content of the exercise prior to the competition.
5.1
The host province shall for practical reasons provide the major products
such as test equipment, computers, business equipment of consumer products.
5.2
The host province in required to provide service information and model
identification about the products to be worked upon in national competition
three months in advance of that competition.
5.3
The equipment offered for fault finding will be identified by the host
province,
3 mounts prior to the contest. The equipment provided by the host province
must be commercially available. The chief expert must approve or reject the
equipment selected by the host province within one month of the receipt of the
equipment information. The chief expert must disseminate the above-mentioned
information to all participating experts within one month of approving the
equipment provided by the host province.
5.4
The experts shall provide the remaining practical exercises and assembly
projects governing IVTO Competitors.
6.1
All equipment offered by the host province will be approved by the chief
expert three months prior to the commencement of the competition.
6.2
The following machines and equipments will be made available to each
competitor:
1
working table with partition walls and sufficient electrical sockets
for test equipment
1
magnified lamp for the working area
1
isolated supply for
the equipment under test
-
antenna connection providing good off-air signals
-
other such test equipment as may be required to assemble or service
specific test projects provided by the host province.
6.3
The competitor must bring the remaining tools and auxiliary material and
present it to the judges for inspection on the first day of competition. The
judges shall rule out any items brought to the competition that are not
considered normal electronic tools that will give any competitor an unfair
advantage.
