Selection allows two microphone changes when accessories are
connected.
1. Talk Forward: Allows tester to provide instruction to the patient
while the headphones are in place. Increase/decrease the
volume by selecting the +/- (Figure 90). The lighted bar/VU
meter allows the examiner to monitor their voice for optimal
sound quality. When speaking, 0 is the optimal level.
2. Talk Back: Allows the tester to hear the patient through the
monitor headphone via an optional talk back microphone. The
talk back microphone must first be Enabled (Figure 90) prior to
setting the volume. The volume dial on the mic/monitor headset
must also be controlled for optimal volume.
