Switch between handset and the conference unit on 5324 phones Note that your handset must be onhook (i.e. you must be in speakerphone mode) to use the conference unit.Follow these steps to switch a call from the handset to the conference unit: 1 Press the key. This switches the call to the speakerphone.aking a second call on the 5304 phone To make a second call while on an active call, follow these steps: 1 Press any available Line Appearance key. This puts the active call on hold, and provides dial tone for a second call. 2 To make an internal call, dial the extension.
In general a surge is a transient wave of current, voltage or power in an electric circuit. In power systems in particular â and this is likely the most common context that we relate surges to â a surge, or transient, is a subcycle overvoltage with a duration of less than a half-cycle of the normal voltage waveform.urges are generally measured in microseconds. Every piece of electrical equipment is designed to operate at a specified nominal voltage such as 120 Vac, 240 Vac, 480 Vac, and so on.
Surge. Alternatively known as a line surge or power surge, a surge is a short, fast rise in voltage that inherently causes an increase in electrical current or vice versa. Exclusive to electrical circuits, a power surge can cause damage or impairment to a computer or other devices.For example, the standard voltage rating on a landline in the United States is 120V. If this rating is exceeded for more than three nanoseconds, it would be considered a surge, any shorter duration is a spike.Tip: Users can help prevent damage from power surges with surge protectors.or example, the standard voltage rating on a landline in the United States is 120V.
