Bench Testing / Programming; Battery Disconnect - Novatel MT 4000 User Manual

Bench Testing / Programming

After performing a firmware upgrade the device will respond that the firmware
load is complete. However, power must remain applied to the device for
approximately 2 minutes after the firmware upgrade completion message is
received. This allows time for the upgrade to be applied to the auxiliary
processor. The user can confirm it is safe to remove power by sending the
AT$OBDVER? command. If the upgrade is still processing, the device will
respond with an error. If the upgrade is complete, the device will respond with
the current software version.

Battery Disconnect

Use the MT 4000 Battery Disconnect Switch to remove battery power to the device (battery
models only). Move the switch toward the dot to turn the battery on. Move the switch away
from the dot to turn the battery off.
Place the power switch in the ON position before using the optional backup battery to
program or operate the MT 4000.
The figure below shows the MT 4000 Battery Disconnection Switch in the OFF position.
When transporting the device by air, move the power switch to the OFF position.
