• INSTRUCTION MANUAL

CTZ-B6771

Thank you very much for purchasing a CITIZEN

QUARTZ WATCH. To ensure correct use, please

read these instructions carefully. Please ensure that

the Citizen international guarantee card is supplied

with watch on purchase, that you may claim the

guarantee service (subject to the terms of guarantee).

Precautions for use

This watch is not a measuring instrument authorised

by official authorites.Do not use the altimetry function

to judge situation involving danger.The following

precautions should be adequately understood before

using the altimeter. Please remember that the

altimetry function should be used only as general

reference.

1. Do not use the Altimetry Function When…

The altimetry should not be used in the following

situations:

• When judging your actions or situation involving

danger in an environment where the temperature

changes drastically.

• In an environment where pressure is subject to

change, such as in an airplane or building (correct

measurement cannot be obtained).

• When the altitude changes greatly within a short time.

• In case of special handling other than normal use,

not described in this manual.

2. Altimetry Function

The altitude displayed by this watch is relative to

altitude based on the sensored air pressure and “The

international standard atmospheric pressure and

altitude”. Therefore, display of measured altitude

will change if air pressure changes, even if

measurement is made in the same place. the time

display from measurement to display of altitude is

approximately 5 seconds (in continuosly altimetry

mode). Therefore, this altimetry function may not be

used in sports as skydiving, etc., where altitude

changes greatly within a short time. After 30 minutes,

Continuous Altimetry Mode will automatically change

to Altimetry Mode in which every measurement is

made every hour. To resume Continuous Altimetry

Mode, operate the watch as explained in the instruction

manual. In order to efficiently use the altimetry function

of this watch, the altitude must always be corrected

for your location, clearly indicated with the altitude.

3. Pressure Sensor

Do not disassemble the pressure sensor used in this

watch or poke it with a thin rod. Take care that no

dust enters the pressure sensor.

4. Battery

Battery life will maintain accuracy for about 2 years

under normal conditions after installing a new battery.

However, the battery life will change depending on the

frequency that the altimetry, chronograph are used.

Thus, early replacement of the battery is

recommended.

A. Basic Functions of the Altimeter

This watch is designed to calculate altitude from

changes in air pressure by using the relationship

between air pressure and altitude, based on the

conditions for standard correct atmosphere*

speciﬁed by the International Civil Aviation

Organisation (ICAO). To obtain correct altitude on the

watch, altitude must be aligned with an accurate point

(triangulation station or benchmark). Such operation

is called “Compensating the altitude” (see page 12)

* Standard atmosphere: ICAO Standard Atmosphere

adopted by the ICAO in 1964, whereby 1013.25 hPa

at 15°C is speciﬁed as elevation 0. However, air

pressure continuosly changes at any given place.

This watch’s operating is based on ISA standards.

The following chart provides an outline of ISA

standard conﬁgurations.
