RTU-292C Operations Manual

occasionally on voice peaks. Note that the PEAK indicator responds only to incoming radio
audio, not telephone audio.
The range of the RX Level Adjust control is about -40 dBm to +10 dBm. If the level from the
radio is outside this range, the correct level cannot be set using the RX Level Adjust control
alone, and it will be necessary to adjust the audio output at the radio itself until the correct level
is obtained.
NOTE
The proper operation and excellent performance of the RTU-292C will not be
obtained if the audio level from the receiver into the RTU-292C is not set correctly.
Excessive audio will overload the telephone line and equipment, causing distortion,
VOX falsing and poor hybrid operation. In addition, the telephone company may
cut off a call in progress, which contains audio high enough to bleed over into other
circuits.
