Integrator’s Note:
If a battery is installed
(on the CBR-4005B paddleboard or externally using the J8
connector), switch position 2 must be set to the Off position. If it is set to On, the battery will
discharge quickly.
If you don’t use a battery
, switch position 2 should be set to the ON position. Otherwise,
boot times could increase (by as much as 30 seconds in low temperature environments).
