1 SAFETY PRECAUTIONS

The following precautions must be strictly observed for the safety of yourself and your fellow workers and for the protection of property from loss and damages.

WARNING

Emergencies

Immediately turn off the POWER switch if you detect abnormalities of the sports timer, such as fuming and burning odors. These abnormal conditions may develop into serious accidents such as fatal electric shock, and fire if left uncorrected. Refer inspection and repair services to your SEIKO dealer or agent.

Foreign metal pieces

Never put pins, wires, metal pieces or any other foreign objects into a hole or slit in the instrument on purpose or otherwise. If a foreign object is allowed into a hole or slit by mistake, turn off the POWER switch immediately, and call your SEIKO dealer for help. Failure to follow this instruction may lead to a risk of electric shock or fire. Inspection and servicing should be left to the care of your SEIKO agent or dealer.

Disassembly, repair or modification

Tampering or unauthorized repair or modification of components may adversely affect safety or performance of this instrument. Failure to follow this instruction may lead to a risk of electric shock or fire. Inspection and repair should be left to the care of your SEIKO agent or dealer.

Installation

Never leave the sports timer outdoors or in a place prone to be exposed to water. Electric leakage may possibly lead to fatal electric shock or fire accident

Mount the instrument firmly on a sturdy, level place in a manner that it will not fall over under the influence of wind, vibration or shock. Failure to observe this precaution may result in injury to personnel or damage to the instrument.

When installing the sports timer using the stand (ST-20) or car roof rack attachment (ST-21), firmly tighten up the fastening screws. If precariously installed, the instrument may yield and fall under wind pressure, vibration or shock, causing serious injury to personnel or damage to the instrument.

When the sports timer is mounted on the stand (ST-20), never use it when the wind is blowing at a velocity of 15m/s or more. Failure to observe this precaution may cause fatal accident and property damage.

When the sports timer is mounted on the car roof rack using the attachment (ST-21), limit the car speed to less than 30km/h. Failure to observe this precaution may cause fatal accident and property damage due to fall of the instrument.

When installing the team name display unit (ST-24), be sure to engage the round bars into the mating holes and tighten up the thumb nuts firmly.

Failure to observe this precaution may cause serious injury to personnel due to fall of the display unit under the influence of wind, vibration or shock.

I-5039

5

Cabling

CAUTION

Handle the cable with care. Never damage or given undue stress to the cable. Nicking the cable sheath, placing heavy objects upon the cable, or straining the cable by undue bending is most prohibitive. Failure to observe this precaution may lead to fatal electric shock or fire accident.

Do not use any cable other than specified for exclusive use with the instrument. Failure to observe this precaution may cause cable burnout or instrument failure.

Never handle the cable connector with wet hands as such operation can result in fatal electric shock.

Be sure to turn off the POWER switch in advance when plugging and unplugging the cable, except in case the sports timer is connected to

CT-1000/916 for external synchronization mode operation.

STRICTLY OBSERVE THE FOLLOWING PRECAUTIONS.

FAILURE TO OBSERVE THESE PRECAUTIONS MAY LEAD TO EXPLOSION, ELECTROLYTE

LEAKAGE, AND EXOTHERMIC REACTION OF DRY CELL, CAUSING INJURIES AND

ENVIRONMENTAL POLLUTION.

Never use any power supply other than “AA” alkali dry cell (LR6) or manganese dry cell (R6PU).

Do not use different types of dry cells together.

Handling of dry cell

Do not use old and new dry cells together. When loading the instrument with dry cells for the first time or when replacing spent dry cells, be sure to use a battery of new dry cells.

When setting the dry cells into the instrument, do not mistake their plus and negative poles for each other. Place them in the battery hatch oriented as instructed. If the dry cells are set in the wrong directions, instrument failure and other troubles may result.

After use, be sure to remove the dry cells from the instrument. If the dry cells are left inside for a long period of time, electrolyte may leak to damage the internal components of the instrument.

MODEL -306 can also be used for the display of game points and deuce points in tennis.

(4) As a downcount timer, MODEL ST-306 can downcount time to show the remaining time in basketball and other games.

(5) The following three maximum time ranges are available which can be changed over from each other to cover a wide range of sports events:

b)

(Note: The fractions of a second are not displayed during counting.)

(6) The MODEL ST-306 can measure lap time, split time and finish time. In addition, it can memorize and re-display either lap or split times for a maximum of 25 athletes . (Ex.: MODEL ST-306 can memorize and display the order of arrivals and finish times for 1st to 25th places.)

(7) The upcount function is available in two modes: one in which the time is counted up from zero, and the other in which the time is counted up from a preset time.

(8) The downcount function has a crossover counting mode in which the time is downcounted from a preset time to zero and in succession upcounted from zero. This mode is suitable for marathon and the like.

(9) The MODEL ST-306 has an auto repeat function in which the time is upcounted and downcounted at fixed intervals to sound a buzzer at a preset time. Accordingly, MODEL ST-306 can be used as a pace-clock ..

(10) The MODELST-306 is battery-powered, and can be used both indoors and outdoors. (Note, however, that it cannot be installed outdoors permanently.)

(11) The MODEL ST-306 can be used in combination with a wide variety of SEIKO sports equipment.

When connecting external equipment to the MODEL ST-306, connect the cable first, set the

FUNCTION switch to meet the external equipment connected, and then turn ON the MODEL

ST-306 and external equipment.

(d) Display data

The running time is displayed at all times.

When a player has reached the finish line, the sports timer will display finish time for about 5 seconds and then return to the running time display mode.

When other players have arrived the finish line during said 5-second period, their finish times will not be displayed.

The display pattern is determined by the RANGE settings of CT-1000/916 and ST-306 as follows.

CT-1000/916, except that the timing accuracy of the three ST-306s is governed by their respective internal clocks.

CT-1000/916 is running continuously.

After making sure that the first

ST-306 has been synchronized with CT-1000/916, disconnect the synchronization cable from the first ST-306, and connect it to the second ST-306. After making sure that the second

ST-306 has been synchronized with CT-1000/916, disconnect the cable from the second

ST-306 and connect it to the third ST-306. After making sure that the third ST-306 has been synchronized with

CT-1000/916, disconnect the cable.

（c） Operation

While being connected with CT-1000/916, ST-306 always displays time data from CT-1000/916.

Once synchronized with CT-1000/916, ST-306 maintains the accuracy by its internal clock.

Accordingly, two or more units of ST-306 can be synchronized conveniently using a single unit of

CT-1000/916.

NOTE: Use ST-306s with their DISPLAY switches at the position of ON. (If the DISPLAY switch is set to AUTO, the display will be turned off when the cable is disconnected.)

NOTE: When operating ST-306 in the external synchronization mode, do not turn off the POWER switch of ST-306 when disconnecting the synchronization cable.
