TRANSMITTER SETUP AND CONNECTIONS
T2 or EC2 Hand–Held Microphone-Transmitter
1. Make sure the transmitter POWER ON/OFF switch is in the OFF position.
2. While holding the upper part of the transmitter, unscrew the handle and slide it
downward, as shown below in Figure 3.
3. Insert a fresh 9 V alkaline battery into the compartment, observing proper battery
polarity. Then close the handle.
IMPORTANT: Use 9 V alkaline or heavy-duty, rechargeable 8.4 V nicad batteries
only. Carbon–zinc and zinc–chloride batteries are not recommended.
T1 or EC1 Body-Pack Transmitter
1. Press down on the OPEN side of the battery compartment cover and slide it in the
direction indicated until it flips open, as shown in Figure 4.
2. Insert a fresh 9 V alkaline battery. Make sure the battery polarity (+/–) is correct.
Close the compartment cover.
3. Plug the connector end of the lavalier microphone cable into the 4–pin connector
on the transmitter. See Figure 5.
4. If you are using a lavalier microphone, either press it into the mounting block and clip it
to your tie or lapel, or mount the microphone with a sew–on mounting clip.
5. Attach the transmitter to your belt with the belt clip.
OPERATING THE SYSTEM
1. Slide the receiver POWER switch to the ON position. The POWER/RF light on the
receiver will glow green.
2. Move the transmitter POWER and MIC switches to the ON position. If the battery is
fresh, the green POWER light on the transmitter will glow.
3. Verify that the POWER/RF light on the receiver changes from green to orange and
glows steadily. This indicates that the transmitter signal is being received.
NOTE: A flickering light indicates marginal operation.
4. Talk into the microphone and verify that the red AUDIO PEAK light on the receiver
flickers only on loud peaks. If necessary, adjust the audio gain settings according
to the procedure in the Audio Gain Adjustment paragraphs.
5. If monitor headphones are to be used, turn up the headphones VOLUME control
so that the transmitted audio signal is heard. The headphones level may require
adjustment after the transmitter audio gain is adjusted.
6. While speaking into the microphone, move around the performing area and make
sure the area is free of interference and “dead” spots.
7. When the performance or presentation is over, slide the receiver and transmitter
POWER switches to the OFF position to conserve battery power.
NOTE: Use the MUTE switch to turn the transmitter off and on during a perfor-
mance or presentation. This prevents “popping” or “thumping” noises that can oc-
cur when the power is turned on and off.
Audio Gain Adjustments
If the AUDIO PEAK light glows constantly, the audio signal is too high and may be
distorted. If the AUDIO PEAK light never glows, the audio signal is too low and may
be noisy. To correct these problems, adjust the transmitter as follows:
S T1, T2, EC1 (Figures 6, 7): Using the supplied screwdriver, adjust the audio lev-
el control on the transmitter until the receiver’s AUDIO PEAK light flickers occa-
sionally in response to a typical audio signal.
S EC2 (Figure 7): Unscrew the handle on the hand-held transmitter and locate the
audio GAIN switch next to the battery holder. Select either the LO gain or HI gain
position so that the receiver’s AUDIO PEAK light flickers only occasionally in
response to a typical audio signal.
