WATCH YOUR BATTERIES

When a receiver that usually is efficient in selectivity and distance work fails to perform in its customary way, look first of all to the "A" battery If it has become discharged it may have enough current to light up the filaments of the tube, but not enough to force off sufficient electron emission to work a distant, weak signal. Discharged ‘'B" batteries will also produce the same effect. Locals may come with apparently the same volume, because the energy from these stations is so great as to overcome the deficiency of the batteries, but the weak distant signal will be lost. Low batteries also broaden the tuning of the best and most sclective receivers.
