Please fully charge your watch before use by exposing it to
light.
When the watch does not operate according to the instruction manual, this means that it is
insufficiently charged. When this happens, charge the watch before using by exposing to
direct sunlight for at least 2 hours.
[This watch is equipped with a power save function (Power Save 1 and 2) that reduces
power consumption]
Power Save 1: When the solar cell is not being exposed to light for more than 24 hours
continuously, the second hand and the minute hand stop and the power
save state is entered.
Power Save 2: The Power Save 1 state will continue for about 2 days after which the
Power Save 2 state is entered.
* Upon entering the power save state, the second hand stops at the 12 o’clock position while
the minute hand stops at the reference position. For details concerning the power save function, please read [6. A. Power Save Function].

This watch is a radio wave watch that automatically corrects the time and date by
receiving the standard time radio wave (time information) transmitted in Germany.
In addition, this watch also functions as an analog solar-powered watch equipped
with a photoelectric power generation function that drives the watch by converting
light energy into electrical energy. It is also equipped with other useful functions,
including a power save function that reduces power consumption of the watch when
the solar cell is not exposed to light.
* Locations Where Radio Wave Reception may be Difficult
• It may be difficult to receive radio waves in certain locations. The time and
date are not set correctly if radio waves are unable to be received.
• There rarely may be times when the time and date are not set correctly even if
radio waves are received.
When this happens, carefully read the section on page 8 entitled, “Radio Wave
Receiving Function” and then try repeating the procedure for receiving radio
waves (either manually or automatically).

1. Before Using
A. Radio Wave Receiving Function
<For Good Reception>
· This watch incorporates an antenna for receiving radio waves at the 12:00 position inside the case. For good reception, it is ideal to have the 12:00 position of
the watch facing in the direction of the radio wave transmitter station.
· Try receiving radio waves using the reception level function while changing the
orientation of the watch or location. Finding the location and direction at which
radio waves can be received easily results in more reliable reception.
· To obtain stable reception, do not move the watch during reception.
· Radio waves may be hard to receive due to blockage by a metallic object or the
environment. When inside a building and so on, reception should be performed
as close to a window as possible.
Radio waves may be unable to be received in close proximity to the radio wave
transmitter station (within a distance of about 10 km). In addition, radio waves
may not be received properly even if they are able to be received. If this happens,
either change the orientation of the watch antenna to 45 degrees to 90 degrees relative to the radio wave transmitter station or move to a location farther away from
the radio wave transmitter station (more than about 10 km away), and then try
receiving radio waves again.
Antenna
10 11
<Locations where Reception may be Difficult>
It may not be possible to properly receive radio waves at the following locations
susceptible to generation of radio wave noise or under the following environment
conditions that cause difficulty in receiving radio waves.
(1) Locations subject to extremely high or low temperatures
(2) Inside a reinforced concrete building, between tall buildings or in valleys
between mountains or underground
(3) In a car, train or airplane
(4) Near high-tension wires (power lines), railroad overhead wires or airports (com-
munication facilities)
(5) Near a cellular telephone in use
(6) Near household electric appliances or OA equipment such as TV sets, refrigera-
tors, personal computers, fax machines, etc.
* Radio waves cannot be received properly while walking or traveling in a motor
vehicle, etc.
<General Reference for Receiving Areas>
A general reference for the areas where the watch can receive standard time radio
waves is as follows. However, these areas may vary depending on the time zone,
seasonal variations and weather (presence of lightning, etc.). Since this map only
provides a general reference of the standard receiving areas, it may not apply in
some particular locations even within the range shown on the map.

