6. EC and FCC regulations

Most electronic equipment produces some undesired interference at a close distance. To make sure the increasing

numbers of electronic equipment will not cause harmful interference, the CE (Europe) and FCC (US) regulations state

very low levels of interference that should not be exceeded. The AMB equipment does not exceed these levels.

The CE regulations also state the levels of interference generated by other sources which the equipment must be able to

tolerate without malfunctioning. These levels are considerably higher than the interference levels produced by the

electronic equipment itself. Cellular telephones however may generate interference levels which may cause other

electronic equipment to malfunction. AMB made sure its equipment is insensitive to the interference generated by cellular

telephones or other modern fonms of personal radio communications.

The FCC regulations for Infonmation Technology equipment which must be printed in the manuals state that you must

tolerate interference produced by others and you must switch-off when interference produced by your equipment is

experienced by others. The level of interference is strongly reduced when you increase the distance between two pieces

of electronic equipment. For example: your portable radio will most probably experience interference when placed on top

of your monitor, but will work very well a few feet away. Since the AMB transponders operate on magnetic induction they

have no antenna, but a built-in coil instead. The transponders do not produce an electromagnetic (radio) wave but only a

magnetic wave. The difference between an electromagnetic (radio) wave and a magnetic wave is that the

electromagnetic wave travels by itself over great distances and the magnetic wave does not. As the distance increases

the strength of the magnetic wave is greatly reduced. This is why AMB transponders are no transmitters.

This equipment complies with part 15 of the FCC rules. Operation is subject to the following two conditions: (1) This

equipment may not cause harmful interference, and (2) this equipment must accept any interference received, including

interference that may cause undesired operation.

Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15

of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential

installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in

accordance with the instructions, may cause harmful interference to radio communications. However, there is no

guarantee that interference will not occur in a particular installation. If this equipment does cause hanmful interference to

radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try

to correct the interference by one or more of the following measures:

.Reorient or relocate the receiving antenna.

.Increase the separation between the equipment and receiver-

.Connect the equipment into an outlet on a circuit different from that to which the receiver is connected

,~§E!!:7 The AMB TranX 160 activated loop upgrade is specially designed to let an existing AMB TranX 120/160 detection loop function normally, but function as well as a beacon for the AMB DisplaylT. The AMB DisplaylT, which is usually fitted to the steering wheel of a kart, detects the signal produced by the activated detection loop while passing the loop and indicates the actual lap time on its display.

2. Installation of the activated detection loop 3 mm (1/8") '"H'" -20 A-A mm -3/4") 1. Remove the existing loop wires and connection box plus the coax cable. If the coax cable was put into a duct, use the old coax cable to pull the new coax plus 12V power cable through. 2. Put the wires of the activated detection loop in the slots, with the termination box in the spot where the 470 Ohm resistor used to be and cut the excess length of the wires. Make sure karts can not pass outside the detection loop.

of the track will not get closer than 5 m /15 ft to the detection loop, to avoid false inputs. 6. The 12V power cable may be installed alongside the coax cable leading to the AMB TranX160 decoder. The 12V adapter powering the TranX activated detection loop may be installed permanently, but must be well protected from water and humidity. 7. The activated detection loop may be powered permanently, even when the AMB TranX decoder etc. are not installed or present.

4. Operating the system I Trouble shooting Install the existing AMB TranX 160 system as usual and according to the instructions the manual. When the (new) coax cable is connected to the decoder, the TranX 160 system should operate as before. Now plug in the 12V adapter powering the activated detection loop. The background noise level may rise about 10 points, due to the (very low) noise level of the beacon operating.
