Power Control and Charging
To turn on the MESA unit, ensure that a charged battery is in the unit or connect the supplied AC
adapter and press and hold the power button (see page 8) until it begins flashing. During operation, to
turn off the MESA unit, press and hold the power button until the "Power Off" graphic appears on the
screen.
Press and hold the power button for 8 seconds or more to perform a firmware reset. This method
should only be used if the unit has locked up and the normal shutdown method is not functioning.
The MESA unit has a built-in battery charger. The MESA
unit will automatically begin charging an inserted battery
if the AC adapter is connected. Plug the AC Wall adapter
into the power outlet and then plug the connector into
the port labeled "Power" on the top of the MESA.
Note: If the operating temperature of the unit is elevated,
above 37 degrees C, the battery charging will not begin
until the temperature drops below 37 degrees C.
Note: It is recommended that the MESA battery be
recharged regularly during extended periods of storage (3
months or more) to prevent damage to the battery.
Additionally, when storing the MESA for long periods (1
month or more), it is recommended that the battery be
removed from the unit and placed in the storage
compartment in the case. Storing the MESA with the
battery in the unit can deplete it more rapidly, potentially
shortening the life of the battery.