vicinity of Lake Leman)
B. Photoelectric Power Generation Function
This watch uses a secondary battery to store electrical energy. Once fully charged,
the watch will continue to keep the correct time for about 8 years (in the Power
Save 2 state) without further charging. Furthermore, it will continue to keep the correct time for about 9 months when the Power Save modes are not activated.
Power Save: When power generation stops as a result of the solar cell not being
expose to light, the power save function is activated to reduce the
power consumption of the watch. (For more details, please refer to
section 6-A entitled, “Power Save Function”.)
<For Optimum Use of this Watch>
In order to use this watch comfortably, try to keep the watch charged at all times.
There is no risk of overcharging no matter how often the watch is charged (overcharging protection function).
Expose the dial (solar cell) to light when charging.
14 15
<Try to Keep the Watch Charged at all Times>
· If you wear long sleeves, the fabric may cover the watch and prevent it from being
exposed to light resulting in the watch becoming insufficiently charged.
· When the watch is removed, try to place it in as bright a location as possible. This
will enable the watch to continue to run properly at all times.
2. Receiving Radio Waves
There are two ways to receive radio waves, namely automatic reception (regular
automatic reception, return automatic reception and recovery automatic reception)
and free reception. When radio waves are received properly, the time (hours, minutes, seconds, daylight savings time) and date (month, day, year) are corrected automatically.
1. Regular Automatic Reception: Radio waves are received automatically twice a
day at 3:00 AM and 4:00 AM each day.
2. Free Reception: Radio waves can be received at any time.
3. Return Automatic Reception: Radio waves are received when the watch automat-
ically returns to the reception state after the Power
Save 2 state has been canceled.
1716
4. Recovery Automatic Reception: The watch switches to the recovery automatic
reception state and receives radio waves when
the watch is sufficiently charged after having
stopped due to being insufficiently charged.
[Data Received from German Standard Time Radio Wave]
· Time information: Hours, minutes, seconds, daylight savings time
· Date information: Month, day, year
3. Setting the Time and Date by Radio Wave Reception
It is recommended to try receiving radio waves while changing the direction and
location of the watch to find the location and direction at which reception is easiest
while referring to the reception level. Do not move the watch when receiving radio
waves.
A. Radio Wave Reception (Regular Automatic Reception and
Free Reception)
(1) Reception
method
The second hand automatically
moves to the RX (reception in
progress) position (0 seconds
position) twice a day at 3:00
AM and 4:00 AM each day,
after which the watch begins to
receive radio waves.
When button (A) is pressed after about 2 seconds,
the second hand rapidly moves to the RX (reception
is progress) position (0 seconds position), after
which the watch begins to receive radio waves.
Note: If button (A) is continuously depressed for 10
seconds or more, the watch changes to the “Reference Position (0 position/12:00 position) Check”.
Regular automatic reception Free reception

If reception is successful: The time (including daylight savings time) and date are cor-
rected automatically based on the results of reception.
If reception has failed: The watch returns to the time and date display stored in the
watch prior to reception.
When button (A) is pressed after receiving, the second hand rapidly moves to the
reception result (reception level) and stops.
· The watch automatically returns to the current time after 10 seconds. In addition, the
watch can also be returned to the current time by pressing button (A).
However, if button (A) is continuously depressed for 2 seconds or more, the second
hand moves to the RX position indicating that reception is in progress and free reception begins.
Note: Reception results cannot be confirmed even if button (A) is pressed while each
hand is returning to the current time following completion of reception. Confirm reception results by pressing button (A) only after each hand has returned to
the current time.
B. Indication of Reception Level during Radio Wave Reception
During radio wave reception, the second hand waits at the reception position corresponding to the reception status and indicates the reception level (degree of ease of
radio wave reception).

E. Recovery Automatic Reception
When the watch is sufficiently recharged after having stopped as a result of being
insufficiently charged, the watch automatically performs one cycle of recovery
automatic reception.
· When reception has been successful: The time and date are corrected automatically and the watch begins to run. The watch can be used normally at this time.
· When reception has failed: The time setting warning function (irregular 2-second
interval movement) is activated. In this case, either perform free reception or set
the time and date manually.
22
D. Return Automatic Reception
When the Power Save 2 state (during which the second hand and minute hand are
stopped) is canceled, the watch automatically changes to the reception state after
rapidly returning to the time stored in memory, and begins to receive radio waves.
· When reception has been successful: The time and date are corrected automatically and the watch begins to run.
· When reception has failed: The watch returns to the time and date display stored
in memory prior to reception and begins to run.
24 25
4. Time Difference Correction Function
This watch is equipped with two types of time difference correction functions.
<Time Difference Correction Function (1)>
· The time difference can be set in 1 hour units relative to the German standard time
that has been received by the watch.
· The setting range is from –2 hours to +2 hours.
<Time Difference Correction Function (2)>
· The time difference can be set to an arbitrary time in 1 hour units by correcting
the hour hand manually.
· The time difference can be set in areas where the German standard time radio
wave is unable to be received. In the case of having received the German standard time radio wave (either by free reception or regular automatic reception)
after setting the time difference using the time difference correction function (2),
the time difference is automatically corrected to the German standard time.

