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.

Same Day Shipping Cutoff time
Online orders received by noon Eastern time typically ship the same day. If your delivery due date is critical please note your due date in the order messages at checkout, and then contact us.
Why Noon? Well, while we stock quite a few items in our warehouse, many items we have dropshipped by our vendors. They need time to process the order, so to ensure that we can get the order to the vendor and give them enough time to ship it out the same day, we need to get the order to them as early as possible in the day.
Please also note that the shipping rates for many items we sell are weight and dimension based, as this is the method that FedEx and UPS use to rate the package's cost to ship.
We understand things happen and items occasionally need to be returned. To make things as hassle-free as possible, we have dedicated pages about our Returns Policy (what’s eligible to be returned) and our Return Process (how to go about returning eligible items)
