3.0 ADJUSTING THE TIME SETTING
3.1 Clock Setting For Units Without Real Time Clock (RTC)
Changing the displayed time, which corresponds with the real time internal clock setting of the tachograph, can only be carried out with the
drawer in the OPEN position. The tachograph must then be switched to a Time Adjust mode, which is achieved by pressing the Mode
Change push-button (
O
) for more than 3 seconds. In this mode, the Mode Change push-button (
O
) is used to switch between the various
time fields while the Advance push-button (
) is used to increase the displayed value in the current field. When Time Adjust mode is first
selected the hours (left-hand) field flashes and can be adjusted by momentarily pressing the Advance push-button (
) [for an individual
increment] or continuously pressing the Advance push-button (
) [for larger alterations] until the required value is shown in the field. This
procedure is repeated for the other five fields, which alternate between left hand and right hand until all six fields are set, at which time the
current set time is displayed. This setting procedure is shown in tabular form below.
