How water proof is my watch?

Water Resistant 30m/50m/100m/200m are common marks put on watches to indicate how well a watch is sealed against water intrusion. The meter value does not relate to a diving depth as commonly believed, but to the air pressure that a sample of newly manufactured watches was exposed to in the course of a standard leakage test (ISO 2281).  An indication of the test pressure in terms of water depth does not mean a water resistant watch was designed for repeated long term use in such water depths.  A 30m water resistant watch can’t be expected to withstand long periods in a swimming pool, or to continue to function at 30 meters under water. This is because the test is conducted only once using static pressure – it doesn’t take into account the rapid or repeated changes in pressure that occur with swimming or diving, sudden temperature changes, or the age of the watch.

So, how can you select a watch that is best suited to your activites?  Here are some helpful definitions of water resistance classifications for non-diving watches as they relate to ISO 2281:

NO DECLARATION:  This model is NOT water resistant. Any water contact should be avoided.

WATER RESISTANT  This model is resistant to minor and accidental splashes. Greater water contact should be avoided

WATER RESISTANT 30m (3 ATM / 100 Feet):  Suitable for everyday use. Splash/rain resistant. NOT suitable for swimming, snorkeling, water related work and fishing. NOT suitable for diving.
WATER RESISTANT 50m (5 ATM / 160 Feet):  Suitable for swimming & white water rafting. NOT suitable for snorkeling, water related work and fishing. NOT suitable for diving.
WATER RESISTANT 100m (10 ATM / 300 Feet):  Suitable for recreational surfing, swimming, snorkeling, sailing
and water sports. Not suitable for water related work and fishing.  NOT suitable for diving.
WATER RESISTANT 200m (20 ATM / 650 Feet):  Suitable for professional marine activity and serious surface water
sports. NOT suitable for diving. 

What is the average battery life for a Traileader 1 or Traileader Jet?

Average battery life is 1-3 years. This is based on using the EL Backlight for 9 seconds per day, and the Alarm going off for 30 seconds each day.

What is the average battery life for a Traileader Pro?

Average battery life is 1 year. This is based on using the EL Backlight for 9 seconds per day, the Alarm for 30 seconds each day and use of the Pedometer and HRM for 30 minutes per day.

What might cause my HRM chest strap battery to drain quicker than it should?

Sweat and residue in the elastic band is able to conduct a weak electric current. This may turn on the chest strap electronic. We recommend that you wash the strap and elastic band completely (with soap is even better) after each workout and let it dry before storage. Store the chest strap and elastic band separately.

What computer software is the Traileader Pro compatible with?

Windows 98 / 2000 / ME / XP / Vista / 7

Where can I find what the magnetic declination is for a place in the U.S.?

Visit the NOAA website at: http://www.ngdc.noaa.gov/geomagmodels/Declination.jsp

Can I reset my Tech4o watch to factory defaults?

Yes. Holding all 4 buttons down for 3-5 seconds restarts your watch. NOTE: THIS ACTION ERASES ALL USER SETTINGS & LOGS!

What is ‘sleep mode’?

Sleep mode or power saving mode conserves the battery life of your watch when not in use. Most Tech4o watches have this feature. To put your watch to sleep, hold the LAP/RESET button for 5 seconds from the home time display. Press any button to exit the power save mode and turn the watch on. TIP: Our watches are shipped in sleep mode.

What material is used for Tech4o watch bands?

Watch bands are durable polyurethane, abbreviated PU.

What material is used for Tech4o case backs?

Our metal case backs are stainless steel. The Traileader series has plastic case backs.

My Traileader temperature reading isn’t accurate. Why?


This is a common issue with all watch thermometers, as measurements can be skewed by body heat.  The accuracy of the temperature sensor is +/- 1° at 20°C (68°F). Maximum error is +/- 2° over the whole temperature range -10° to +60° (14°F-140°).  In order to have an accurate reading of air temperature, a user must remove the watch from the wrist (for 20 - 30 minutes) so there is no body temperature effect on the sensor.

How do I pair the HRM chest strap with my Tech4o watch?

Traileader Pro - In normal time mode, hold "Mode" button -> Select "System" -> Select "Pair". The chest strap must be worn on the chest or press the two contacts with your fingertips (i.e. heart rate signal is sampling) during pairing.
Accelerator Pulse
– The slower transmission speed allows the Accelerator Pulse to pair automatically.
Heartbeat
– In normal time mode, hold “Set” button for 2 seconds.  If the Language, Clock, and Date have been set previously, press the “Mode” button to confirm those settings and to > Select “Pair”.  When ‘Pair’ appears, press the “Dual” and “St.Stp” buttons to start the pairing then place your fingertips on the chest strap contacts.  When “DONE” shows in the window, confirm by pressing the “Mode” button, then press the “Set” button to return to Time Mode.

Tips for using watches with HRM (heart rate monitor) chest straps

  • There are two contacts located on the back of the chest transmission unit. These two contacts must make firm contact with the user’s skin during measurement.
  • DO NOT take heart rate measurement when diving or under water.
  • Clean the contacts occasionally by applying a few drops of water, and wipe them dry with a paper towel to remove any residual grease.
  • DO NOT use hand cream or body lotions; it will insulate the signal between the skin and the contacts.
  • Clean your skin with soap and water for a better signal transmission.
  • If you have extremely dry skin, apply some conductive gel or water to increase conductivity.
  • Adjust the elastic chest band until it holds firmly on your chest and to avoid loosening when exercising.
  • Avoid awkward motion during measurement; it will create an inaccurate heart rate reading.
