TABLE OF CONTENTS

1. SAFETY PRECAUTIONS

• Before installation or use, be sure to carefully read all the instructions in this section in order to ensure long,
trouble-free operation.

• Be sure to follow all the precautionary instructions in this section, which contain important warnings
regarding safety.

• After reading, keep this manual handy for future reference.

Safety Symbol and Message Conventions

Safety symbols and messages are used in this manual to prevent bodily injury and property damage which
could result from mishandling. The conventions of the symbols and messages are described below. Before
doing anything else, read this section first so you are thoroughly aware of the potential safety hazards as well
as understanding the safety symbols and messages. Then before operating your equipment, read through the
instruction manual so you are familiar with its general operation.

• This is a class A product. In a domestic environment this product may cause radio interference in which case
the user may be required to take adequate measures.

• Use the unit only with the voltage specified on the unit. Using a voltage higher than that which is specified
may result in fire or electric shock.

• Install the unit only in a location that can structurally support the weight of the unit and the mounting bracket.
Doing otherwise may result in the unit falling down and causing personal injury.

• Only install the unit indoors. Installing the unit outdoors could result in the unit falling down due to
deterioration, possibly causing personal injury. Also, electric shock could result from the unit’s exposure to
rain.

• Should the following irregularities be found during use, immediately switch off the power, disconnect the
power supply plug from the AC outlet and contact your nearest TOA dealer. Do not attempt to further
operate the unit to avoid fire or electric shock.

• If you detect smoke or a strange smell coming from the unit.

• If water or any foreign object gets into the unit.

• If the unit falls or the unit case breaks.

• If the power supply cord is damaged (exposure of the core or cable disconnection, etc.).

• Never plug in nor remove the power supply plug with wet hands, as doing so may cause electric shock.

• Avoid installing the unit in humid or dusty locations, in locations exposed to the direct sunlight, or in locations
generating sooty smoke or steam as doing otherwise may result in fire or electric shock.

• Do not place heavy objects on the unit. Such object may fall or the unit may tip over, possibly resulting in
personal injury.

• Make sure that the volume control is set to minimum position before power is switched on. Loud noise
produced at high volume when power is switched on can impair hearing.

4. HANDLING PRECAUTIONS

• The Coxial Audio Adapter and the camera's microphone cannot be used simultaneously. If the camera has a
built-in microphone, turn off the microphone during camera video operation. If the camera is equipped with
an external microphone (C-A10MC), do not use the microphone during camera operation.

• When using multiple C-AP105 units, be sure to only connect Unit A to Unit B. The system will not operate
correctly if Unit A is connected to Unit A or Unit B is connected to Unit B.

• Use relays when controlling equipment that exceeds the unit's contact output capacity of 30V DC/10 mA.

• When permanently installing the Audio Adapter, do not place it on equipment that can generate excessive
heat (over 60°C), such as a camera drive or power amplifier.
