2 - Parts of the tape deck14 TASCAM DA-40NOTEIf the DATA dial is turned by mistake, eitherleave the tape deck alone for five seconds tocancel the operation, or press the STOP key.2.4 Command keysThese command keys have two modes: the primarymode, labeled in white above the key, is the mostcommon use for the key. The secondary, or shifted,mode is labeled in blue above the key, and is onlyoperative when the SHIFT indicator [31] is lit (see 4,"SHIFT functions" for details of these secondarymodes).[20] COUNTER MODEUse this key to cycle through the different tapecounter modes available:• ABS time— the absolute time as recorded on thesubcode of the tape. This is expressed in hours,minutes and seconds. If the tape is at an unrecordedlocation, the tape counter will show all dashes.• PGM time— the elapsed time since the lastSTART ID which has been read from tape (thebeginning of the program). If, when the display isin this mode, the tape is located to a point outside aSTART ID and playback restarts, the tape deck willbe unable to determine the time since the start ofthe program and the display will show all dashesinstead of a time value.• REMAIN time— the time remaining on the cur-rently-loaded cassette; to minute accuracy. Cas-settes from different manufacturers may varyslightly in length, resulting in different valuesbeing shown for tapes which are nominally thesame length.NOTEIn LP mode, the counter shows one second oftape time for every second of real time in theABS, PGM and REMAIN counter modes. Forexample, after one hour’s playback or record-ing in LP mode, the counter will only show 30minutes. Bear this in mind when you are usingthe LP mode.• Tape Counter mode— no indication is given on thedisplay of the mode, and a 4-digit number is usedto show the tape position. This value is relative to auser-definable reference “zero” point (seeMARGIN RESET [22]).[21] CHARIf characters have been recorded on the tape as a tapeor program title, pressing this key will allow the tapedeck to display these characters, scrolling across thedisplay, as the START ID containing the title isplayed back. They will be replaced by successive titlecontents as they are read from tape. If characters areread from a START ID, the CHAR indicator willlight in the display to indicate this. If no charactershave been recorded on the tape, pressing this key willhave no effect.[22] MARGIN RESETPressing this key resets the margin (available head-room) to its lowest level of 40dB. Note that in somedisplay modes, there is no visible effect when thiskey is pressed.The margin is measured in 1 dB increments between40 dB and 20 dB and in 0.1 dB increments between19.9 dB and 0 dB.If the time display is in the 4-digit tape countermode, pressing this key will reset the tape counter.[23] DISPLAYRegardless of the current counter mode set by [20],this key is used to display other information. Theoptions available, which are accessed by repeatedpresses of this key, are:• Program number and Margin mode— where thecurrent program number and margin in decibels aredisplayed:• Frames mode— where frames are displayed aswell as hours, minutes, and seconds. The framesused are “digital audio” frames, i.e. there are 100frames in every three seconds; 33 in the first sec-ond, 33 in the next, and 34 in the third. The patternthen repeats itself.PNO MARGABS0 0H 2 6M 3 5S 0 9 6. 3 dBPNO MARGPGM 0 3M 1 7S 0 9 6. 3 dBPNO MARGREMAIN0 0 0 3M 0 9 6. 3 dBPNO MARG0 1 2 6 0 8 6 . 3 dBPNO MARGABS0 0H 2 3M 0 8S 0 7 6 . 3 dBABS0 0H 2 3M 0 8S _ 3 2F P 0 9
