4.11 Flash Upgrade Switches - AEMC Simple Logger II User Manual

It is recommended to only press the RESET button when the logger stops
responding to a normal press button control when not connected to Data-
View . It is not recommended to reset the instrument when the logger is
®
recording, downloading or being configured.
If the logger is not responding to a button press, make sure the unit has
sufficient battery power. If the battery voltage is below 1.7V, the unit will not
respond to a button press. In this condition, pressing the RESET button
will not restart the unit.
It is recommended to download any desired session and erase the memory
before starting a new recording.
The resumption of the logger operation in the above situations assumes
that the RESET button cleared the fault(s). The logger will not resume
normal operation if the fault condition still exists. The instrument will try
to recover normally. However, under certain conditions, the clock and
memory full state may reset, meaning that the memory is marked as full
and the clock date/time is lost.

4.11 Flash Upgrade Switches

The Flash Upgrade Switches (see § 2.2.1 and 2.2.2 for reference to the
location) are used to recover from a failed flash upgrade.
Both switches should be turned to the "ON" position in order to flash
upgrade the instrument using the "Fail Safe" method of upgrade from
within the "SLIIFlashUp1xx" utility program.
Both switches MUST be set to the "OFF" position once the upgrade has
completed.
Failure to set both Flash switches OFF after the upgrade will prevent the
instrument from operating properly and deplete the batteries.
