NOISE BLANKER OPERATION
A noise blanker feature is available in the low band (29-50 MHz) version of
the Orion radio which provides ignition noise filtering. The feature can be
enabled through either the pre-programmed menu selection or a pre-pro-
grammed key on the control unit. The noise blanker state is remembered
through a power cycle and its state will be displayed at power-up (i.e.,
NB
ON
or
NB OFF
). The menu selection or the pre-programmed key will tog-
gle the state of the noise blanker and display the new state.
Menu Selection

TYPE 99 DECODE (Conventional Only)
If the Type 99 Decode Option has been pre-programmed, individual selective
calling is possible. The radio can now decode individual, group or super-
group paging calls. Two sets of Type 99 paging codes must be pre-pro-
grammed 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 ap-
propriate Type 99 alert tone will sound again if it detects a valid two-tone se-
quence.
