The M175DC transmitter features a wide range input
limiter to guard against overload distortion and allow
maximum signal to noise ratio. The following procedure
will adjust the wireless system to take full advantage
of the limiter action to prevent excessive output level
from the receiver from overloading the recorder. This
will also maximize the signal to noise ratio of the audio
being recorded.

Note: This procedure assumes the receiver is
connected to an antenna and output connector
in the same configuration and under the same
load conditions that will be experienced in real
operating conditions.

1. Install battery in transmitter and attach microphone
and set transmitter MIC LEVEL Adjustment to near
maximum clockwise position.

2. Turn on transmitter and place microphone near a
sound source, such as a portable radio.

3. Ensure the receiver’s Power and Code LED indica­tors are glowing.

4. With the sound source (your portable radio) set
between stations, adjust its volume so that the 0 dB
Modulation LED on the receiver flickers slighty.

5. Leave the portable radio running and adjust the
receiver’s Audio Output Level Control so that the
audio input to the recorder is just below the maxi­mum that the recorder can handle.

Service and Repair

LIMITED ONE YEAR WARRANTY

The equipment is warranted for one year from date of purchase against defects in
materials or workmanship provided it was purchased from an authorized dealer. This
warranty does not cover equipment which has been abused or damaged by careless
handling or shipping. This warranty does not apply to used or demonstrator equipment.

Should any defect develop, Lectrosonics, Inc. will, at our option, repair or replace any
defective parts without charge for either parts or labor. If Lectrosonics, Inc. cannot
correct the defect in your equipment, it will be replaced at no charge with a similar new
item. Lectrosonics, Inc. will pay for the cost of returning your equipment to you.

This warranty applies only to items returned to Lectrosonics, Inc. or an authorized
dealer, shipping costs prepaid, within one year from the date of purchase.

This Limited Warranty is governed by the laws of the State of New Mexico. It states the
entire liablility of Lectrosonics Inc. and the entire remedy of the purchaser for any
breach of warranty as outlined above. NEITHER LECTROSONICS, INC. NOR
ANYONE INVOLVED IN THE PRODUCTION OR DELIVERY OF THE EQUIPMENT
SHALL BE LIABLE FOR ANY INDIRECT, SPECIAL, PUNITIVE, CONSEQUENTIAL,
OR INCIDENTAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE
THIS EQUIPMENT EVEN IF LECTROSONICS, INC. HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES. IN NO EVENT SHALL THE LIABILITY OF
LECTROSONICS, INC. EXCEED THE PURCHASE PRICE OF ANY DEFECTIVE
EQUIPMENT.

This warranty gives you specific legal rights. You may have additional legal rights which
vary from state to state.

If your system malfunctions, you should attempt to
correct or isolate the trouble before concluding that the
equipment needs repair. Make sure you have followed
the setup procedure and operating instructions. Check
the interconnecting cables.

We strongly recommend that you do not try to repair
the equipment yourself and do not have the local repair
shop attempt anything other than the simplest repair. If
the repair is more complicated than a broken wire or
loose connection, send the unit to the factory for repair
and service. Don’t attempt to adjust any controls inside
the units. Once set at the factory, the various controls
and trimmers do not drift with age or vibration and never
require readjustment. There are no adjustments inside
that will make a malfunctioning unit start working.

Lectrosonics’ Service Department is equipped and
staffed to quickly repair your equipment. In warranty
repairs are made at no charge in accordance with the
terms of the warranty. Out-of-warranty repairs are
charged at a modest flat rate plus parts and shipping.
Since it takes almost as much time and effort to deter­mine what is wrong as it does to make the repair, there
is a charge for an exact quotation. We will be happy to
quote approximate charges by phone for out-of-war­ranty repairs.

For timely service, please follow the steps below:

A. DO NOT return equipment to the factory for repair

without first contacting us by email or by phone. We
need to know the nature of the problem, the model
number and the serial number of the equipment. We
also need a phone number where you can be reached
8 A.M. to 4 P.M. (U.S. Mountain Standard Time).

B. After receiving your request, we will issue you a

return authorization number (R.A.). This number
will help speed your repair through our receiving
and repair departments. The return authorization
number must be clearly shown on the outside of the
shipping container.

C. Pack the equipment carefully and ship to us, ship-

ping costs prepaid. If necessary, we can provide
you with the proper packing materials. UPS is
usually the best way to ship the units. Heavy units
should be “double-boxed” for safe transport.

D. We also strongly recommend that you insure the

equipment, since we cannot be responsible for
loss of or damage to equipment that you ship. Of
course, we insure the equipment when we ship it
back to you.
