The Ringing Voltage Generator (RVG) measures roughly 3" x 5" x 1 3/4". It is totally self-contained and generates ringing voltage when the button is pressed. Ringing stops when the button is released or the phone is picked up (answered). This means that the operator determines the ringing pattern (series of rings and silence), but cannot, intentionally or unintentionally, ring the phone once the receiver is picked up. There is a frequency control that determines how fast the bell clapper strikes the bells. The current standard is 20 Hz; however, this adjustment can be used to operate older or foreign phones designed to ring at different frequencies. The frequency control can also be used to optimize the bell's sound or change its character. For example, a higher frequency can make a standard telephone sound British. The frequency control does not change the sound of electronic ringers. All connections (except AC Adapter) are made through a single 6-6 modular jack (RJ-11) on the front of the unit. Standard telephones are fitted with a 6-4 modular plug, which will mate with the 6-6 jack. By using a 6-6 modular plug, you have access to the unit's primary power and remote control lines. This feature offers a number of control options such as automated cueing or wireless control. Battery life is good enough to get most productions from tech through the final performance. In any event, Tele-Q will let you know when batteries are getting low. Power from the optional AC Adapter is applied through an electronic switch that always chooses the best power source. This means that if AC power fails, the unit automatically switches to battery operation, offering you a back-up source of power.
