2-TONE DECODE OPERATION

To use 2-Tone Decode the "Display Series" base station
must be PC programmed for this option, the radio does not
operate with 2-Tone decoding as it is received from the factory.
See your Ritron dealer or contact Ritron directly for PC
programming of this option. This feature allows the base station
to act as a monitor receiver.
To activate 2-Tone Decode you must first select a radio channel
that has been PC programmed for 2-Tone Decode. The factory
default setting will automatically activate 2-Tone Decode any
time the 2-Tone Decode channel is selected. If not,
simultaneously press both of the volume buttons and hold briefly
before releasing. The radio sounds three beeps when 2-Tone
Decode is turned on.
If you are unable to set the base station, you have selected a
channel that is not programmed for 2-Tone Decode.

OPERATION
When the base station decodes an incoming 2-Tone signal it will
emit a "ring' tone similar to a telephone and the display will show
a "C" to indicate that a call has been received. You can now
proceed with normal two-way communication until the 2-Tone
Decode feature has been reset. The "ring" tone will sound every
time a 2-Tone signal is decoded.
The display will show a "C" to indicate that a 2-Tone call
has been received.
To reset 2-Tone Decode after receiving a call: Simultaneously
press both of the volume buttons and hold briefly before
releasing. The base station sounds three beeps when 2-Tone
Decode is reset and the display will show the channel number.
The base station can be optionally programmed to automatically
reset if a call is not answered within 15 seconds.
2-Tone Decode channels can be programmed to:
• Automatically set the base station for 2-Tone Decode mode
whenever the channel is selected.
• Automatically reset if a 2-Tone Decode is not answered
within 15 seconds.
• Automatically place the receiver into carrier squelch "monitor"
mode whenever a 2-Tone Decode has been decoded.
• Send a transpond tone back to the transmitting station to
confirm that the 2-Tone signal has been received.

• Decode a Group Call if the first tone is sent for an extended
period of time.
