TIME COUNTER & ABS/REL BUTTON

The TIME Counter (found at the top left section of the display) is used to indicate the

current tape position.

ABS 0H 15M 48S 21

The [ABS/REL] button toggles the TIME counter between Absolute Time mode and

Relative Time mode. The XT will indicate which Time mode is selected by either

displaying ABS (for Absolute Time) or REL (for Relative Time) just to the left of the

TIME counter.

REL 0H 01M 29S 03

ABS Absolute Time: This is the XT’s time reference, which is created when a

tape is formatted.

REL Relative Time: This is based on the XT’s time reference of a formatted tape,

but is relative to where the tape was positioned when LOCATE 0 was stored.

J

The Locate Points ‘ addresses are displayed in the format of the display mode you’ve

selected.

See the

Autolocation

section later in this chapter for more information about the

difference between ABS Time and Relative Time.

• When no tape is present the counter will display “-- -- -- --”.

• When an unformatted tape is played, the display will read “noFo” and the

FORMAT icon will flash.

The TIME counter (in either Absolute Time or Relative Time modes) indicates time

code in hours:minutes:seconds.100ths-of-seconds.

0 : 03 : 28 : 15hours

minutes seconds

100ths-of-seconds

LOCATE 0

Pressing the [LOCATE 0] button will take you either to the absolute 0:00:00.00

position (if ABS Time mode is selected) or to the relative 0:00:00.00 position (if

Relative Time mode is selected). The Absolute 0:00:00.00 position never changes,

since it is derived from the timecode that was written onto tape during the formatting

process. The Relative 0:00:00.00 position is user-definable.

You can set the Relative 0:00:00.00 position at any time by pressing the [SET

LOCATE] button followed by the [LOCATE 0] button. This automatically switches the

TIME counter to Relative Time mode (if not already selected); the REL icon appears

to the left of the TIME counter. The counter will now read:

REL 0H 00M 00S 00
