Type 99 operation may be reset manually or automatically (pre-
programmed). Manual reset is achieved by briefly pressing c, 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) may 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 c 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 c, the user will
hear both calls and all Type 99 tone signals. If c 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 < or >.
The current status of Type 99 decode will be displayed for a time-out
period. Type 99 is enabled when the letter T is displayed in the third
segment from right on the first line of the LCD display.
If a Horn Alert Option is installed and enabled with the Type 99 Decode
Option, the radio can beep the vehicle horn whan 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.
