3. Conversion of km/naut/mile
1. Turn the rotating ring and see how many
kilometres or knots one mile will correspond to.
2. Set the mile ▼ (or STAT ▼ = stature mile) to the
10 mark and look at the figure lying below the
km ▼.
This is equivalent in kilometres (= 1.6).
3. The figure located under the naut ▼ (or knot ▼ =
nautical mile) is the equivalent in nauts (= 0.86).
4. Similarly, any desired distance can be converted
to km/naut/mile.
16. PRECAUTIONS FOR LONG TERM USE
1. Water Resistance
Check the chart to determine the
water resistant properties of this
watch.
Do not operate any of the buttons when the watch
is wet.
2. Avoid extreme temperatures
Avoid leaving your watch in extremely warm or
cold locations for long periods of time.
3. Avoid strong shocks
4. Avoid strong magnetic fields
5. Avoid chemicals and gases
Avoid wearing the watch in the presence of strong
chemicals or gases. If mercury or any chemical
(such as gasoline, thinner, alcohol, cosmetic
sprays or the like), comes in contact with the
watch, discolouration, deterioration or damage to
case, band or other components may occur.
6. Avoid static electricity
The integrated circuits used in this watch are
sensitive to static electricity. If exposed to intense
static electricity, the watch's display may lose its
accuracy.
• Calculation results
should only be used as
approximate indicators.
• The calculator scale
does not indicate decimal
places.
WATER RESIST may sometimes be the abbreviation
of WATER RESISTANT.
7. Keep Your Watch Clean
Any dirt left on the case or band may cause skin
rash. A watchband will easily become soiled with
dust and perspiration because it is in direct
contact with the skin. Even a stainless or gold-
plated band may begin to corrode if it has not
been cleaned for a long period of time.
8. Periodic inspection
Getting your watch checked every 2 or 3 years is
recommended to ensure long use and trouble-
free operation.
9. Be sure to keep the battery out of reach of
infants and small children:
Should accidental ingestion occur, consult a
doctor at once.
