the Plugs and reinsert them.

the Battery, where it connects to the Channel Support.
The Battery may not be charged. Check the voltage yourself or at a service station. If it is low,
charge it with a 12-volt, 1 to 2-amp trickle charger. If you do not use your machine for at least 45
minutes at a time, the Battery may need to be periodically charged. See the “Battery Care” section
in Chapter 4.
