magnitude to constitute a risk of electric shock to
persons.
This symbol is intended to alert the user to the
presence of important operation and mainte-nance
(servicing) instructions in the literature accompanying
the appliance.
* Do not install this equipment in a confined space such as a book case or similar unit.
* The apparatus shall not be exposed to dripping or splashing and no objects filled with liquids, such vases, shall be placed on the apparatus.
* Worded: “WARNING FOR YOUR PROTECTION PLEASE READ THE FOLLOWING-WATER AND MOISTURE: Unit should not be used
near water(e.g. near a bathtub, washbowl, kitchen sink, laundry tub, in a wet basement, or near a swimming pool, etc).
Care should be taken so than objects do not fall and liquids are not spilled into the enclosure through openings.”
Service Instructions
* Worded: "Caution: These servicing instructions are for use by qualified service personnel only. To reduce the risk of electric shock, do not
perform any servicing other than that contained in the operating instructions unless you are qualified to do so."
* Location: Instruction Manual.
NOTE : This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to
cause harmful interference in which case the user will be required to correct the interference at his own expense.
Attentions: Pour prévenir les chocs électriques ne pas utiliser cette
fiche polarisée avec un prolongateur, une prise de courant
on une autre sortie de courant, sauf si les lames peuvent
étre insérées à fond sans en laisser aucune partie à
découvert.
To prevent fire or shock hazard, do not
expose the unit to rain or moisture.
WARNING
CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK.
DO NOT REMOVE COVER (OR BACK).
NO USER-SERVICEABLE PARTS INSIDE.
REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.

Installation Environment
Important Safety Instructions
- Avoid excessive heat, humidity, dust and vibration
Keep the unit away from locations where it is likely to be exposed to high temperatures or humidity-such as
near radiators, stoves, etc. Also avoid locations which are subject to excessive dust accumulation, or to vibration
that could cause mechanical damage.
- Avoid physical shocks
Strong physical shocks to the unit may cause damage. Handle the unit with care.
- Do not open the case or attempt repairs or modifications yourself
This product contains no user-serviceable parts. Refer all maintenance to qualified Thinuna service personnel.
Opening the case and/or tampering with internal circuitry voids the warranty.
- Always power off before making connections
Always turn the AC mains OFF before connecting or disconnecting cables. This is important to prevent damage
to the unit itself as well as other connected equipment.
- Handle cables carefully
Always plug and unplug cables (including the AC mains power cord) by gripping the connector, not the cord.
- Clear with a soft dry cloth
Never use solvents such as benzine or paint thinner to clean the unit. Wipe clean with a soft, dry cloth.
Installation this system is not difficult and complex. But you still need to spend some time to read this manual
and ensure the connection and installation is exact.
Never place this product in an environment which could alter its performance or reduce its service life.
Such environments usually include high levels of heat, dust, moisture, and vibration.
1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
5. Do not use this apparatus near water.
6. Clean only with dry cloth.
7. Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.
8. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus
(including amplifiers) that produce heat.
9. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades
with one wider than the other. A grounding type plug has two blades and a third grounding prong.
The wide 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.
10. Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and
the point where they exit from the apparatus.
11. Only use attachments/accessories specified by the manufacturer.
12. Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the
apparaus. When a cart is used, use caution when moving the cart/apparatus combination to avoid injury
from tip-over.
13. Unplug this apparatus during lightning storms or when unused for long periods of time.
14. Refer all servicing to qualified service personnel. Servicing is required when the 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.

7. FM ANTENNA TERMINALS
The FM terminal accepts a 75 Ohm Coaxial cable that
terminates at an FM antenna. Antenna position may
affect performance so it may be necessary to
reposition the antenna for the best reception.
Note: The ability to receive an FM signal may be
diminished by terrain, area buildings, and the
construction materials of the building housing the
receiver. Keep these circumstances in mind when
selecting the type of FM antenna and its mounting
position.
An indoor FM antenna is provided and should be
suitable for most applications. Repositioning the
antenna may be necessary to identify the optimum
mounting location. If greater signal strength is required,
replace the supplied antenna with a large outdoor FM
antenna using 75 Ohm coax as the lead wire.