B. Setting Procedure for Time Difference Correction (2)
The time difference can be corrected for 30 seconds after pressing button (A) or for
30 seconds following completion of hand movement after the crown has been
pulled out to the first position. The date also changes in coordination with the hour
hand.
(1) Pull the crown out to the first position.
· The second hand moves to the position of the “year” and “month” stored in
memory and then stops.
(2) When button (A) is pressed, the hour hand performs demonstration movement
after which the watch changes the “hour” and “date” time difference correction
state.
· The second hand rapidly returns to the current time and the watch begins to run.
(3) Turn the crown to set to the “hour” of the region for which time difference is to
be set.
① If turned to the right (by one click), the hour hand moves forward (clockwise)
by one hour.
② If turned to the left (by one click), the hour hand moves backward (counter-
clockwise) by one hour.
· Turning the crown continuously (by two clicks or more) causes the hour hand to
move continuously.
· Continuous movement can be interrupted by clicking the crown by one click to
the left or right.

Notes: · Since the hour hand moves in coordination with the minute hand, the hour
hand can be set by continuous movement of the second hand and minute
hand. In addition, the date also changes in coordination with the hour hand.
· The watch automatically advances past non-existent dates such as February
30 or April 31. While the watch is advancing, the second hand and minute
hand wait at the 12:00 position, while the hour hand moves automatically to
pass by the non-existent date.
(3) Return the crown to the normal position in synchronization with a telephone or
other time service.
34
B. Correcting the Seconds and Minutes
(1) When the crown is pulled out to the second position, the second hand rapidly
moves to the 0 seconds position and stops.
· If the second hand does not stop at the 0 seconds position, check the “Reference
Position” and perform the procedure for “Setting the Reference Position”.
(2) Turn the crown to set the minutes.
① When the crown is turned to the right (by one click), the second hand makes
one revolution while moving in the clockwise direction, and the minute hand
advances by one minute.
② When the crown is turned to the left (by one click), the second hand makes
one revolution while moving in the counter-clockwise direction, and the
minute hand moves back by one minute.
· Turning the crown continuously (by two or more clicks) causes the second hand
and minute hand to move continuously.
· Turn the crown to the left or right by one click to interrupt continuous movement
of the hands.
37
Note: When the second hand makes two revolutions continuously, it rapidly returns
to the position of the original year and month.
Examples:
Case of December in a leap year: Align the second hand at the 0 seconds position.
Case of April in the third year after the most recent leap year:
Align the second hand at the 23 seconds position (between 4:00 and 5:00).
(3) After correcting the year and month, return the crown to the normal position.
The second hand returns to the current time and the watch begins to run.
36
C. Correcting the Elapsed Years and Month
When the crown is pulled out to the first position, the second hand changes to an
indication of the number of years that have elapsed since the most recent leap year
(elapsed years) and the month.
(1) When the crown is pulled out to the first position, the second hand moves to the
year and month stored in memory and stops.
(2) Turn the crown to set the year and month.
① Turn the crown to the right (by one click) to align the second hand at the posi-
tion corresponding to the number of years that have elapsed since the most
recent leap year and the month.
② When the crown is turned to the left (by one click), the second hand moves
backwards.
· Turning the crown continuously (by two clicks or more) causes the second hand
to move continuously.
· Turn the crown to the left or right by one click to interrupt continuous movement
of the second hand.

(4) Turn the crown to set the hours.
① When the crown is turned to the right (by one click), the hour hand advances
(in the clockwise direction) by one hour.
② When the crown is turned to the left (by one click), the hour hand moves back
(in the counter-clockwise direction) by one hour.
· Turning the crown continuously (by two or more clicks) causes the hour hand to
move continuously.
· Turn the crown to the left or right by one click to interrupt continuous movement
of the hour hand.
Note: When correcting the time, set the time while paying attention to AM and PM.
The time when the date changes is AM.
(5) After correcting the time, always make sure to return the crown to the normal
position.
D. Correcting the Hours and Date
Since the date changes in coordination with the hour hand, it cannot be corrected
independently. The date is changed by continuously advancing the hour hand. The
hour hand and date can be corrected for 30 seconds after pressing button (A) or for
30 seconds after the hour hand has stopped moving.
(1) Pull the crown out to the first position.
· The second hand moves to the position of the year and month stored in memory
and stops.
(2) When button (A) is pressed once, the hour hand performs a demonstration
movement and then changes to the hour and date correction state.
· The second hand rapidly returns to the current time and begins to move
(3) Turn the crown continuously to continuously advance the hour hand and set the
date.
· The date changes between the hours of about 10:00 PM and 3:00 AM.
· In the case the month is set to a month with less than 31 days, a non-existent date
is automatically passed by and the watch indicates the first day of the following
month even if the date is changed from the 30th to the 31st.

