IMPORTANT SAFETY INSTRUCTIONS !
READ these instructions.
KEEP these instructions.
2.
HEED all warnings.
3.
FOLLOW all instructions.
4.
DO NOT use this apparatus near water.
5.
CLEAN ONLY with dry cloth.
6.
DO NOT block any ventilation openings. Install in accordance with the manu-
7.
facturer's instructions.
DO NOT install near any heat sources such as radiators, heat registers, stoves,
8.
or other apparatus (including amplifiers) that produce heat.
DO NOT defeat the safety purpose of the polarized or grounding-type plug. A
9.
polarized plug has two blades with one wider than the other. A grounding type
plug has two blades and a third grounding prong. The wider blade or the third
prong are provided for your safety. If the provided plug does not fit into your
outlet, consult an electrician for replacement of the obsolete outlet.
PROTECT the power cord from being walked on or pinched, particularly at plugs,
10.
convenience receptacles, and the point where they exit from the apparatus.
ONLY USE attachments/accessories specified by the manufacturer.1.
11.
UNPLUG this apparatus during lightning storms or when unused for long periods of
12.
time.
REFER all servicing to qualified service personnel. Servicing is required when the
13.
apparatus has been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus
has been exposed to rain or moisture, does not operate normally, or has been
dropped.
DO NOT expose the apparatus to dripping and splashing. DO NOT put objects filled
14.
with liquids, such as vases, on the apparatus.
15.
Remove the batteries from the receiver if the system will not be used for a long
period of time. This will avoid any damage resulting from a defective, leaking
battery.
16.
DO NOT throw used batteries into a fire. Be sure to dispose of or recycle used
batteries in accordance with local waste disposal laws.

Channel Selection: Press the "SELECT" button to increase the channel number by one
(0-9, then A-F).* Press the ASC button, and the Channel Display will begin to flash. Hold the
transmitter’s (HH38 or MBP38) IR window towards and in close proximity less than 1.5 ft. to the
ECD receiver’s IR window. The ECD receiver’s RF Signal LED will light once
5
synchronization has been established. Only one IR connection can be established at a time
during each syncing process.
*Note: If the RF light on the receiver is on when the transmitter is off, change to another channel.
Receiver volume control:
Rotate the audio output level control knob to the left to reduce the output level, rotate to the right
to increase the output level.

Tips for Improving System Performance
Tips for Improving System Performance
Maintain a line of sight between transmitter and antenna.
Avoid placing the receiver near metal surfaces or any digital equipment (CD players, computes, etc)
Keep the receiver away from the wall and over 3ft. from the ground
Cellular telephones, two-way radios and other RF sources can interfere with the transmitting
frequencies. Maintain the greatest distance possible from the interfering equipment to minimize
interference.

Turn on transmitter,
Make sure the +/- indicator on the batteries

Control up, adjust the Gain switch on the
transmitter, Check the power connection of
the receiver and amplifier or mixer
Move the receiver away from metal objects,
Check whether there is an obstruction
between receiver and transmitter,
Move the transmitter near the receiver,
Re-Sync receiver and transmitter
to the same frequency
Change the batteries the in transmitter
Remove nearby sources of RF interference (CD players, computers, digital
effects, in-ear monitor systems, etc.)
Replace transmitter batteries
