C-change
deletes the marked program and allows the input of a new one. Illegal entries for date
and time is rejected and the process must be re-started.

Once all the programs have been entered, press
A-start
to begin the survey. The unit searches
through the programs until it finds the first to run. If the start time of the program has already
passed, the unit starts immediately. Otherwise, it displays:
SCREEN G13
050916
waiting for program 01
020503 07:00 020504 23:00
Where
050916
is the current time in hhmmss.
020503 07:00
are start date and time of the program
020504 23:00
are stop date and time of the program
When the start time is reached, the survey begins.
NOTE:
The start time indicates the beginning of the survey and NOT the time of the first
reading. Depending on the selected cycling rate the time of the first reading of the
file is delayed. Furthermore, to preserve the battery the GPS module is turned off
while waiting for a program start. If GPS is enabled, the unit turns on GPS and
waits for GPS lock and UTC synchronization. This further delays the time
required for the first reading.
At the stop time, the unit stops cycling, turns off GPS if enabled and closes the current file. If
another valid program is stored, the unit waits for its start time. When all the programs are
completed, the unit displays a "
press 1C
" message.
