SET UP INSTRUCTIONS
SET UP
There are many factors that can affect and/or interrupt the wireless UHF signal. These factors can
include walls, glass, metal objects, other solid surfaces, other digital or electronic devices
(CD/DVD/Media players, computers, laptops, Wi-Fi devices, cell phones wireless phones, two-way
radio communication devices and wireless remote controls), electronic appliances and people. Do
not install this equipment in a high temperature or high humidity environment. To ensure optimal
performance of the system, the working temperature should be between 23°F (-5°C) and 113°F (45°C).
Therefore, it is recommended to position the wireless receiver away from the above-mentioned
items and a minimum of 3.0 ft. (1m) above audiences and/or above ground level. To allow for proper
ventilation, the distances between equipment and objects around it should be no less than 8 inches
(200mm). Careful planning and testing of the selected installation location is critical to ensure
optimum and reliable wireless operation.
Note: In order to use two receivers (two sets of microphones) at a time, please use
two different frequency models. If using multiple models with the same frequency
range, please keep them at least 328 feet (100 meters) away from each other to
avoid signal interference.

MAINTENANCE GUIDELINES
DISCONNECT POWER BEFORE PERFORMING ANY MAINTENANCE!
CLEANING
Frequent cleaning is recommended to insure proper function, and an extended life. The frequency of
cleaning depends on the environment in which the device operates in: damp, smoky or particularly
dirty environments can cause greater accumulation of dirt and or debris in the tank. Clean the
external housing of the fixture at least every 20 days with a soft cloth to avoid dirt/debris accumulation.
NEVER use alcohol, solvents, or ammonia-based cleaners.
MAINTENANCE
Regular inspections are recommended to insure proper function and extended life.
There are no user serviceable parts inside these devices, please refer all other service issues to an
authorized ADJ service technician. Should you need any spare parts, please order genuine parts
from your local ADJ dealer or by visiting parts.adj.com.
To make sure the circuit contacts are in good condition and prevent overheating, a detailed review by
an approved electrical engineer every three months is recommended.
Be sure all screws and fasteners and mounting hardware are securely tightened at all times. Loose screws
may fall out during normal operation resulting in damage or injury as larger parts could fall.
Keep the unit dry. Avoid allowing moisture to enter any of the internal parts.
Electric power supply cables must not show any damage, material fatigue or sediments.
Damage could cause the device to fall and seriously injure a person(s).
