INTRODUCTION SCOLA provides hearing aid users with additional opportunities in difficult listening situations. The SCOLA FM system has been developed specifically for children and educational environments. These instructions therefore primarily address parents and teachers. The symbol refers to the section ‘Terms and definitions explained’, where you will find detailed explanations of functions and technical terms. WARNING This booklet contains important information and instructions.
THE SCOLA™ FM SYSTEM The SCOLA™ FM system consists of a SCOLA TEACH transmitter and one or two SCOLA receivers. The SCOLA TEACH transmitter’s primary function is to transmit sound signals from the microphone or audio equipment to the SCOLA receiver(s). The operating range is up to 20-30 metres, depending on the surroundings. The transmission power is very low and limited by national regulations. It has no physiological side effects.

With the charger plugged into the socket, connect the charger to the SCOLA TEACH as illustrated.
During charging the battery symbol will be shown in the display and the LED will be red. Battery charging! NOTE The transmitting function is off during charging. Connecting the microphone Plug the microphone lead into the microphone jack. The microphone lead serves as an antenna . For optimum operating range , make sure that the lead hangs as freely as possible. The standard version of the microphone is omnidirectional, which means that it picks up sound equally from all directions.
Positioning SCOLA TEACH can be placed in a pocket or clipped onto a belt. The microphone can be clipped onto clothes or hung around the neck on the neck cord. The standard microphone can also be replaced by one of the other microphones available as optional accessories.
OPERATING THE SCOLA FM SYSTEM On/off Press and hold down the on/off key on SCOLA TEACH for one second until the LED is green. The user’s name or ”WIDEX SCOLA” will appear on the display for approx. two seconds. SCOLA TEACH is turned off by holding the on/off key down for one second. Channel selection When SCOLA TEACH is turned on, the starting channel will usually be the channel last used, unless programmed differently. To select another channel : Hold down the or key.
NOTE Note that interference may occur if other transmitters are using the same channel as you. Synchronising SCOLA FLEX or SCOLA BUDDY If the receiving channel differs from the transmitting channel of SCOLA TEACH, the former can be synchronised to the latter. Press briefly. If there are one or more SCOLA receivers within a range of approx. 80 cm, the receiving channel will be synchronised to the transmitting channel (standard synchronisation ).
Microphone on/off The microphone can be turned on and off by pressing the on/off key briefly. A green light will flash in the LED and the following symbol will blink in the status bar: Keypad lock The keypad can be locked and unlocked by holding down the right and left arrow keys simultaneously.

GOOD ADVICE SCOLA TEACH is primarily intended for educational environments, but can also be used in other situations where noise, poor acoustics or the like make listening difficult.
Listening situation Use of SCOLA TEACH and microphone positioning In kindergartens / classrooms Ask the teacher to use SCOLA TEACH and position the microphone as described. Microphone types other than omnidirectional are available as optional accessories to optimise the speech signal. For group work, or if several teachers are present, we recommend the use of the Team Teaching function. This requires that SCOLA TEACH is provided with this function, and that an extra FM microphone is available.
CARE AND MAINTENANCE In general, the SCOLA™ FM system should be cared for in the same way as the hearing aid. It is a good idea to clean and remove dirt and debris from the FM system on a daily basis. There are also some special precautions which should be taken. • Remove any dirt from SCOLA TEACH with a dry, soft cloth. • Do not disassemble any of the SCOLA products or hearing aid, as this will void the guarantee. • Do not use water, alcohol or the like to clean the FM system.
WARNINGS Warning • Make sure that the batteries for the hearing aid and for the SCOLA TEACH are kept out of reach of children, who might place them in their mouths. • Discard used batteries carefully. • Do not change batteries in front of children, and do not let them see where you keep your supply.
IN CASE OF MALFUNCTION With proper use and maintenance, your SCOLA™ FM system will give you years of reliable service. The following pages contain some brief advice to follow if you experience problems with your SCOLA FM system.
If there is noise in the hearing aid, it could be because: • You are at or beyond the limit of the operating range of SCOLA TEACH. Reduce the distance between the SCOLA TEACH and SCOLA receiver. • Noise and whistling are interfering with reception, possibly because two or more FM transmitters are transmitting on the same channel as your receiving channel. To avoid this type of interference, make sure that only one FM transmitter is transmitting on the receiving channel. Try turning off your SCOLA TEACH.
If there is no sound from the audio equipment, but the sound from the SCOLA TEACH microphone signal is okay, it could be because: • The audio lead is not correctly plugged into the audio jack on the SCOLA TEACH or audio equipment. Check that it is correctly plugged in. • The signal from the audio equipment is too weak. Turn up the volume of the sound signal on the audio equipment’s volume control, if possible.
If the battery does not charge and the display does not indicate that the battery is charging, it could be because: • There is no power in the socket. Check that the socket functions. • The charger lead or jack is defective. Consult the hearing care professional where the SCOLA FM system was acquired. • The connecting terminals on the battery are dirty or defective. Consult the hearing care professional where the SCOLA FM system was acquired.
