Power cycling the radio does not disable talkaround.

If programmed for Talkaround enable/disable, use :
See Table 3-1 for the various options that can be programmed to the switch.
If the Talk-Around Indication feature is enabled in RPM, the radio will play a unique grant tone when a
call is placed on a simplex channel or when Talk-Around has been enabled on a duplex channel. This
feature applies to both Analog and P25 Conventional systems. It optionally allows the radio to also play
the same tone when it receives a call while operating in simplex or Talk-Around. If configured, the radio
plays the tone at the selected volume level.
The tone will not play on systems configured with MDC.
Talk-Around Indication can be specified for each individual Analog and P25 Conventional system
configured in personality. The following options can be selected, and apply only when the radio is on a
simplex channel or when Talk-Around has been enabled by the user:
• Disabled: (This is the default option.) When this option is selected, the radio plays the standard grant
tone when a call is placed. The radio does not play a tone when a call is received.
• Transmit Only: When this option is selected, the radio plays a different “Talk-Around” grant tone
when a call is placed. The radio does not play a tone when a call is received.
• Transmit & Receive: When this option is selected, the radio plays a different “Talk-Around” grant
tone when a call is placed, and at the beginning of a received call.
In the radio personality, the “Alert Tone” parameter needs to be enabled
channel on the Conventional Frequency Set. The “Ready To Talk Tone” parameter
must also be enabled for the Talk Around Indication tone to be played when the radio
is keyed.
3.19 TYPE 99 OPERATION
Type 99 is Harris' name for in-band, two-tone sequential signaling. It is a conventional signaling protocol
used to control the muting and unmuting of a radio. This signaling is commonly used for selective calling
of individual units or groups of units in a conventional system.
In Type 99 tone systems, calls are not heard until the radio detects the proper two-tone sequence. This, in
conjunction with squelch, prevents the user from hearing noise or undesired conversations. When the
