Replacing the battery
Pull the groove on the left side of the battery case at the bottom of the reverse side of the remote control unit to the right.
In this state, pull the battery case downwards.
Insert the lithium battery (CR2025) correctly into the battery compartment as indicated.
Replace the battery case in the original position.
NOTE
When inserting the lithium battery, be sure to do so in the proper direction, following the 
and 
marks in the battery compartment.
If the battery should have a leakage, immediately replace and dispose of the battery. In this case, there is a risk of burn when the liquid comes in contact with skins or clothes, so a great care should be taken. If the liquid accidentally comes in contact, wash with tap water and consult a doctor.
Remove the battery from the remote control unit if it will not be in use for long periods.
