Firmware Update Using a Pre-programed mini SD Card
Firmware Update Basics
You will need a pre-programmed 500MB-2GB mini SD card to update
your telescope's firmware. Alternatively, a 500MB-2GB micro SD can be
used in conjunction with a mini SD adapter card.
NOTE: You can also program your own mini SD card using the Meade
Autotostar Updater (ASU) software that can be downloaded
from the Meade Instruments website.
We strongly recommend that you always update the LightSwitch telescope's firmware via a 500MB-2GB
mini SD card as outlined in this document and not via a PC. Other capacity SD cards will not work.
Instructions
1.
Use a reliable power supply.
2.
Ensure that your Meade LS telescope is switched off.
Insert the pre-programmed Mini SD card supplied into the telescope's mini SD slot as described
3.
under the Inserting the mini SD Card heading in this document.
4.
Switch ON the telescope and wait for around 10 seconds for the hand box to respond. Then follow
the instructions on the hand box display.
5.
Wait for approximately 30 minutes for the firmware to be updated.
6.
Do not remove the mini SD card or switch off the telescope while updating the firmware or the
telescope may need to be returned back to Meade Instruments Inc. for re-flashing.
7.
The AutoStar III handset will confirm that the software has been updated.
8.
Switch OFF the telescope.
9.
Remove the Mini SD card from the telescope.
10. The firmware update is now complete.
CAUTION:
Do not plug or unplug the power supply or handset to/from your telescope while the
telescope's ON/OFF switch is at the ON position.
Inserting the mini SD card
Slowly press the mini SD card into position making certain that the mini SD card is not at an angle when
inserted. If the mini SD card is at an angle or facing the wrong way it will stop half way and you will be unable
to push it into position. Finally, push the mini SD card in all the way so that it 'clicks' in place.
Note that once you switch ON the telescope with the mini SD card inserted, the red power LED should remain
switched on. If the telescope is unable to read the mini SD card for any reason, the red power LED will flash
intermittently for a short period of time and/or the handset display will remain blank. If the update starts but
takes too long to complete (typically over 30 minutes) the files on the mini SD card may have been corrupted.
Note that in some cases, leaving the telescope switched on overnight may still complete the update.
CAUTION:
Please make certain that when you insert a micro SD card into a mini SD adapter this is
done with care. In rare cases, it is possible that the contacts in the mini SD adapter end
up over the top of the micro SD card rather than below.

Please observe the correct orientation of the mini
SD card when inserting it into the mini SD slot on
the telescope.
It is important that you do not force the mini SD card
into the slot.
