9、ms 10 Watt I This receiver is equipped with a neon lamp on the dial scale which indicates the condition of the batteries. The neon lamp is included in an oscillating (R-C) circuit which has been designed to oscillate at approximately 3 pulses per second when the batteries are in a fully charged cond

10、ition. As the battery voltage decreases with use the number of pulses per second decreases. When the battery voltage is low (approximately 72 volts) the light flickers more slowly (approximately 1 a second). The set should not be operated from battery power after this point is reached. The batteries

11、 should be charged for at least twice the time they were usedas soon as possible after they have been run down. COMPILED BY M. N. BEITMAN.

12、r voltage dividing net work and filter is incorporated in this receiver. The circuit is arranged to provide a very light charging current when the receiver is operated from either AC or DC. This is just enough to maintain the batteries but will not charge up used batteries. A separate charging posit

13、ion is provided for rapid recharging of the bat teries. The resistance voltage divider is designed to give a charging rate oi approximately one third the dis charge rate, this having been found to give best results. It is recommended that the batteries be left on charge at least twice the time they were used. As the bat teries age it is necessary to charge for a longer period. 145 收音机爱 好者资料库 RadioFans.CN
