Type 99 operation can be reset manually or automatically (pre-programmed). Manual reset is achieved by
briefly pressing
CLR, if programmed. Automatic reset, if enabled, occurs after a 30 second interval
following the most recent decode of a Type 99 tone sequence. Hookswitch (pre-programmed) can also
enable or disable Type 99 decode. The pre-programmed key light will blink when Type 99 is disabled by
the hookswitch.
Type 99 decode will continue to be active while the radio's CLR button is pressed. This allows the user to
monitor calls and still be alerted when a call is directed to the user. While the user continues to press
CLR, the user will hear both calls and all Type 99 tone signals. If CLR is pressed for longer than two (2)
seconds, Type 99 decode will either be disabled or re-enabled depending upon its present state.
To check the Type 99 enable status, press the Scan Add/Delete
ramp control. The current status
of Type 99 decode will be displayed for a time-out period.
If a Horn Alert Option is installed and enabled with the Type 99 Decode Option, the radio can beep the
vehicle horn when a Type 99 call is received. This option permits alerting persons out of the vehicle when
a call is received.
Type 99 is automatically disabled when Scan is enabled.

message is displayed for two seconds to show the new state.

10.13 DIRECT MODE OPERATION
The direct mode (or talk-around) provides short range, line of sight communications. One of the buttons
on the control unit must be pre-programmed for this feature to function.
1. Make sure the radio is ON and then select the desired conventional system and channel.
2. Press the pre-programmed button to toggle the talk-around function ON.
3. Ensure that the channel is not busy by pressing the CLR (System version) or CLEAR (Scan version)
to briefly disable any channel decoding and unmute the receiver or observe the unlit BSY indicator. If
the Channel Busy Lockout feature is programmed for the selected channel, the radio will not transmit
when the channel is busy.
4. Press and hold the PTT button. The TX indicator will light and a short beep sounds (if pre-
programmed) indicating that communication can begin.
5. Release the PTT button when the transmission is complete and listen for a reply.
6. When the communication is completed, press the pre-programmed button to toggle the talk-around
function OFF.
