Citizen AS4020-44B [3/38] Set the mode hand to the tme mode

Request to customers 1

If the second hand of the watch is moving at two second intervals while the watch is in use this indicates that the watch is insufficiently charged use the watch after first recharging by referring to the section entitled 15 general reference for charging times of solar powered watches since it may be difficult for light to shine on the watch as a result of being covered by clothing during the winter months in particular it is recommended to charge the watch by exposing to direct sunlight once a month to ensure that your watch is used comfortably it is recommended to try to keep the watch fully charged at all times 2

This radio wave watch is equipped with a regular automatic reception function that sets the time and date by automatically receiving radio waves at 3 00 am or 4 00 am and a free reception function that allows the time to be set arbitrarily at any time by receiving radio waves this watch is unable to receive radio waves of countries other than germany 2

W please use this watch after charging sufficiently by placing in light w 2

W this watch is a radio wave watch that receives the standard time radio wave transmitted in germany w 2

Please confirm the following before using the watch 3

Set the mode hand to the tme mode 3

The mode can be switched by pulling the crown out to position 1 set the mode hand to one of the three locations of the tme mode return the crown to its original position after switching the mode 3

W please confirm the following before using the watch w 3

Free reception the free reception function lets you receive radio waves at any time use this function when the reception environment has changed or in other cases when radio waves are unable to be received by regular automatic reception do not move the watch during free reception to ensure that radio waves are reliably received it may take up to about 15 minutes to receive radio waves 4

Important points regarding radio wave reception 4

Radio waves are received in the time mode tme 3 locations or local time mode l tm radio waves cannot be received in other modes 4

Regular automatic reception the watch sets the time including daylight savings time and date by automatically receiving radio waves at 3 00 am or 4 00 am each day radio waves are not received at 4 00 am if they have been successfully received at 3 00 am 4

Free reception 10

Free reception can be used to receive radio waves at any time 1 when receiving radio waves remove the watch from your wrist and place it in a stable location where radio waves can be received easily such as by a window with the 6 00 position of the watch facing in the direction of the radio wave transmitter station 2 press button b at the 4 00 position for about 2 seconds or more after the hearing the confirmatory tone release your finger after checking that the second hand has moved to the standby position rx 12 00 the remainder of the procedure is the same as steps 2 and 3 of the procedure for regular automatic reception on the previous page 10

If reception is successful a beeping tone sounds twice and the watch is corrected to the correct time if reception has failed a beeping tone sounds once and the watch returns to the time display prior to radio wave reception 10

Movement of second hand from start of reception to completion 10

Reception standby reception in progress completion of reception 10

Recovery automatic reception 10

The second hand moves to either the h m or l reception level although the second hand may turn to correct the time during reception this does not mean that reception is completed 10

The second hand moves to the rx position and stops 10

When the watch has stopped as a result of being insufficiently charged radio waves are then received once automatically however charge the watch for about 30 minutes under direct sunlight to initiate recovery automatic reception try to keep the watch charged at all times so that it does not become insufficiently charged 10

B confirmation of reception result 11

C reception level and reception result 11

During the time radio waves are being received the second hand waits at the reception position corresponding to the reception state to indicate the reception level following reception the reception result can be confirmed by pressing button b 11

When button b is pressed once the second hand moves to h m l or no to enable confirmation of the reception result note since the second hand moves to the 12 00 rx position and free reception begins if button b is depressed continuously for 2 seconds or more do not press button b for 2 seconds or more in the case of having mistakenly begun free reception press button b for 2 seconds and to cancel radio wave reception the reception is indicated for 10 seconds after which the watch automatically returns to the current time in addition the watch can also be returned to the current time by pressing button b while the reception result is indicated 11

Although the standard time radio waves used by radio wave watches are transmitted nearly continuously 24 hours a day transmission may be interrupted for reasons such as maintenance and inspections this watch will continue to keep the correct time at an accuracy of within 15 seconds per month even if it is unable to receive standard time radio waves 12

D general reference for receiving areas 12

The following provides a general reference for those areas where the watch is able to receive standard time radio waves these areas may vary as a result of changes in radio rave reception conditions depending on the time period seasonal variations and weather since this map only provides a general reference of the areas where radio waves can be received there may be locations where radio waves cannot be received even if they are within the range shown on the map 12

General reference for charging times of solar powered watches 31

Note during two second interval movement 1 the time cannot be corrected by regular automatic or free reception and the time cannot be corrected manually 2 only the time mode is displayed and other modes cannot be used 31

The time required for charging varies according to the model of the watch color of the dial etc the following times are shown below to serve only as a reference charging time refers to the amount of time the watch is continuously exposed to light 31

When the secondary battery becomes fully charged by exposing the solar cell to light the overcharging prevention function is activated automatically to prevent the battery from being charged further there is no effect on the secondary battery timekeeping accuracy watch functions or performance no matter how much the watch is charged 31
