Tone Ringer For Telephone Set

( NOT E 1 ) Supply initiation voltage is the value of DC supply voltage required to start the tone

ringer oscillation.

( NOT E 2 ) Sustaining voltage is the value of DC supply voltage required to maintain oscillation.

( NOT E 3 ) Oscillator frequency is determined by the following equations :

fL = 1 / ( 1.234 * R1 * C1 )

Hz

fH1 = 1 / ( 1.515 * R2 * C2 )

Hz

fH2 = 1.24 * fH1

Hz

( NOT E 4 ) Ringing start voltage is the value of AC supply voltage required to start the tone ringer

ringing in FIG.3

( NOT E 5 ) T his product is not designed for protection against radioactive rays.

( NOT E 6 ) All data and specifications are subject to change without notice.
