ANALOG CONVENTIONAL SYSTEM
In an Analog Conventional system, communications are realized by sending and receiving analog signals on an analog
channel. The transceiver can make an Individual Call or a Group Call using Optional Signaling such as DTMF, 2-tone, and
FleetSync.

Note
This chapter describes the relevant transceiver behavior in an NXDN Conventional system too in case the transceiver is operated in
Mixed Mode.
10.1 Initiating Voice Communications
(Basic Transmission and Reception)
This section describes the basic methods for transmission and reception in an Analog Conventional system and the
relevant functions.
Receiving
Received audio sounds from the speaker if the transceiver receives digital signals, and the frequency matches the
frequency of the channel on which the transceiver has waited for or the Optional Signaling matches the Optional Signaling
preconfigured for the transceiver. When the signaling (QT/DQT) is used, communications are possible if the received QT
tone or DQT code matches the QT tone or DQT code for which the transceiver waits.
Temporarily Disabling the Squelch (Squelch Off)
Squelch Off is the function to allow the transceiver to open the squelch and unmute the speaker.
With this function, the transceiver can unmute the speaker without receiving a carrier. A user can use this function to
monitor the availability of channels prior to transmitting in order to prevent from interfering with other parties.
To use this function, the Squelch Off or Squelch Off Momentary key must be assigned.
Or, pressing the Menu key causes the transceiver to enter Menu Mode, and then "Squelch Off" can be toggled between
enabled and disabled by selecting Squelch Off. (Refer to
