Tip Continuous depression of the SET key permits the display to cycle through the channel
numbers.
On the receiver side, when the dot LED by the channel number LED is blinking at
selected channel number, this means that the channel isalready occupied.

number display turns on the light for about 20 seconds, and
then this display turns off the light. When SET key presses in
this condition, this display turns on the light for about 20
