1.2. About the SOLAR FM
The SOLAR FM is a unique FM transmission solution designed to operate in isolated areas with limited
electrical infrastructure, covering up to 10 km areas.
Capable of receiving audio from FM and satellite as well as analog and/or AES inputs, the system comes
complete with appropriate antennas and a dedicated smartphone application for control.
The standard system utilizes solar power with AC power back-up and wind power capability is available
as an option.
Designed to operate in harsh environmental conditions, the SOLAR FM can be easily deployed in
mountainous areas, forests and deserts. Once securely fastened to a mast, the user simply needs to
connect the energy input and audio sources and they are ready to broadcast!
1.3. Safety Precautions
This equipment complies with international mechanical and electrical standards. To maintain this
compliance, as well as to ensure proper and safe working conditions and avoid electrical shocks and fire
hazards, you must comply with the following recommendations:
The device should only be utilized in the conditions described in the user manual.
The device is designed for industrial usage and must only be operated by qualified personnel.
The device may be heavy; it must be lifted and handled with care, specifically during unpacking
and set up.
Electrical precautions
Unplug from mains outlet before any intervention.
Any maintenance, adjustment or repair must be carried out by personnel specifically trained by
WorldCast Systems.
Before switching on the device, make sure the nominal voltage specified on the device matches
the mains nominal voltage.
The device should only be operated on a stable electrical network. If the electrical network is not
stable, a power conditioner, such as a UPS, must be used
The device must only be used with a plug that incorporates a protective ground contact.
To avoid any risk of electrocution, the protective earthing conductor must not be cut,
intentionally or accidentally, either on the device or on the power cord.
High quality shielded cables are mandatory.
Environmental precautions
It is necessary to verify that environmental conditions comply with those recommended in the
manual.
Nothing must obstruct the ventilation.

To avoid any electromagnetic interference, the device must only be used when it is closed,
installed in a cabinet and connected to the earth as per the instructions.
The device should not be exposed to dripping or splashing and no objects filled with liquids, such
as coffee cups, should be placed on the equipment.
Connectors may be hot on high power units.
Precautions regarding the lithium battery and the NiMH battery
This device includes a lithium battery and an NiMH battery.
Do not puncture the batteries
Do not throw the batteries in fire
Do not immerse the batteries in water
Do not throw away the used batteries, recycle them instead. You may send them back to us if
needed.
Lithium battery
If the battery is not correctly replaced, there is a risk of explosion.
Only replace it with a battery of the same type. Contact us before attempting to use another type
NiMH battery
If the battery is not correctly replaced, it may damage the equipment.
Only replace it with a battery of the same type and after having contacted the WorldCast Systems
support team.
Practices to follow to extend the life of the battery:
When not in use, store in a place with a stable ambient temperature between +10°C et +25°C.
When stored, unplug the battery from the equipment.
Make sure the battery is never completely empty when stored. We recommend charging it once
a month while in storage.
If these precautions are not followed, the guarantee will be void.

2. RECOMMENDATIONS
2.1. Storage
!Storing the SOLAR FM for a long period may lead to a complete discharge of the battery and to its
deterioration. If a long storage time is required, reload the battery using solar panels or a
stabilized lab power supply before it is discharged.
The frequency for recharging depends on the storage temperature:
Every 250 days if stored between 20 and 30°C
Every 100 days if stored between 10 et 20°C
Every 30 days if stored between 5 and 10°C or between 30 and 35°C
2.2. Installation
2.2.1. SOLAR FM bindings
The SOLAR FM is a system which operates outdoors.
We recommend you set it up on a pole (or pylon) with the supplied frame.
!We recommend you do not set it at the bottom of the pole to limit the risks if defacing, theft…
On flat ground, WorldCast Systems recommends installing the transmission antenna about 10 meter high
in order to best cover the area. Other elements can then be installed at a lower height and connected
using supplied cables.
For urban installation, the transmitter will be set higher than the highest potential obstacles (trees,
buildings,…)
2.2.2. Electrical recommendations
!Before any handling of the system, disconnect the battery and the mains from the transmitter.
!When installing, make sure to connect all elements before starting up.
Starting the unit before all cabling operations are completed could lead to damage of the various
stages of the system.

2.2.3. Solar recommendations
2.2.3.1. Installing the solar panels
WorldCast Systems supplies solar panels required to operate the SOLAR FM. You may however use other
panels.
Be careful to not select oversized solar panels which could be detrimental to the proper working of the
transmitter. Use solar panels with specifications matching those of panels supplied by WorldCast
Systems (see chapter 3).
Depending on the installation zone (longitude, latitude), it is essential to correctly position the solar
panels to insure the best performance.
Two parameters need to be checked:
The orientation
The inclination
The best orientation depends on the latitude:
Installation north of the Equator (Northern Hemisphere): panels must be oriented towards the
south.
Installation south of the Equator (Southern Hemisphere): panels must be oriented towards the
north.
Once the orientation is set, the inclination of the solar panels must be set in order to obtain the best
possible efficiency.
For optimal efficiency, panels must be perpendicular to sun rays when the sun is at its highest point.
To find the right position according to your location, a sun position calculator is available at
http://www.solartopo.com/solar-orbit.htm..

2.2.3.2. System maintenance
As an outdoor system, the SOLAR FM requires heavier maintenance than an indoor system.
It is therefore essential to:
Clean the solar panels at least once a year to insure their efficiency,
Change the NiMH battery every three years to maintain the initial transmission potential.
!Warning: the SOLAR FM includes a battery management system designed to optimize the battery
charge and discharge.
To replace it with a battery not approved by WorldCast Systems may lead to a dysfunction of the
unit which would not be covered by the warranty.
!Never allow the NiMH battery to be completely empty.
2.2.4. RF recommendation
The SOLAR FM includes reception and transmission antennas.
Make sure each is properly installed. Please refer to the installation documentation for each antenna.
