Back to Part 2 - First Impressions and Case design
Batteries and Power Supplies:
In part 2 of this review I complained about the design of the battery compartment in the Bushnell, which on reflection, was not entirely justified.
The battery cells are loadable without the cross bar being removed, as shown in Fig 11. It's still a
Acorn 6210 Internal cells are arranged as three
sets of four (Fig 12). Each set is isolated from and in parallel with the others. The external DC input is a fourth isolated circuit, also in parallel with the other three circuits.
The camera will operate with just four cells in any one of the circuits or an external DC power source of 6 to 12 volts plugged (see Fig 13) into the DC input socket. Use an external battery pack or a solar panel. The centre pin is positive polarity.
Be certain to observe the correct polarity, as indicated on the inside of the battery covers, when inserting cells
Because the circuits are isolated and in parallel, if any set of cells in one circuit is at a lower charge, they will not drain power from the other sets.
When all battery cells are removed the Acorn is able to retain time and date settings long enough to change batteries but with the Bushnell these will be lost. Keep one set of cells in place while you change the others to avoid having to reset the time and date.
Bushnell 119467 The arrangement of power circuits (see Fig 12a) is basically the same as the Acorn 6210 except that it can only use a 6 volt
external supply.
