2-tone Decode Frequency Tolerance
2-tone Decode Frequency Tolerance can be used to change the 2-tone decode response bandwidth depending on the
status of the system.
If the transceiver cannot decode a frequency, a larger value must be configured. If the transceiver decodes a different
frequency erroneously, a smaller value must be configured.
The transceiver can decode the frequency if the received 2-tone frequency is within the range configured for 2-tone
Decode Frequency Tolerance while the transceiver is waiting to receive A Tone, B Tone, C Tone, and D Tone frequency.
For instance, the transceiver determines that A Tone has matched if the received tone frequency does not exceed the
range between 315.9094 Hz (321.7 Hz x 0.982) and 327.4906 Hz (321.7 Hz x 1.018) when 321.7 Hz is configured for the
A Tone frequency and ±1.8% is configured for 2-tone Decode Frequency Tolerance. However, this configuration can be
used only as a guide, hence the Decode Response Bandwidth has a slight margin.

10.5 Using FleetSync to Initiate a Selective Call
Using FleetSync, the transceiver can initiate an Individual Call, a Group Call, or various message communications in an
Analog Conventional system.

10.6 Using DTMF to Initiate a Selective Call
DTMF Encode and the related functions can be used in an Analog Conventional system.
To decode a DTMF code in an Analog Conventional system, "DTMF" needs to be configured as the Optional Signaling to
be used on the channel. (Refer to
