Resetting Type 99 After A Call
When a Type 99 call is decoded, the radio enters Monitor mode. The
Type 99 decoder will now operate in the background. If the radio is
called again, the Type 99 decoder will decode it and sound the call's alert
tone. But the decoder will no longer mute the audio. All traffic on the
channel will now be heard. (If the channel has Channel Guard, only the
traffic with the radio's Channel Guard tone will be heard.)
In order for the Type 99 decoder to mute the audio, it must be "Reset".
There are several methods of doing this.
1. Press the Monitor/Clear button.
2. Place the microphone on its hookswitch. (If the
hookswitch function is enabled.)
3. Press the Type 99 On/Off button.
4. Allow an optional "Auto-Reset" timer to reset the
Type 99 decoder. This is a programmable option.
The time is also programmable between twelve
seconds and three minutes.
PROGRAMMABLE PTT FUNCTIONS
Channel Busy Lockout
The radio may be programmed to deny the use of the transmitter when
the channel is busy. This keeps another radio from interrupting a
message that is in progress. This is called Channel Busy Lockout.
If the PTT switch is pressed while the Busy/Tx LED is on, the radio will
display "LC" for "Locked Channel" and sound an alert tone until the
PTT is released.
Channel Guard Channel Busy Lockout
The radio may be programmed to deny the use of the transmitter when
the channel is busy with another Channel Guard tone. The radio will
transmit when the channel is busy with the radio's Channel Guard tone.
This is called Channel Guard Channel Busy Lockout.
