9.12 TYPE 99 DECODE

If the Type 99 Decode Option has been pre-programmed, individual selective calling is

possible. The radio can now decode individual, group or supergroup paging calls. Two sets

of Type 99 paging codes must be pre-programmed into the radio. When the radio decodes an

appropriate Type 99 code sequence, an alert tone and visual indicator is provided to the

user. The receiver then operates as a noise squelched unit until Type 99 is reset. Type 99

decode continues to operate during this noise squelched period. The appropriate Type 99

alert tone will sound again if it detects a valid two-tone sequence.

Type 99 operation can be reset manually or automatically (pre-programmed). Manual reset

is achieved by briefly pressing CLEAR, if programmed. Automatic reset, if enabled, occurs

after a 30 second interval following the most recent decode of a Type 99 tone sequence.

Hook switch (pre-programmed) can also enable or disable Type 99 decode. The pre-

programmed key light will blink when Type 99 is disabled by the hook switch.

Type 99 decode will continue to be active while the radio's CLEAR 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 CLEAR, the user will hear both calls and all Type 99 tone

signals. If CLEAR 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.

NOTE

Type 99 is automatically disabled when Scan is enabled.
