DYNAMIC VOLUME CONTROL (DVC)
The modulation level of signals heard on the UHF CB band
has always varied considerably resulting in noticeable
differences in received audio volume between stations.
Generally users have compensated for this by adjusting the
volume control for each received signal. With the introduction
of 80 channel narrowband transmissions that use lower levels
of modulation, the diversity in received audio volume is likely
to increase further.
The TX3500S is able to automatically compensate for these
variations in received audio level by utilising a Dynamic
Volume Control. When activated, this feature automatically
compensates for variations in received audio level resulting
in a constant audio output level to the speaker to greatly
enhance the quality of the reception.
To switch the Dynamic Volume Control ON or OFF
1. Press and hold the
Channel
Control to enter the Menu.
‘br’ will be displayed.
2. Press the

SILENT SQUELCH TAIL
The Squelch Tail is the short burst of noise that is heard
in the speaker at the end of a transmission before the
Squelch closes.
To some it is a reassuring confirmation that it is their
turn to transmit but in some applications it may be an
annoyance especially when listening through an earpiece
or headphones.
The Silent Squelch Tail function removes this Squelch Tail,
reducing it to a faint click as the Squelch closes.
To enable or disable the Silent Squelch Tail
1. Press and hold the
Channel

the Silent Squelch Tail. ‘oF’ will be displayed and the
Squelch Tail will be restored.
When finished, press and hold the

REPEATERS AND DUPLEX MODE
Duplex operation allows the radio to transmit on a different
frequency to that which it receives. This allows operation
through repeater stations.
A repeater station consists of a linked transmitter/receiver
combination installed in a prominent location. The repeater
is designed to receive signals on a designated channel and
