limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial
environment. his 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.
his symbol is intended to alert the user to the
presence of uninsulated “dangerous voltage” within
the product’s enclosure that may be of sufficient
magnitude to constitute a risk of electric shock to
persons.
his symbol is intended to alert the user to the
presence of important operation and maintenance
(servicing) instructions in the literature accompanying
the appliance.
Caution: o prevent electric shock do not use this (polarized) plug with
an extension cord, receptacle or other outlet unless the blades
can be fully inserted to prevent blade exposure.
Attentions: Pour prévenir les chocs électriques ne pas utiliser cette

Application of The Antenna
Application of The Antenna (PA-1000BR ONLY)
- FM RECEIVING ANTENNA
The electric wave of FM broa casting is weakening in hills an valleys, aroun buil ings an in iron-
reinforce buil ings.
- INSTALLATION OF ANTENNA EXCLUSIVELY FOR FM
Listening to the broa casting, fix the antenna after eci ing the location an the irection so that the
reception may be optimize .
- INSTALLATION OF ANTENNA USING THE COAXIAL CABLE
Noisy reception may occur in built-up areas an factory sites as well as aroun power cables. This may
be the case even when an antenna is use exclusively for FM. In these regions, install the antenna using
75Ω coaxial cable.
- INDOOR ANTENNA
In the regions where FM broa casting is hear comparatively well ue to the near istance to the station
or woo en structure, you can receive broa casting of goo quality by using T-type antenna.(using
matching trans:300Ω/75Ω)
- AM LEAD ANTENNA
Fix one en of a six to eight metre length of vinyl-coate single cable to the AM terminal an the other
en to a high place like a wall.
- AM OUTDOOR ANTENNA
Install the vinyl-coate cable to an out oor place if the AM reception is not goo enough.
- AM LOOP ANTENNA
Connecting the fee er of the loop antenna of the terminal of 300Ω.
Listening to the broa casting, fix it after eci ing the location an the irection so that the receipt
con ition may be optimum.
