always starting in preset channel 0 at power up. (Reference: Paragraph 2-3.2.1 and Table 3-3,
"P" code.
2-6.1.4 Storing Presets
This command allows the user to change the stored information for the current preset
channel. (Receive/transmit frequency, and selection of AM or FM. Excessive use of the Q
command may result in defective channel data and/or the transceiver may always start in preset
channel 0 at power up. (Reference: Paragraph 2-3.2.6 and Table 3-3, "Q" code.
2-6.2. ALIGNMENT COMMAND LIMITATIONS
The following alignment commands should be used only as needed.
2-6.2.1
Warp Alignment Command
This
is a factory setting used to set the crystal warp. This value should rarely require
adjustment (typically once
a year or less often). Excessive use of the warp command may result
in defective crystal operation and/or loss of lock at some or all frequencies and/or the transceiver
will behave as if factory initialization has not been completed. (Reference: Table 3-3, "W" code.
2-7. ERROR MESSAGES
The following eight error
messages are produced by the URC-200 (V2) Transceiver and are
displayed
on the front panel screen. The displayed error, the error title, and a description of the
error are indicated below in Table 2-2.
Table 2-2. Error Messages
Display Error Title Description
Err – bEAC Beacon Lock Failure This message indicates that there is no
synthesizer lock on beacon.
Err – EEPr EEprom Failure This message indicates that data could not be
written into the EEPROM and that the processor
should be replaced.
Err – FACt Factory Init Incomplete This message is produced after the installation
of a newly programmed microprocessor. It
indicates that the initialization has not been
completed for this transceiver.
Err – noSC Scan Error This message indicates that an attempt to begin
scanning failed because less than two channels
are selected for Scan mode.
Err – trPr PA Path Over This message indicates that the VFWD is below
the calculated threshold value.
Err – UOLt Voltage Out of Range This message indicates that the 70 volt supply is
out of its normal range either high (>80 V) or low
(<60 V).
tOO – HOt Over Temp Error This message indicates that the transmitter’s
power amplifier temperature is above normal
range. When this alarm condition exists, the
transceiver will automatically reduce the
transmitter power by half until the temperature
returns to normal range.
