b) Sensor
• if the pulse watch cannot establish any connection to the sensor anymore, the battery must be
replaced.
• For this, remove the battery lid on the rear of the sensor. This works most easily with a small
coin that fits into the slot.
• To open it, turn the lid slightly to the left until the point of the lid points at the place marked
“OPEN”.
• Remove the lid, take out the old battery and insert the new one (CR2032). Always ensure cor-
rect polarity. If the sensor is placed with the battery compartment up, the plus pole must point
up as well.
• Now apply the lid again (the point on the lid must point to “OPEN” and lock it with the coin. Turn
it to the right until the point on the lid points at “CLOSED”.
• The battery change of the sensor is now completed.
