The Spectra radios report most problems detected during the self-check on power up. These will be shown on the control head's Vacuum Fluorescent Display (VFD). They will be in one of three formats:

ER xx/yy or ERROR xx/yy
FL xx/yy or FAIL xx/yy
FAIL nnn

Where 'xx' and 'yy' will be hexadecimal characters (0-9, A-F), and 'nnn' will be a decimal value (000-999).

Problems displayed with the 'xx/yy' format consist of a two-digit prefix ('xx')that identifies the source of the problem followed by a two-digit code ('yy') that specifies the particular problem. For example, a radio FAIL code may look like this: 'FAIL 01/90', where the first two digits ('xx' in the format above, '01' in this example) identifies the source of the error and the second two digits ('yy' in the format above, '90' in this example) is a unique error code that identifies the particular problem or trouble.

Problems displayed with the 'nnn' format are usually associated with temporary conditions that may go away if a different mode is chosen.

A FAIL message is fatal and the radio will usually not work at all. Many ERROR messages will still allow the radio to work at reduced capacity, depending on the identified problem. For example, a disconnected external device or accessory will cause an ERROR message but the radio may still operate just fine without it.

NOTE: If you get the dreaded 'FAIL 01/82' message after writing a code plug to the radio, read the code plug from the radio (F2) then immediately write it back to the radio (F8, F8). This usually fixes the checksum problems.

The A9 control heads can display 11 characters. Problems will be shown with the full word 'ERROR' or 'FAIL', followed by the error code prefix and error code. All other control heads with eight-character displays show the message beginning with 'ER' or 'FL'. Hand-Held Control Heads (HHC) display errors with their two seven-segment LED characters by first flashing 'Er' or 'FL', then the error code prefix, then the specific error code. For the three-digit fail codes such as FAIL 001 or FAIL 999, the HHCH displays 'FL 00 01' or 'FL 01 99'.

These lists contain all the FAIL and ERROR prefixes and codes I could find in the manuals I have, but there are probably more. Use this list as a quick reference for locating problems. For example, if a radio is programmed to use the Siren/PA and you see an 'ERROR 08/10' for a moment when you power up the radio, it means the Siren/PA Option is either not connected or is not working.

In general, device codes 00-1F are for a single radio system. These will have 20 (hex) added to them for the primary radio in a dual radio system (20-3F) or 40 added to them for the secondary radio in a dual radio system (40-5F).

It is common to find used radios displaying error messages when a new owner powers up the radio for the first time. This often happens if previously installed options have been removed or are not included with the radio. These errors should disappear when the radio and control head are correctly reprogrammed with the missing options disabled in the code plugs (sometimes a Personality Board also has to have its internal jumper settings changed).

Even though the manuals do not say so, a '2F/yy' error code would probably be the DTMF board in a primary radio. Likewise, a '4F/yy' error would probably be the DTMF board in a secondary radio. If you take a close look at the codes in the list, you can see the repeated pattern in the primary and secondary radio error codes. The same would apply to the MDC options, however, the VRS is not available on dual radio systems. Of course the 'yy' in these e