TERMS AND DEFINITIONS EXPLAINED Antenna The receiver and transmitter are both provided with an antenna. The microphone lead of SCOLA TEACH also serves as an antenna, and should therefore always be connected, even when only the audio input function is being used. Turn off the microphone if the microphone signal causes disturbance. Approval and CE marking SCOLA TEACH and the SCOLA receiver have been tested at an EU/FCC accredited test laboratory.
Battery - SCOLA TEACH One AA battery is required for SCOLA TEACH. The rechargeable battery included is a nickel-metal-hydride (NiMH) type battery. It is environmentally friendly and does not contain heavy metals. The contact surface at the negative pole ensures that only this type of battery can be charged in SCOLA TEACH. The lifetime of the battery depends on the number of times it is charged. If the battery is charged daily, we recommend changing the battery once a year to ensure optimum operating time.
warning If you use other types of rechargeable batteries in SCOLA TEACH than the original, it must be charged in a separate charger. If you use a NON-rechargeable battery, then use only high quality batteries, e.g. alkaline batteries. Always remove exhausted alkaline batteries from the battery compartment to limit the risk of leakage.
Battery charging Fully charging a drained battery takes ten hours. Before the battery is used for the first time, we recommend that it is charged for 14 hours. Even when the battery is fully charged, the battery symbol will continue to indicate that the battery is charging for as long as the charger is connected. The battery cannot be overcharged. warning Charger and mini USB connector: This device can be charged by an external charger or USB device.
When the battery is almost drained, the battery symbol flashes in the display and the LED flashes red. After a while, the transmitter will turn off. If the receiver is connected, this can be clearly heard in the hearing aid. For optimum battery lifetime, we recommend not recharging the battery until the battery indication is below two bars. Channels and frequencies SCOLA TEACH can be set to transmit on different channels. Each channel corresponds to a specific frequency.
SCOLA TEACH can transmit sound signals on most permitted frequencies in the frequency ranges 169 MHz– 176 MHz (H band), 180 MHz-187 MHz (J band) and 216 MHz-217 MHz (N band). note • Do not use two transmitters (e.g. SCOLA TEACH) on the same channel/frequency in the same area. • Note that there is a risk of interference from other radio communications, especially when using the system abroad. • Please note that when travelling abroad it may not be permitted to use the same channels as in your own country.
Teacher’s settings and Teacher’s synchronisation The SCOLA TEACH transmitter can wirelessly synchronise SCOLA FLEX with what we call the Teacher’s settings. These Teacher’s settings are temporary, and can only be reset by switching the hearing aid off and on. The purpose of this is to prevent small children from operating the mode switch and scan button on the SCOLA FLEX receiver during classes.
the transmitting channel, mode switch and scan button settings. When a Teacher’s synchronisation is performed within the reply range of 10 to 30 cm, the settings of the SCOLA FLEX will be shown in the SCOLA TEACH display. If a Teacher’s synchronisation is performed at a distance of approximately 30 cm-80 cm, the teacher’s synchronisation will still take place, and a beep-tone will be heard in the hearing aid.
If you have two hearing aids, they should both have a receiver. note Do not use SCOLA on aircraft or in hospitals without permission. Interference Interference occurs when signals from two transmitters on the same frequency are mixed in the same receiver. When the signals are equally strong, the interference will be most noticeable. The further away one transmitter is from the receiver compared to the other transmitter, the weaker the disturbing noise will be.
Microphones for SCOLA TEACH Omnidirectional lapel microphone: Standard microphone included with SCOLA TEACH. The microphone is equally sensitive to sound from all directions. The following microphones are available as optional accessories: Directional lapel microphone: Designed for noisy environments; more sensitive to sounds from one direction. Lavalier microphone: Hangs around the neck along with the SCOLA TEACH. The lavalier microphone lead also serves as an antenna.
Operating range The operating range of the FM system is highly dependent on the surroundings, including construction materials. The optimum operating range of 20-30 metres can be obtained in the open and with the microphone lead hanging freely. Inside buildings with steel and concrete walls and floors, the operating range may be reduced to ten metres. The position of the SCOLA receiver will also affect the range.
WARNING Audio connector (3.5 mm jack): The safety of the use of SCOLA TEACH is determined by any external equipment that is connected to the SCOLA TEACH via the audio connector. When SCOLA TEACH is connected to external mains-operated equipment via the audio connector, this equipment must comply with IEC60065, IEC60950, IEC 606011 or equivalent safety standards.
Additional technical information: SCOLA TEACH has a built-in FM receiver which enables Team Teaching. The channel used for the receiver and the team microphone must be the same. This channel can be selected in the Team Teaching menu. Reception on the Team Teaching channel is only possible if the frequency distance between the SCOLA TEACH transmitting channel and the Team Teaching receiving channel is sufficiently large. This distance is calculated by a program integrated in SCOLA TEACH.
WARRANTY A warranty of two years is provided. The warranty covers any defects in manufacture or materials. Defects arising from improper handling or repairs carried out by an unauthorised party are not covered by this warranty.
