the vehicle if the transmitted output is maximum 100 mW.
  2. Please follow exactly the operating instructions and installation instructions of the manufacturer of mobile telephones, radio-based devices, and antennas.
  3. The devices' optimal range will only be reached with an exterior antenna.
  4. When telephone and two-way radio systems are installed properly, there is no danger to safety systems such as the ABS or the airbag. A prerequisite is however that there has been no intervention in their installations. Parallel wiring to such systems must be avoided.
  5. Excessively high electromagnetic fields can arise if mobile telephones and radio devices, with or without an incorrectly installed exterior antenna, are used.

NOTES ON OPERATION

  1. Never remove the memory device if you have selected the USB connection baseplate as the source. It may destroy the storage medium.
  2. Do not insert an MP3 player directly in the USB connection baseplate, the connection could be damaged. Always use a USB extension cable instead.
  3. Do not connect any other devises to the USB connection baseplate other than a USB memory stick or an MP3 player. It is not possible to play hard drives or USB hubs via the USB connection baseplate.
  4. The maximum input of the USB memory device must not exceed 2.5 W (500 mA/5 V).
  5. Never insert metal objects into the USB connection baseplate. They may cause a short circuit and damage the unit.
  6. If the USB connection baseplate does not recognize the device after 15 seconds, remove the device and insert it again.
  7. Some MP3 players must be activated with a button to create the USB connection. Refer to the Operating Instructions.
  8. The permissible temperature range of USB sticks and MP3 players is limited and often lies between 0° C and 40° C. For this reason, inform the customer that the storage medium must not be left in the vehicle for extended periods.
