Type 99 operation may be reset manually or automatically (pre-pro-
grammed). Manual reset is achieved by briefly pressing
c
, if pro-
grammed. 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-pro-
grammed 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 de-
pending upon its present state.
To check the Type 99 enable status, press the Scan Add/Delete

is displayed in the third segment from

If a Horn Alert Option is installed and enabled with the Type 99 Decode Op-
tion, 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 re-
ceived.
