6. Inserting the battery, replacing the battery
•
Open the battery compartment on the rear by turning the battery
compartment cover clockwise slightly using a coin (the arrows are in
the 'open' position).
•
Insert a 'CR2016' lithium button battery, observing the correct polarity.
The plus ('+') pole has to point outwards towards you.
•
Replace the battery compartment cover and close it by turning it
anticlockwise (position 'closed').
•
If the LED on the front side of the hand-held transmitter does not light
up when you press the buttons or you find that the range of the hand-
held transmitter decreases, then you need to replace the old battery
with a new one.
