■ Repeater operation
A repeater amplifies received signals and retransmits
them at a different frequency. When using a repeater,
the transmit frequency is shifted from the receive fre-
quency by an offset frequency. A repeater can be ac-
cessed using split frequency operation with the shift
frequency set to the repeater’s offset frequency.
For accessing a repeater which requires a repeater
tone, set the repeater tone frequency in tone fre-
quency set mode as described below.

D Repeater tone frequency setting
Some repeaters require subaudible tones to be ac-
cessed. Subaudible tones are superimposed over your
normal signal and must be set in advance. The trans-
ceiver has 50 tones from 67.0 Hz to 254.1 Hz.
