D MONITOR AUDIBLE FUNCTION
The monitor function allows you to open the transceiver's squelch
manually to check whether a channel is busy or not. The trans-
ceiver has 2 conditions for receive standby:
All signals are received.
Only signals containing the
proper tone are received.
D TALK AROUND
The talk around function changes duplex channels to simplex chan-
nels.
• Duplex allows you to contact your base station, repeaters, etc.
• Simplex allows you to contact other portable transceivers directly
(portable-to-portable contact).
Push the [Talk Around] switch to toggle the function ON and OFF.
