If Your Batteries Ever Fail While Recording A Job, - Magellan MobileMapper Pro Manual

2. After opening a job for post-processing wait at least 10 seconds before logging
the first feature. Do not close the job until 10 seconds after recording the last
feature.
3. If your batteries ever fail while recording a job, replace them and open a new job
using the same feature library. When you download both jobs using the same
session of MobileMapper Transfer, they will be displayed together in the Map
Display area as an untitled job. Use the File > Save As function to give this
untitled job any name you wish and the result will be as though the batteries had
never failed. We recommend replacing the batteries when the receiver's Satellite
Status screen report that ~ 30% of the charge remains. Most rechargeable batteries
either will not supply sufficient voltage to power the receiver or will do so for
only a very limited time.
4. If possible, do not record more than about 2 MB of data into the same job – for
the same reason that you wouldn't work on a Word document for eight hours
without saving it at least a couple times. Instead, close the job and create a new
job with the same feature library. After you transfer the multiple files to
MobileMapper Office using MobileMapper Transfer utility, all of them will be
opened in the map display of MobileMapper Office as an untitled job (but only if
they were all recorded using the same feature library). By clicking File > Save
As, you can combine all of the data in a single job. You can also combine any
number of jobs, if all were created with the same feature library, by clicking File
> Import, selecting Job Files (*.mmj) in the Files of type field and browsing for
the job.
5. It takes twice as much time for electronic devices to access SD cards with twice
as much memory. This can affect performance, and MobileMapper Pro is not
immune to it. The maximum size SD card we recommend for MobileMapper Pro
is 128 MB. If you want to take more memory to the field, take more than one
card. Just remember to close any feature and then the job before you replace the
SD card.
6. Sometimes the SD card socket inside the MobileMapper Pro receiver becomes
loose and fails to hold the card tightly. When this happens data can be corrupted
on the card and essentially lost. When you try to download the corrupted file(s),
the receiver will display a "Data Card Loose" error message and MobileMapper
Office will be unable to download the corrupted data. A temporary work-around
is the place 1-2 cm of Scotch tape on the underside of the SD card just below the
9 copper contact strips. No part of any of these contacts should be covered with
tape. This will make the SD card fit more tightly in the receiver and prevent the
"Data Card Loose" error. Re-insert the card, reset the receiver (see Step A1) and
then format the card by pressing MENU > Card Utilities >Format Card.
