Talk Over
Talk over mode may be entered by pressing {5} while in audiometric testing mode.
There is no specific microphone ‘opening’; sound arrives at the microphone
through various openings in the cabinet (e.g., the slot in the side). Talk over
volume may be adjusted with the {▲}, {▼}, {►}, or {◄} keys. It is recommended
that a normal speaking voice be used at a distance of 1 to 2 feet, and volume
adjustment used to compensate for hearing status of the listener. Press {1},
{Menu}, or {Ο} to exit talk over.
Time and Date
The ES3 has a battery-backed up real time clock to maintain time and date. The
clock is set at the factory prior to shipment. See section Real-Time Clock Settings
for details on how to check or set the time and date. The backup battery is a
lithium rechargeable type and will be recharged whenever ES3 power is on.
Note: If the ES3 is not powered up for many months, the battery may become
discharged. In this case, the time and date will need to be reset and the instrument
should be left powered up for some time to recharge the clock battery. Normal
instrument usage is sufficient to keep the battery fully charged.
