Type 99 Operation; Enable/Disable Type 99 - L3Harris XL Extreme Series Operator's Manual

Table of Contents

If the talkaround Indication feature is enabled using RPM2, the radio will play a unique grant tone

when a call is placed on a simplex channel or when talkaround 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

talkaround. If configured, the radio plays the tone at the selected volume level.

NOTE

Talkaround 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 talkaround 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 "talkaround" grant tone

when a call is placed. The radio does not play a tone when a call is received.

•

Transmit and Receive: When this option is selected, the radio plays a different "talkaround"

grant tone when a call is placed, and at the beginning of a received call.

NOTE

5.24 TYPE 99 OPERATION

Type 99 is L3Harris' 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 radio detects the second tone, it sounds the appropriate Type 99 alert

tone. After the second tone stops, the receiver audio path is opened for the user to receive

messages.

To enable Type 99:

1. Press Menu/Select button to access the main menu.

2. Press the left or right navigation buttons to display the CALL menu.

3. Press the up or down navigation buttons to highlight T99 TOGGLE.

The tone will not play on systems configured with MDC.

In the radio personality, the "Alert Tone" parameter must be enabled for each

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.
