2. INTRODUCTION

2.1 Overview

The SEIKO Sports Printer CT-2000 is a multi-purpose printer/timer that can be used for various
sports events requiring timing such as track and road running races, swimming, ski and skate.

2.2 Features

z Being equipped with various measurement modes, CT-2000 can be used for timing of all types

of sports events.

z Timing down to 1/1,000 of a second is possible.

The method of calculating the fraction of a second can be selected from 10 types including
rounding up, rounding down and rounding off, thus making it possible to comply with various
timing rules adopted in different sports events.

z A large-sized LCD monitor is used to make it easier to check various types of information

displayed on it. (20 characters x 4 lines)

z The design of the grip switch is renewed so that it better fits into your palm and provides easier

switch operation.

z By using resin case, high durability has been achieved.

z If the dry batteries are installed when CT-2000 is powered by AC adapter, the power source

can be quickly switched over to the batteries in case of failure of AC power supply, to ensure
constant operation. *1

z Two sets of dry batteries (6 AA size cells per set) can be installed in the main body, and the

power source is switched over automatically between them. By replacing the unused set of dry
batteries with new ones, CT-2000 can be powered by the dry batteries continuously for a long
time.*1

z Rechargeable batteries can be used in place of alkaline dry batteries.*1
z CT-2000 can also be powered by external battery (DC11V～DC14V)*1

z The Auto Measurement Mode enables the measurement during individual practices performed

alone.
・ Reaction time (start reaction time: time after the start signal until swimmer’s feet have left the

starting block), lap time, and split time can be measured during swimming practices.

・ Lap time and split time can be measured during practices of speed skating, track, and other

races.*2

・ By outputting a signal to an external buzzer device, CT-2000 can control the device to

generate a starting sound automatically.*2

z Even if the actual start time has differed from the scheduled time, the Time Correction Mode

(inputting time difference from start time) corrects the scheduled start time set in advance in the
secondary CT-2000 units, enabling them to synchronize with the master CT-2000 unit.

z The Speed Measurement Mode measures the average speed over a given section of the entire

distance.*2

z By connecting a Bib No. input device with CT-2000, the measured times can be printed out

together with the Bib No.*2

z CT-2000 can be connected with a personal computer via USB interface.

z Two types of time signals (RS-422) are output to the scoreboard (with or without running time

data).

z A synchronization signal can be output to external devices.

z As CT-2000 is compatible with CT-1000, the grip switches, extension unit, synchronization

cables, and cables to connect with scoreboard used previously with CT-1000 can also be used
with CT-2000 (with the exception of a cable used to connect with a personal computer).

*1: Dry batteries, rechargeable batteries and external battery are not included with CT-2000, and

they should be purchased separately if required.

*2: Optional device is required.

2.3 Lap Time and Split Time

Lap time: Time required to go a given section of the

entire distance.

Split time: Time required to go from the start to any

given point of the entire distance.

2.5 How to Open the Case

Place the case with the side attached with a sticker
facing toward you, and unlock the four locks on the
upper and lower sides and two locks on the side
faces to open the case.

2.6 Power Supply

z CT-2000 can be supplied with the power from two sources. One is the power source connected

to @@@@@ (AC adapter or external battery), and the other is either of the two sets of dry
batteries.

z For external battery, use 11~14 V DC battery only.

z Rechargeable batteries can be used in place of alkaline dry batteries.

z When all types of power sources are available, the one connected to @@@@@ will be used.

z When CT-2000 is powered by the dry batteries, the LED lamp above the battery compartment

of the batteries in use lights up.

z When replacing the dry batteries with new ones, be sure to replace those in the battery

compartment whose LED lamp stays out.

z When the battery power of both sets of dry batteries has reduced to a low level, both sets are

used at the same time.
In that case, the LEDs of both battery compartments light up. Replace the batteries with new
ones set by set.

CAUTION

Install the dry batteries properly, checking that their (+) and (-)
terminals are properly aligned. A malfunction or failure may
result.

Do not use dry batteries of different types together. Otherwise,
heat generation or electrolyte leakage of the batteries may result
and cause damage to the Product.

Do not use old and new dry batteries together. Otherwise, heat
generation or electrolyte leakage of the batteries may result and
cause damage to the Product.

Use only dry batteries of the same make, type and size.
Otherwise, heat generation or electrolyte leakage of the
batteries may result and cause damage to the Product.

Use the dry batteries only within their specified operational
temperature range. The alkaline dry batteries, in particular,
should never be used in cold temperatures below the specified
range. Otherwise, they may not perform as specified, and a
malfunction of the Product may result.

If you decide not to use the Product for a long time, take out the
dry batteries. Otherwise, heat generation or electrolyte leakage
of the batteries may result and cause damage to the Product.

When an external battery is used, use 11~14 V DC battery only.
