Powering the MR277
6
1. Long press the Power button to switch the meter ON. The FLIR logo
will appear and the meter will proceed to power up. Long press again to
power OFF.
2. If the battery status indicator
shows that the battery voltage is low or if
the meter does not power ON, charge the battery by connecting the meter
to an AC charger using the supplied USB cable. When the MR277 is not
charging, the battery status indicator is only visible from the Main Menu
(press Select
to access the Main Menu). While charging, the battery
status indicator is always visible. Note that there is an indicator in the bot-
tom compartment, next to the USB jack, that illuminates when the MR277
is charging.
3. The meter switches OFF automatically after a programmed period of inac-
tivity (unless APO is set to OFF in the ‘Settings’ menu, see Section 5.8
Settings Menu for more information). Press any button to reset the APO
timer when you hear the three warning beeps. If no buttons are pressed
during the warning beeps, the MR277 will power OFF. To disable APO, or
to change the APO timer value, edit the APO parameter in the ‘Settings’
menu.
4. The internal battery is not user-serviceable. If you find that the battery will
not charge, see the Section 13.2 Battery Service for further instructions
and to learn about the proper charging techniques for when the meter is to
be stored for extended periods. Failure to follow these instructions can re-
sult in a battery that cannot be charged and that will require factory
service.
