GENERAL DESCRIPTION

RF Frequency
For units equipped with the optional integral radio receiver, the RF Frequency
configuration parameter sets the frequency of the radio channel. Changing this
parameter from its factory setting may require re-alignment of the radio for maximum
performance. The value entered must fall within the range specified for the receiver
band equipped.
Single-Tone, Two-Tone Timing
For Two-Tone activated units, the Two-Tone Timing parameters set up the time
duration of the activation tone codes. The three parameters, A-Time, B-Time, and S-
Time; sets the time duration for the A-tone, B-tone, and Single-Tone respectively. Note:
The Two-Tone timing parameters are minimum values only. The actual tone times may
be longer than the specified times.
EAS Location Codes
Up to three location codes may be assigned for EAS activation. For activation to occur,
the location code of the received EAS message must match one of the three assigned
codes.
Units cannot be programmed for both Tone and EAS activation at the same time.
Therefore, when using EAS decoding, the A-Time, B-Time, and S-Time parameters
above must be set to zero. The UVIC is capable of being programmed for EAS, DTMF
and Federal Digital decoding at the same time. Refer to www.fcc.gov for further
information about EAS messages.
128-bit Encryption Key
For MSK activated units, 128-bit data encryption provides security against malicious
operation or monitoring. The 128-bit key is programmed during the flashing of the
microprocessor and must match the encoder (SS2000D or SFCDWARE) being used to
activate the unit. A key value of zero disables 128-bit encryption and must be used if the
encoder does not support 128-bit encryption. All sites in the system must use the same
encryption key.
