Changing the remote control battery
Models S4 C1 Red and S4 C221 Green
Each remote control contains a single long-life lithium battery (CR1616). This battery will normally last at least 12 months.
Normal range for the remote control is around 10 metres. As the battery within the remote comes to the end of its life you
will notice a reduction in its range and the battery should be replaced.
To replace the battery remove the small screw from the ‘key end’
of the remote and split the two halves of the case.
CARE: The screw is threaded into a sleeve nut on the other half of the remote
take care not to loose this piece.
NOTE: Take care not to lose the screw and ignition key
blade/transponder if the key conversion has been carried out.
Lift the printed circuit board from the remote and slide out the circular battery
from its holder noting the polarity.
Maintaining the polarity of the battery, slide the new battery into the battery
holder.
Fit the PCB into the rubberised holder.
After checking any OE transponder chip is still located within the top half of the
casing fit the assembly into the top casing so the Grey and Black buttons drop
into their respective holes.
At this stage it is a good idea to press the remote control buttons to check they
are operating correctly, this will be shown by the LED of the remote control
illuminating and the alarm disarming/arming if in range.
Refit the ignition key blade into its holder, if required. Clip the bottom casing to the top half and replace and tighten the
screw, so holding the two halves securely.
