IFHHFMS-CAR-75REMOTE CONTROL - TRANSMITTER

PROFI CAR 403 and 707 Operating instructions Before operating the transmitter, please select the language (see 9.4, page 42)! 2 Dear customer, dear fellow modeller, we are delighted that you have decided to purchase a MULTIPLEX radio control system. The „PROFI CAR“ is the first „pistol-grip“ transmitter designed and developed by MULTIPLEX. Ergonomic efficiency and user-friendliness were our top priority during the development process. That’s not to say that we have neglected performance: the new system includes many innovative and practical features, offering you facilities which until now have not been available in systems of this class. They include: v Interchangeable RF module, switchable to suit AM and FM receivers v Up to 7 channels (steering, throttle/brake + 5 auxiliary channels) v 2 steering servos and 2 brake servos (PROFI CAR 707 only) v Separate throttle servo (PROFI CAR 707 only) Of course, you don’t need to use these features; you can still operate the PROFI CAR as a „completely normal“ set, i.e. with one steering servo and a second servo for throttle/brake. We are confident that you will have many hours of pleasure with your PROFI CAR.

You can make a major contribution to safety when operating your models by acting responsibly and handling your radio control system and model with due care. v Check the electrical and mechanical connections in the model at regular intervals. v Check all moving parts regularly: they must be free to move, and must not exhibit undue lost motion. v Carry out regular range checks (see „Range testing“). v When other drivers are present at the track, find out which channels are already in use before you switch on. v Before every run: extend the transmitter aerial to full length, and check that it is in good condition and firmly seated. v Check that you have selected the model memory corresponding to the model you are running. v Check all the working systems in your model before you start: Do the servos rotate in the correct direction? Are the travels correct? v Are the transmitter and receiver battery adequately charged, and in well maintained and roadworthy condition? v Use only genuine MULTIPLEX crystals, batteries and accessories. v If your receiving system includes components which are not covered by these operating instructions, be sure to read the instructions supplied with those items. If you are in doubt on any point - don’t operate your model! Take your time, carefully check the system again, and eliminate the fault. If you cannot solve the problem, your local model shop or the MULTIPLEX customer service department will be pleased t…
