- Notes
-
There are six models in this series. The later "A" models added a "B" Battery Saver slide switch, located in the upper right corner of the speaker grill. The two slide switch positions are: left (DISTANCE-HI), and right (LOCAL-LO). The DISTANCE-HI position increased the "B" battery drain and improved reception for long distance broadcasts. The original model "B" battery drain was fixed at the later "A" model DISTANCE-HI drain level.