A. Power Save Function
<Power Save 1>
The second hand stops to save power when it reaches the 0 seconds position if the solar
cell is not exposed to light and power is not generated for 24 consecutive hours.
· The minute hand stops at the position corresponding to the second hand.
· The hour hand and date change from normal movement (3-minute interval movement)
to 1- hour interval movement.
Note: Reception can still be performed either by regular automatic reception or free
reception. However, in the case of performing free reception, Power Save 1 is
canceled due to the switching operation.
<Canceling Power Save 1>
Power Save 1 is canceled either by resuming power generation by exposing the solar cell
to light, or by operating the crown or buttons.
· When Power Save 1 is canceled, the second hand and minute hand rapidly return to
the current time and begins 1-second interval movement. (When Power Save 1 is canceled by pressing button (A), the display returns to the current time after displaying
the reception results for about 10 seconds.)
· The hands move in the clockwise or counter-clockwise direction to rapidly return to
the current time.
· It takes a maximum of about 1 minute for the hands to return to the current time.
<Power Save 2>
The watch automatically switches to the Power Save 2 state to further reduce current
consumption if the Power Save 1 state continues for approximately 2 days.
· Each hand and the date continue in the Power Save 1 state.
Note: Regular automatic reception is not performed every day. In addition, free recep-
tion can also not be performed.
<Canceling Power Save 2>
Power Save 2 is canceled when power generation is resumed by exposing the solar cell
to light.
· Recovery automatic reception is performed after the second hand and minute hand
rapidly move to the current time. 1-second interval movement starts following completion of reception and the watch returns to normal operation.
· Power Save 2 cannot be canceled with the crown or buttons.
46 47
Notes:
· The watch also switches to the power save function from either 2-second interval
movement (insufficient charge warning function) or irregular 2-second interval movement (time setting warning function).
· During the time the secondary battery is fully charged and the overcharging prevention function is activated, the power save function is not activated even if power is not
generated as a result of the solar cell not being exposed to light. In addition, the
power save function is similarly not activated when the secondary battery temporarily
becomes fully charged as a result of the solar cell being exposed to intense light.
· Depending on the environment in which the watch is stored and so forth, reception may not be completed successfully even if recovery automatic reception is
performed after cancellation of Power Save 2. It is therefore recommended to
perform free reception before using the watch.
B. Insufficient Charge Warning Function
When the capacity of the secondary battery becomes low as a result of not exposing
the solar cell to light, the second hand changes to 2-second interval movement (insufficient charge warning function) to indicate that the watch is insufficiently charged.
Although the watch continues to run normally at this time, after about 11 days have
passed since the start of 2-second interval movement, the watch ends up stopping as a
result of being insufficiently charged. Sufficiently recharge the watch by exposing to
light so that the second hand returns to its original 1-second interval movement.
Notes:
· The time and date cannot be corrected manually during 2-second interval movement.
· Regular automatic and free reception are also not available. Although the
receiving station can be switched, the receiving station is not indicated.
· The all-reset procedure can be performed.
48 49
C. Time Setting Warning Function
Recovery automatic reception is performed when the watch is exposed to light and
sufficiently recharged after having stopped as a result of being insufficiently
charged.
· If reception has been successful, the time is corrected and the second hand begins
1-second interval movement.
· If reception has failed, the second hand moves by irregular 2-second interval
movement (time setting warning function) indicating that the time is incorrect.
Reset the time and date either by free reception or by manual setting.
· Irregular 2-second interval movement will continue unless the time is reset.
Note: In the case the watch has stopped as a result of being insufficiently charged, a
minimum of about 30 minutes are required until recovery automatic reception
is performed even if the watch is sufficiently exposed to light.
D. Overcharging Prevention Function
When the secondary battery becomes fully charged, the overcharging prevention
function is activated to prevent the battery from being charged further.

