Caution and safety precautions
Never use any other charger than the supplied or a type approved by Swiss Timing. This could
destroy the battery, cause damage to unit, and possible cause personal injury due to fire or/and
electrical shock.
Never bypass a power cord ground lead by breaking off the ground pin, or by using inappropriate
extension cords or adapters.
Never plug a power cord into the AC power source until you have made sure that all installation,
cabling and power levels, are proper, and that the applicable procedures in this manual have been
followed.
Protect the equipment against splashing, rain and excessive sun rays.
Never use the device if it is damaged or insecure.
Verify the selection of the power distribution.
Verify that the voltage quoted on the rating plate is the same as your voltage. Connect the appliance
only to power sockets with protective earth. The use of incorrect connection voids warranty.
This program may be modified at any time without prior notification.
Do not open the case; there is nothing that needs servicing inside it. Nevertheless, if the case must
be opened, you must call for some qualified personnel. The power supply cable must be
disconnected before opening the case.
During the transport of all Swiss Timing equipment delivered with a reusable carry case, the said
case should be used at all times. This is imperative to limit the damage, such as shocks or vibration
that can be caused to the units during transport.
The same cases should also be used when returning equipment to Swiss Timing for repair. Swiss
Timing reserves the right to refuse all guarantees if this condition is not fulfilled.
If the installation includes a horn, be sure to maintain a sufficient security distance from the public.

7 SUMMARY OF IAAF RULES
This is a summary of IAAF rules for concentration time in athletics. It refers to the "IAAF
Competition Rules 2004 – 2005" handbook. Please check on the http://www.iaaf.org web-site for
rules change.
Rule 180.17:
An athlete in a field event who unreasonably delays making a trial, renders himself liable to
have that trial disallowed and recorded as a failure. It is a matter for the Referee to decide,
having regard to all the circumstances, what is an unreasonable delay.
The official responsible shall indicate to an athlete that all is ready for the trial to begin, and
the period allowed for this trial shall commence from that moment. If an athlete subsequently
decides not to attempt a trial, it shall be considered a failure once that period allowed for the
trial has elapsed.
For the Pole Vault, the time shall begin when the uprights have been adjusted according to
the previous wishes of the athlete. No additional time will be allowed for further adjustment.
If the time allowed elapses once an athlete has started his trial, that trial should not be
disallowed.
The following times should not normally be exceeded:
Individual Event
Number of athletes left in
the competition
High Jump
Pole Vault
Other
More than 3 1min 1min 1min
2 or 3 1.5min 2min 1min
1 3min 5min -
Consecutive trials 2min 3min 2min
Combined Events

Consecutive trials 2min 3min 2min
* When there is only one athlete left, the mentioned times will be followed in the first trial
only if the previous trial was made by the same athlete.
Note: a clock which shows the remaining time allowed should be visible to an athlete. In
addition, an official shall raise and keep raised a yellow flag, or otherwise indicate,
for the final 15 seconds remaining of the time allowed.
