HOOK.
OffHook
sets the level that the DC voltage on the telephone line must drop below for the VR240
to begin recording. The DC voltage on a telephone line is normally 48 volts. When a telephone
is lifted off hook, the DC voltage drops as a result of the load that the telephone puts on the line.
The OffHook circuit monitors the DC voltage and when the voltage drops below the threshold
voltage you have selected (0-63 volts in 1 volt steps), and if you have selected OffHook as the
channel configuration, the VR240 starts recording. The factory default is 32 volts.