7. General Reference for Charging Times of Solar-Powered Watches
The time required for recharging varies according to the model of the watch (color of the
dial, etc.). The following times are shown below only to serve as a reference.
· Recharging time refers to the amount of time the watch is continuously exposed to
light.

Charging time to fully charge: Time required for recharging the watch from the
stopped state when insufficiently charged to fully
charged.
Charging time for 1 day of operation: Time required for recharging the watch to run
for 1 day.
Note:
Once fully charged, this watch will continue to run without recharging for approximately 8 years (when in the Power Save 2 state). Furthermore, it will continue to
keep the correct time for about 9 months when the Power Save modes are not activated. However, once it stops running due to being insufficiently charged, a considerable amount of time is required to recharge so that it starts running again as indicated in the table. Try to recharge the watch daily whenever possible.

8. Solar-Powered Watch Handling Precautions
<Try to Keep the Watch Charged at all Times>
· If you wear long sleeves, the fabric may cover the watch and prevent it from
being exposed to light resulting in the watch becoming insufficiently charged.
· When the watch is removed, try to place it in as bright a location as possible.
This will enable the watch to continue to run properly at all times.
CAUTION: Charging Precautions
· Avoid charging at high temperatures (over 60°C /140°F) since allowing the
watch to reach a high temperature during charging can cause a malfunction.
Examples: Charging by placing the watch too close to a light source that may
become hot such as an incandescent lamp or halogen lamp, or charging
by placing the watch on an automobile dashboard that can easily reach a
high temperature.
· When charging the watch with an incandescent lamp, always make sure to place
the watch at least 50 cm (20 in) away from the light source to prevent the watch
from reaching a high temperature.
9. Replacing the Secondary Battery
Unlike ordinary batteries, the secondary battery used in this watch does not have to
be periodically replaced since it is able to be charged and discharged repeatedly.
54 55
10. Setting the Reference Position
In the case the reference position of the watch has changed due to being subjected
to a strong shock or the effect of static electricity, check the reference position (0
position/12:00 position) that serves as the basis of operation.
If the second hand does not indicate the correct position, it is possible that the reference position may have shifted. Check the reference position of each hand using
the procedure described below.
A. Checking the Reference Position
(1) Continuously depress button (A) for at least 10 seconds with the crown in the
normal position.
· After the second hand indicates the result of the previous reception, the second
hand moves to the RX position (12:00 position) and then each hand rapidly
moves to the reference position and stops.
· The date changes in coordination with the hour hand, and stops between 31 and 1.
(2) When button (A) is pressed for about 2 seconds, the hands rapidly return to the
current time. Alternatively, the watch will automatically return to the current
time if the buttons or crown are not operated for 2 minutes or more.
Note: Set the reference position if any of the hands or date do not indicate the refer-
ence position.
B. Setting the Reference Position
(1) Continuously depress button (A) for 10
seconds or more.
· After the second hand indicates the result
of the previous reception, the second hand
moves to the RX position (12:00 position)
and then each hand rapidly moves to the
reference position and stops.
(2) Pull the crown out to the first position, set
the date between 31 and 1, and set the
hour hand to 12:00.
· Set the date by continuously turning the
crown to continuously move the hour hand.
· Turn the crown to set the hours.
(3) Pull the crown out to the second position and set the second hand and minute
hand to 12:00.
· Turn the crown to set the seconds and minutes.
57
(4) Return the crown to the normal position and press button (A) for about 2 sec-
onds.
· Each hand and the date rapidly return to the current time.
Note:
· After setting the reference position, always make sure to perform free reception
or correct the time and date manually before using the watch.

<Changing the Mode when Setting the Reference Position>
11. All-Reset
The watch display may become abnormal due to the effects of static electricity or a
strong shock. If this happens, set the reference position.
(1) Pull the crown out to the second position.
· The second hand rapidly moves to the reference position stored in memory and
stops.
(2) Press buttons (A) and (B) simultaneously.
· The second hand and hour hand perform a demonstration movement consisting
of moving forward, backward and then forward again.
This completes the all-reset procedure. Always make sure to set the reference position after performing the all-reset procedure.
Cautions Following All-Reset:
· After performing the all-reset procedure, it takes about 1 second to store the reference position in memory when the reference position has been set. Do not pull
out the crown immediately after setting the reference position.

