Operation Guide 3070

• The watch receives the calibration signal for two to seven minutes everyday
when the time in the Timekeeping Mode reaches each of the calibration
times. Do not perform any button operation within seven minutes before or
after any one of the calibration times. Doing so can interfere with correct
calibration.
• Remember that reception of the calibration signal depends on the current
time in the Timekeeping Mode. The receive operation will be performed
whenever the display shows any one of the calibration times, regardless of
whether or not the displayed time actually is the correct time.
About the Receiving Indicator
The receiving indicator shows the strength of the calibration signal being
received. For best reception, be sure to keep the watch in a location where
signal strength is strongest. The receiving indicator is displayed while an auto
or manual receive operation is in progress.
• Even in an area where signal strength is strong, it takes about 10 seconds
for signal reception to stabilize enough for the receiving indicator to indicate
signal strength.

• Use the receiving indicator as a guide for checking signal strength and for
finding the best location for the watch during signal receive operations.
• Following reception of the time calibration signal and calibration of the
watch’s time setting, the Level 5 receiving indicator will remain on the
display in all modes. The Level 5 receiving indicator will not be displayed if
signal reception was unsuccessful or after you adjust the current time
setting manually.
• The Level 5 receiving indicator is displayed only when the watch is able to
receive both time and date data successfully. It does not appear when only
time data is received.
• The Level 5 receiving indicator indicates that at least one of the auto
calibration signal receive operations was successful. Note, however, that
the Level 5 receiving indicator disappears from the display each day when
the first auto receive operation of the day is performed.
To perform manual receive
1. Enter the Receive Mode.
2. Place the watch on a stable surface so its 12
o’clock side is facing towards a window.
3. Hold down A for about two seconds until
RC
starts to flash on the display.
• Time calibration signal reception takes from
two to seven minutes. Take care that you do not
perform any button operations or move the
watch during this time.
• If the receive operation is successful, the
reception date and time appear on the display,
along with the
GET indicator.
The watch will enter the Receive Mode if you
press A or if you do not perform any button
operation for about one or two minutes.

Digital Compass
A built-in bearing sensor detects magnetic north and indicates one of 16
directions on the display. Direction readings are performed in the Digital
Compass Mode.
You can store a direction reading in Bearing Memory and display that reading
as you take subsequent readings.
• For more information about Bearing Memory, see “Bearing Memory”.
• You can calibrate the bearing sensor if you suspect the direction reading is
incorrect.
• See “Using the Digital Compass While Mountain Climbing or Hiking” for
some real-life examples of how to use this feature.
