16. Battery change
a) Pulse watch
• If the display no longer shows anything, the battery must be replaced.
☞
If you do not have the required specialist knowledge for battery change, contact a
specialist.
• First remove the 4 screws on the back of the watch.
• Carefully remove the rear housing lid. Ensure that the
seal is not damaged.
• Now you need to loosen the clamp that
holds the battery. Best use a pointy ob-
ject for this, e.g. a thin paper clip or a
needle.
Move it into the small slot and lever out
the clamp.
• Now lever out the battery with a pointy
object as well and take it out.
