REPEATER AND DUPLEX OPERATIONS
■ Repeater operation
For your reference:
• If the Repeater tone frequency or the frequency offset
is changed, the tone or offset for the Auto Repeater
function is also changed.
• If the offset value will cause the transmit frequency to be
out of the band, "OFF" will be displayed when [PTT] is
pushed, and transmit will be inhibited. (p. 51)
D Checking the repeater input signal
You can check whether another station's transmit signal can
be received directly or not, by listening to the repeater input
frequency.
z Push [MONI DUP]C to listen on the repeater input
frequency.
• While monitoring, "BUSY" blinks.
• While monitoring, the displayed frequency automatically
changes to the transceiver transmit frequency (repeater input
frequency).
• When the other station's signal can be directly received, move
to a non-repeater frequency and use simplex. (Duplex OFF)
• While monitoring, the Attenuator function is temporarily
disabled to receive a weak signal.
