4. Precautions for DataTransmission Mode
(1) Beforestartingdatatransmission,makesure that allthe connections are correctlymade.
(21 During datatransmission,avoid touching the buttons or cables which may cause a mis-
transmission or. erase data.
(3) There aretwo transfer speeds — High(H), which transfers the information in 10 seconds,
andLow(L) with a transferspeed of80 seconds. One push of button A inthe Time
Display Mode will change the display to "DATA IN (H)"; one more pushchanges itto
"DATA IN (L)". Both the reception and transmission should besetatthe samespeed.

Datainput erases previousdata
As soon as datatransferstarts, the previousdata is erased asthenew data is input. Also, if
datatransferfails,previousdata is erased. If displayreverts tothe Time DisplayMode while
in "DATA IN (H)" mode, data will notbe erased.
* Beforeswitching to "DATA OUT (H)" mode, make sure that allthe necessary connections
have been completed.
*Allthe data will be erased when the battery is exhausted.

TakeProperCare of Your RC-4000/4400
1) Water/Perspiration
Your RC-4400 isnot water resistant; care should be taken notto expose itto water or
heavy perspiration. Ifit becomes wet wipe it completely with a dry cloth.
Donot operate anyofthe buttonswhen the watch is wet.
The crystal may becomefogged ifthe outsidetemperature is lowerthanthatinside the
RC-4000/4400. A temporaryfoggingwill not cause a malfunction, butifit does not
clear, consultyour dealer.
2) Temperature
Your RC-4000/4400 is preadjusted to functionaccuratelywhenworn onthe wrist ata
normaltemperature range (14°F to 140°F or -10°C to +60°C).
Extremely high temperatures
Care should be taken notto expose yourwatch to hightemperatures (over 140°F or
60° C).
Keep it away from directsunlight orhot locations. If left in excessive heat:
•The digitaldisplay may becomeblack, but this condition will disappear without after-
effects when the temperaturereturns to normal.
*The batterylife maybe shortened, andthe battery may sufferelectrolyte leakage.
Extremely low temperatures
The watch will workaccurately down to14°F (-10°C), butdonot leave itina coldplace.
If exposed to excessive cold fora longtime:
28
*A small amount of time loss/gain may occur.
"The display may change moreslowly.
The watch will, however,return to normalwhen the temperature rises.
3) Shocks
Be careful notto drop the RC-4000/4400 or slam it against a hard surface.
4) Battery
Your RC-4000/4400 uses one SB-T12 (BR2325) lithium battery. A new battery will
serve for about two years. This two-yearbatterylifetime is calculated onthe basis ofthe
followingconditions.
* Buttonoperations — maximum of20 times a day
* Useof alarm — maximum of3 times a day,beeping for20 seconds
Note: Letting the battery run down or replacing the battery will destroy all data
stored inthe RC-4000/4400. The RC-4000/4400 isnot equippedwith a run-down
battery warning (BLD)capability.
For replacing battery, consult your dealer.
