Safety Instructions | 11
12.2 Before commissioning
■
Before every flight, check the functional reliability of your model and the transmitter.
Watch out for any visible damage such as defective plug connections or damaged
cables and wires.
■
All moving parts of the model must run smoothly but should not have any play in their
bearings.
■
Before each operation check the correct and secure position of the propellers.
■
Charge the flight battery.
■
Ensure sufficient residual capacity [ battery tester (not included) ] of the batteries
inserted in the transmitter. If the batteries are empty, always replace the complete set,
never individual cells only.
■
Always switch on the transmitter first before connecting the battery to the Navigator 250.
■
Set the throttle to zero before connecting the battery to the Navigator 250. The motors
might run unintentionally!
12.3 During operation
■
When the motors are running, make sure that neither objects nor body parts are in the
rotating and suction area of the propellers.
■
Do not take any risks when operating the model! Your own safety and that of your
environment is solely down to you being responsible when dealing with the model.
■
Improper operation may cause serious injury and property damage! Therefore make
sure to keep a sufficiently safe distance to persons, animals or objects during operation.
■
Select an appropriate location for the operation of the Navigator 250.
■
Fly the Navigator 250 only if your ability to respond is unrestricted. The influence of
tiredness, alcohol or medication can cause incorrect responses.
■
Do not direct your model towards spectators or yourself.
■
Motor, electronics and flight battery may heat up during operation. Wait 5 to 10 minutes
before recharging or replacing the flight battery.
■
Never switch off the transmitter while the Navigator 250 is in use. After landing, always
disconnect the flight battery first. Only then may the transmitter be switched off.
■
In case of a defect or a malfunction, remove the problem before using the Navigator 250
again.
■
Never expose the Navigator 250 or the transmitter to direct sunlight or excessive heat
for an extended period of time.
■
In the case of a severe crash (e.g. from a high altitude) the electric gyro sensors can be
damaged and/or misadjusted. Therefore, full functionality must be tested before flying
again without fail!
■
In the event of a crash, the throttle should be immediately set to zero. Rotating
propellers may be damaged if they come into contact with obstacles. Before flying
again, these should be checked for possible tears or breakages!
■
Observe the warn/safety signals emitted by the Navigator 250 at all times to avoid
damage (e.g. discharged battery).
12.4 Outdoor flying locations
■
Always and only operate the Navigator 250 in a designated RC flying area.
■
Stay away from power lines, cellphone towers and other sources of potential
interference, and restricted areas.
■
Never fly the Navigator 250 above people.
■
Contact a local RC club nearby to find out more about designated and approved flying
areas.
12.5 Batteries
12.5.1 General information
■
Correct polarity must be observed while inserting batteries.
■
Remove the flight battery from the Navigator 250 after every flight.
■
Remove the batteries from the transmitter if you do not use it for a longer period of time.
Discharged batteries may leak.
