Work Procedure:
1. Replacing the remote-control battery.
1.1 Take a new battery out of the package and set it aside.
1.2 Removing the battery.
Caution!
Damage to the processor due to voltage drops or voltage peaks!
> Do not press any button of the remote control directly before replacing the battery and during the replacement.
1.2.1 Carefully lift off the cover of the key head with a finger nail or a small screwdriver.
1.2.2 Unclip battery on the recess of the top of the battery (Figure 1, arrow 1) with a finger nail upwards out of the holder.
1.2.3 Pull out battery from the tab (Figure 1, arrow 2).
1.3 Installing a new battery.
Caution!
Damage to the processor due to voltage drops or voltage peaks!
> When installing the battery, do not press any button on the remote control and avoid repeated contact between battery and contact
pins.
1.3.1 Slide new battery with the positive terminal upwards under the tab (Figure 1, arrow 2).
1.3.2 Clip new battery downward into the holder.
1.3.3 Put the cover on the key head.
1.3.4 Press together the key head and cover tightly until the cover engages audibly.
1.4 Check the function of the remote control.
Note:
If the remote control does not function after replacing the battery, the processor could have stopped. If this is the case, the LED of the
remote control either does not light when the button is pressed or it lights continuously, i.e., longer than length of time the button is
pressed. The processor must be restarted. In this case, proceed as is described under Step 2.
2. Restarting the processor.
2.1 Remove battery as described under Step 1.2.
2.2 Inserting battery briefly with polarity reversed.
2.2.1 After a waiting time of at least 10 seconds, slide battery with the polarity of the battery reversed (positive terminal downwards) under
the tab (Figure 1, arrow 2).
