4. OPERATING INSTRUCTIONS

The generator provides special pulses which may be fed to the audio system to be tested either by the in- built speaker or via the output connector, the level of this may be adjusted by the level control. The speaker output level is fixed.

Once this signal has been fed through the system under test, the receiver will be able to indicate whether the received signal is in phase or out of phase, the appropriate LED (IN-PHASE or REVERSE) will flash at the speed of the pulse. The signal may be fed into the receiver by one of three methods, this is determined by the INPUT-MODE switch.

•Selecting INT uses the built in microphone.

•Selecting EXT allows an external microphone to be used.

•Selecting LINE allows a line level signal to be used.

Note: The unit does not provide phantom power for a microphone input.
