6.2.2 Group Channel Settings:
1) Set by the Alpha 600 programmer.
2) Set by the encoder board 2

& 3
rd
pin of JP1 and dip-switch.
Auto-cycled group channel: JP1 2, 3 short + dip-switch set as 00000000
Assigned group channel: JP1 2, 3 short + dip-switch set by following below table.
6.2.3 Fixed Channel Mode:
It is for sending signals with fixed frequency. (Whenever there is any area covered by some interference
within frequency 902~928MHz and the remote control operation is not smooth under group channel mode,
fixed channel mode can be used instead. The fixed channel mode is good for some area tested without
frequency interference and the non-interfered fixed channel may be used.)
* For Alpha 604, 607, 608 or 612XJ transmitter, please avoid using the same channel for interference
concern.
* To change from group channel mode to fixed channel mode, only transmitter needs to be converted and
the receiver settings remain unchanged. When the transmitter mode is converted from group channel to
fixed channel, it takes 1~40 seconds for the receiver to search for the transmitter with identical setting
after it is first power on. After the receiver catches the transmitter, the transmitter may operate the
receiver whenever it is power on.
* To avoid the receiver in use from being interfered by the transmitter with adjacent channel, please keep
