7.3 Preventive maintenance 
 
A few simple checks can bring to light certain defects which can later be the cause of 
subsequent break-downs and which can be readily rectified. We recommend the following 
checks to be made from time to time: 
 
Transmitter: 
 
 Check the transmitter’s closing screws to make sure they are securely tightened. 
 Check the rubber protection seals on the transmitter’s command buttons from time to 
time. Replace them if they are found to have deteriorated. This will protect the unit’s 
watertightness. 
 Keep the battery contacts clean. 
 
 
Receiver: 
 
 Check to make sure the cable fixture screws are tight. 
 Check the contacts on the fuses and the fuse-holders. 
 
 
Battery charger and batteries: 
 
 Keep all contacts clean. 
 
7.4 Locating Break-downs 
 
The transmitter and receiver both have status monitoring LEDs which help to identify 
irregularities. The most common signals are contained in the tables below:
