BASIC OPERATION
■
Repeater operation
A repeater amplifies received signals and retransmits them
on a different channel, allowing you to communicate over
greater distances with improved reliability. When using a re-
peater, the transmit channel is shifted from the receive chan-
nel by 30 channels.
q
Select the receive channel from 1 to 8 (repeater output
channel).
w
Push [DUP] to set duplex.
• “DUP” appears.
• The duplex setting affects the selected channel only and is auto-
matically programmed into the selected channel.
e
Push and hold [PTT] to transmit.
• The displayed channel automatically changes to the transmit
channel (repeater input channel).
• If “T SQL” appears on the display, push [–] for 2 sec. twice to can-
cel the tone squelch function.
r
Release [PTT] to receive.
t
To cancel the duplex setting, push [DUP] on the desired
channel.
D
Setting CTCSS tones for
repeater and tone squelch
operation
Repeaters may require CTCSS (subaudible) tones to be ac-
cessed. CTCSS tones are superimposed over your normal
signal and must be set in advance.
This setting is commonly used for the tone squelch operation.
q
Select the desired memory channel to be programmed.
w
Push [LOW] for 2 sec. to enter set mode.
e
Push [LOW] several times until “Ct” appears.
r
Push [
Y
] or [
Z
] to select the CTCSS tone frequency.
t
Push [LOW] for 2 sec. to exit set mode.
