How do I set the High hr and the low hr by the chart?

I can't find much on the watch. Sweda is one company, and Lifeline is another.

Look inside the watch and look for an engraved number near the battery socket. If nothing there, a local jeweler will have a battery that fits the space. Voltage is 1.55 volts, silver oxide are best.

depends on your use of watches and the environment you tend to be in. If you are somewhere that allows you to see whether there it is day or night, than using 12 hr setting will work just fine. However if you're in a place that keeps you secluded and you are not able to determine whether it is day or night than 24 hr. setting will help you keep track of not just the time, but whether it is day or night.

Was this problem answered? If yes, can somebody tell me how. My Casio LA670W is in 24hr format and I want it back on 12hr format. My watch have 3 buttons only. Mode, Start-Stop and Timer

kc 3982 Hold the top right button, then push once the bottom left button. That should do the trick.....I just got the same watch, Do you know how to change the time?

You should carefully read the manual on this watch. It is a very sophisticated instrument realitive to its cost.

The barometric pressure in the CAL mode is set to the reference sea level. The pressure that is read in the other areas is the actual or relative pressure at your location.

There are some tollerences for the accuracy of these watches. What they are excellent at is seeing the relative differences or changes. I found that when I set the reference barometric pressure (Sea Level Pressure), everything falls in to place. I found the WP4 to be accurate to within about 15 to 20 feet accuracy for altitude most of the time. It is important to periodically check the barometric pressure from the weather office if you want it to be as accurate as possible.

When hiking or out trecking, it is advisable to check the watch's altitude relative to the map that you are using, or to a known reference. Then as you travel you can check for the altitude change.

Take care that this type of watch is to be used as a quick or easy reference only. It is not certified to be used in situations where life and safety are fully dependent on the readings from this type of watch. It is a precision instrument, but not as precise as the high end professional certified types. It is best to refer to proper maps (charts), and depend on a certified mechanical compass for absolute reference.

For Sportline 915 all you have to do to turn on the heart rate feature is to press the reset button on the lowe right and put your finger on the meatl part. A heart will appear on the top right of the screen indicating that the feature is on.

Press and hold the SET button (it will read CHIME with a flashing on or off). Then push the MODE button - the top will be flashing 12-HR or 24-HR. Push the ST/SP button to toggle between the 12-HR to 24-HR reading. Push the MODE button to get to the hour/minute/second/year/mo-day/month/day value you want to change. Push the ST/SP button to increase the value, the RESET button to reduce the value.

Heart rates are known by the garmin software as zones, numeroted 1 up to 9.
You can set on the software your heart rate, based on :
- HR max ;
- intermediate HR, linked to the zones.
Then, when you upload a session in the software, you will analyze the zones you ran in.

Another tip : to set on the Garmin itself, the Zones to ON,then Z0 to ON, and Z0 HRM to ON : here you can indicate your HRM low (ex : 165 for me) and the HRM High (185 for example). Then during your session, an up or down arrow will appear, indicate if you run below your HRM low (aerobic zone), your anaerobic zone (betwin HRM Low and High) or in VO2 max.

Hoping that's clear and that can help you.
