The unit turns off after it has been stopped for about

pack becomes too hot or too cold. The battery pack will not
work if this occurs. Use the unit at about 20 oC.

Release the hold mode.
If there is no response at all, the unit may have been

off and on again. Alternatively, turn the unit off, disconnect
the power source (AC or battery pack) reconnect the power
and turn the unit on again.
Condensation may have formed in the unit. Wait an hour for
