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
 
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) 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 
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. 
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.
