* Estimated operating time assumes the use of a fresh 9 V alkaline battery (Duracell MN1604).
NOTE: The above battery life indicator readings apply for 9V alkaline batter- ies ONLY. Transmitter operating time for rechargeable 8.4V nicad batteries vary with type, brand and number of times the battery has been used. Actual operating times for rechareable batteries are not predictable.

TRANSMITTER AUDIO GAIN ADJUSTMENT (FIGURE 17)
or never on, the transmit audio level may require adjustment. Use the gain con- trols as follows to adjust the equipment for the best sound quality.
To adjust the audio gain, locate the transmitter audio gain control and use the supplied screwdriver to adjust the control.
•If the PEAK light is always on, decrease the audio gain by turning the gain con- trol counter±clockwise (while the vocalist is singing or the musical instrument is being played) until the PEAK light on the receiver flickers only occasionally.
•If the PEAK light is never on, increase the audio gain by turning the gain control clockwise (while the vocalist is singing or the musical instrument is being played) until the PEAK light on the receiver flickers only occasionally.

The receiver squelch control is factory preset at the 12 o'clock position for optimum performance. No further adjustment is normally required.
However, it is possible to adjust the squelch control to emphasize either signal quality or system range.

•To raise the squelch threshold, rotate the control clockwise. This causes the re- ceiver to demand a higher quality signal (less noise before muting), but it reduces the operating range.
•To lower the squelch threshold, rotate the control counterclockwise. This al- lows a lower quality signal through (more noise before muting), but it extends the operating range.
