Annex: 2.4GHz Transmitter Manual
1. The 2.4GHz transmitter and receiver are pre-bound at the factory.
2. Please always use the same receiver model from the factory to match your 2.4GHz
transmitter when you need to replace it. Receivers from other suppliers don't work on DHK
HOBBY 2.4GHz transmitter.
3. When you need to replace a receiver, please make sure that it is bound with the transmitter
before use.
4. Please operate the transmitter in vast areas where no radio interference exists. It's strongly
recommended that no humans, animals or high voltage grid should be nearby.
5. Please do not operate this transmitter during fatigue, sickness, intoxication or in bad mood.
6. Do not operate the transmitter at night time, in the rain and thunderstorm or at low visibility.
7. Always use the same types of batteries in the transmitter. Do not mix old and new batteries
in the transmitter. Please check the battery power before use. Replace batteries whenever the
power is low to avoid out of control. Ni-Mh or Ni-Cd rechargeable batteries can be used on this
transmitter. Please charge the batteries to full before use.
8. Before you operate the transmitter, please check the switch, batteries, servo and ESC for
proper connection. 9. ALWAYS switch on the transmitter first, and off last so as to avoid
possible radio interference from other sources. Failure to do so may cause out of control of
your vehicle.
10. Before operation, check the servo forward and reverse functions, motor range, and neutral
position. Modify it when necessary.
11. Please handle the transmitter with care. Store the transmitter in a dry and clean place
when it's not in use for some time.
