Suunto Spartan Sport Wrist HR
By default, the backlight is in automatic mode. You can change the backlight mode as well as
the backlight brightness from the settings under General » Backlight.
NOTE: Backlight brightness affects battery life. The brighter the backlight is, the quicker
the battery drains.
Standby backlight
When you are not actively using the watch by touching the screen or pressing buttons, the
watch goes into a standby mode after one minute. The display is on, but in some low-light
conditions, the screen might not be easily readable.
To improve readability in low-light conditions, you can use the standby backlight. This is a low-
brightness backlight that is on all the time.
You can toggle the standby backlight on or off from the settings under General » Backlight »
Standby.
Even though the standby backlight brightness is quite low, it decreases overall battery life
because it is on all the time.
3.6. Button and screen lock
While recording an exercise you can lock both the buttons and screen by keeping the lower
right button pressed. Once locked, you cannot change the display views, but you can turn on
the backlight with any button press if the backlight is in automatic mode.
To unlock everything, keep the lower right button pressed again.
When you are not recording an exercise, the screen locks and dims after one minute of
inactivity. To activate the screen, press any button.
The screen also goes to sleep (blank) after a period of inactivity. Any movement turns the
screen on again.
3.7. Chest heart rate sensor
Ⓡ
You can use a Bluetooth
Smart compatible heart rate sensor, such as the Suunto Smart
Sensor, with your Suunto Spartan Sport Wrist HR to get accurate information about your
exercise intensity.
If you use the Suunto Smart Sensor, you also have the added advantage of heart rate
memory. The sensor memory function buffers data if the connection to your watch is
interrupted, for example, when swimming (no transmission under water).
It also means you can even leave your watch behind after starting a recording. For more
information, please refer to the Suunto Smart Sensor User Guide.
Ⓡ
Refer to the user guide for Suunto Smart Sensor or other Bluetooth
Smart compatible heart
rate sensor for additional information.
See 3.23. Pairing PODs and sensors for instructions on how to pair an HR sensor with your
watch.