· After performing the all-reset procedure, the second hand will remain stopped
even if the crown is returned to the normal position unless the reference position
is set with the crown at both the first and second positions.
· After performing the all-reset procedure, the time shown after setting the reference position is 12:00 AM. When setting the time manually, set both the time
and date while paying attention to AM and PM so that the time is set correctly.

• Water-resistance for daily use (to 3 atmospheres): This type of watch is waterresistant to minor exposure to water. For example, you may wear the watch while
washing your face; however, it is not designed for use underwater.
• Upgraded water-resistance for daily use (to 5 atmospheres): This type of watch is
water-resistant to moderate exposure to water. You may wear the watch while
swimming; however, it is not designed for use while skin diving.
• Upgraded water-resistance for daily use (to 10/20 atmospheres): This type of
watch may be used for skin diving; however, it is not designed for scuba or saturated diving using helium gas.
CAUTION:
• Be sure to use the watch with the crown pressed in (normal position). If your
watch has a screw-type crown or button, be sure to tighten the crown completely.
• Do NOT operate the crown or button with wet fingers or when the watch is wet.
Water may enter the watch and compromise water-resistance.
• If the watch is used in seawater, rinse with fresh water afterward and wipe with a
dry cloth.
• If moisture has entered the watch, or if the inside of the crystal is fogged up and
does not become clear within a day, immediately take the watch to your dealer or
Citizen Service Center for repair. Leaving the watch in such a state will allow corrosion to form inside.
• If seawater enters the watch, place the watch in a box or plastic bag and immediately take it in for repair. Otherwise, pressure inside the watch will increase, and
parts (crystal, crown, buttons, etc.) may come off.
CAUTION: Keep your watch clean.
• Leaving dust and dirt deposited between the case and crown may result in difficulty in pulling the crown out. Rotate the crown while in its normal position from
time to time to loosen dust and dirt and then brush it off.
• Dust and dirt tend to be deposited in gaps in the back of the case or band. Deposited dust and dirt may cause corrosion and soil your clothing. Clean the watch occasionally.
Cleaning the Watch
• Use a soft cloth to wipe off dirt, perspiration and water from the case and crystal.
• Use a soft, dry cloth to wipe off perspiration and dirt from the leather band.
• To clean a metal, plastic, or rubber watchband, wash away dirt with water. Use a
soft brush to remove dust and dirt jammed in the gaps in the metal band.
NOTE: Avoid using solvents (thinner, benzine, etc.), as they may mar the finish.
66 67
Timekeeping may become inaccurate if the watch is exposed to strong static electricity, such as is emitted from a TV screen.
• Do NOT subject the watch to a strong shock such as dropping it onto a hard floor.
• Avoid using the watch in an environment where it may be exposed to chemicals or
corrosive gases.
If solvents, such as thinner and benzine, or substances containing such solvents
come in contact with the watch, discoloration, melting, cracking, etc. may result. If
the watch comes in contact with mercury used in thermometers, the case, band or
other parts may become discolored.
Periodical inspections
Your watch requires inspection once every two or three years for safety and long
use.
To keep your watch water resistant, the packing needs to be replaced regularly.
Other parts are required to be inspected and replaced as necessary.
Ask for Citizen geuine parts during replacement.
CAUTION: Operating environment
• Use the watch within the operating temperature range specified in the instruction
manual.
Using the watch where temperatures are outside the specified range may result in
deterioration of functions or even stoppage of the watch.
• Do NOT use the watch in places where it is exposed to high temperature, such as
in a sauna.
Doing so may result in a burn.
• Do NOT leave the watch in a place where it is exposed to high temperature, such
as the glove compartment or dash-board of a car.
Doing so may result in deterioration of the watch, such as deformation of plastic
parts.
• Do NOT place the watch close to a magnet.
Timekeeping will become inaccurate if you place the watch close to magnetic
health equipment such as a magnetic necklace, a magnetic latch of a refrigerator
door,handbag clasp or the earphone of a mobile phone. If this has occurred, move
the watch away from the magnet and reset the time.
• Do NOT place the watch close to household appliances that generate static electricity.
