Nady Systems ENC Duet, Owner'S Manual

1. Unscrew the 

BATTERY COMPARTMENT COVER (17)

 and remove, exposing the

BATTERY HOLDER (18)

. Insert a fresh 

9V ALKALINE BATTERY (19)

, observing the 

correct polarity as marked, and screw the cover back on to the microphone. 

Make sure the cover is screwed on completely. A fresh alkaline battery can 

last up to 16 hours in use, but in order to ensure optimum performance, it is

recommended that you replace the battery after every 10 hours of use.

2. Turn on the WHT by sliding the 

OFF/STANDBY/ON SWITCH (20)

 to the STANDBY 

position (transmitter on, audio muted) or the ON position (transmitter and audio

both on). The 

BATTERY INDICATOR LED (21)

 will give a single quick flash, indicating

usable battery strength. In the case of a dead or low battery, the LED will either 

not go on at all or will stay on continuously, indicating that the battery should be 

replaced with a fresh one. To preserve battery life, turn the transmitter off when 

not in use.

3. The microphone is now ready to use. Most or all of the 

RF LEVEL DISPLAY LEDs (4)

on the Enc

-

DUET receiver should now be lit, indicating a received signal 

from the transmitter. When ready to speak, slide the transmitter switch to the ON 

position. Adjust the volume of the receiver as per the Audio Output Microphone

Connection section of the above Enc

-

DUET receiver instructions. The 

AF LEVEL LED 

DISPLAY (5)

 on the Enc

-

DUET receiver will light up to 5 LEDs (4 green and 1 red)

for all input signals. Occasional flickering on and off during use of the 

top red LED indicator in this display is normal, however if the red LED stays on 

continuously, it means the signal is too loud and there is the possibility of overload 

distortion. Back off from the microphone until the red LED indicator only flickers 

on peaks. 

[Note: Observe care in selecting P.A. volume, transmitter location and speaker 

placement so that acoustic feedback (howling or screeching) will be avoided.]
[Note: Microphone elements can easily be destroyed by the buildup of salts and 

minerals from perspiration and saliva. It is good practice to put a windscreen on 

the mic element at all times to protect it.]
