A.2 SELECTING THE RF CHANNEL
Pressing the first level of the UP and DOWN buttons selects the next higher or next lower RF
channel respectively.
Alternatively, holding down the second level initiates a fast run (approx. 0.3 seconds per
channel) in order to set the system to the desired RF channel (see example Table A-1, above).
When the desired RF channel has been selected, pressing the ON button stores the selected
RF channel in the OCU, exits the programming mode and switches off the OCU.
When the OCU is switched on again it then transmits on the selected channel.
NOTE: After the first activation of the OCU following an RF channel change, it
can take up to 1-minute before the MCU is ready for operation.
