The CTCSS encoding and decoding frequencies may be set differently.
The encode setting frequency automatically relates to the decode
setting, but decode setting does not affect encode. The standard set of
50 different CTCSS tones are available. DCS encode/decode cannot be
separated. The list of selectable tones and codes is shown on Appendix
at the end of this booklet.

positive offset, which means transmitting
frequency higher than receiving frequency.
Repeater receives a signal(UP-LINK) on one frequency and re-transmits
on another frequency(DOWN-LINK). The difference between these two
frequencies is called the offset frequency. If the UP-LINK frequency
higher than DOWN-LINK frequency, the direction is positive, If it is lower,
the shift direction is negative.
