KEN 2 Channel FM RECEIVER (continued)

Frequency Selection

Ken is a crystal-free receiver. You do not need crystals to change frequencies. In a
North American model, as an example, all 30 channels in the 75MHz band are
available at your fingertip. Each available frequency is assigned with a two-digit
channel number which can be referenced in the [Frequency Chart] located in the
Appendix section of this manual. A two-digit LED display on your Ken shows the
channel number of your chosen frequency. To change the channel number, follow
the steps below:
1. First ensure that your model will not run out of control in any event during the
process of selecting or changing frequencies. For engine powered models, make
sure the engine is not running. For electric powered models, make sure the
wheels are not in contact with the ground or any objects.
2. Make sure your transmitter is powered on with your desired frequency already
set.
3. Switch on the power to the Ken receiver. The current set channel is displayed
on the LED for about 3 seconds.
4. FOR KEN RECEIVERS SOLD IN EUROPE, press left button to change the 1st
digit and the right button to change the 2nd digit of a channel number.
FOR KEN RECEIVERS SOLD IN NORTH AMERICA, press the left button to
decrease or the right button to increase the frequency channel number. Press
either button repeatedly until your desired channel number is reached. Once the
LED display goes off in about 3 seconds, your Ken receiver is turned and ready to
receive signal.
At anytime, by pressing either button momentarily will bring your last set channel
number to the LED display. Subsequent press of either button while the LED is lit
will change the channel number.
Your Ken receiver uses non-volatile memory technology to store its settings. This
means your set channel will not be lost even after the power is disconnected.
NOTE Your Ken receiver's frequency should always be set to match your transmitter's
frequency. Otherwise the receiver may receive unwanted signals from other sources, causing
an unexpected accident and damage your model. Make sure to turn the power off when not
in use.
