Bluetooth FM Transmitter
COMMON SENSE RULES FOR ALL USERS
1. The AC adapter supplied is designed for dry indoor use only. DO NOT use the AC adapter outdoors or in wet conditions. Shock injuries may occur.
2. Make sure the supplied antenna is connected at all times when transmitter unit is powered ON. This will prevent permanent damage to your unit.
3. For best results, try to find an open (unused) frequency to transmit on (http://www.radio-locator.com). Do not transmit on any occupied commercial radio
station frequency; for legal and ethical reasons. Refer to FCC guidelines for further guidance on proper frequency selection and operation.
4. Always follow your local regulations regarding the proper use of an FM transmitter. Most city, county, state governments provide a civil code online.
Contact local neighborhood association for rules on transmitter use within neighborhood (not all property is regulated by a neighborhood association).
5. Only use power adapters supplied with your unit. Using other types of power adapters may produce background noise with your transmitted audio and/or
could damage your unit. Contact your Fail-Safe distributor to purchase a replacement power adapter if yours becomes damaged or lost.
6. When transmitting from a microphone: only use a stereo plug microphone, using any other type of microphone such as a mono plug microphone will
permanently damage your unit; do not place microphone close to speakers due to resulting feedback (which may cause damage to transmitter).
7. Always ensure that proper antenna tuning methods were used. Placement of antenna is key to transmission quality. Inform yourself…this is only a guide.
8. Always disconnect Bluetooth when leaving the proximity of the unit. Leaving Bluetooth active may inhibit reconnecting or connecting other devices.
9. Do not set volume control to maximum (10) setting for initial adjustments. Start mid range (4-6) and adjust higher or lower as needed for quality.
10. Transmitter must be off when the memory card is inserted into the transmitter. Inserting card while transmitter is on may make transmitter inoperable.
This also applies to removing the memory card while power to the unit is on. Best practice is to only attach, insert, or remove while your unit is off.
FM Radio Transmission is a very tedious task and many variables factor into how clear your signal will be for any receiver. FS Electronics has made this unit
as “Plug and Play” ready as possible for customers. Proper operation still requires some basic knowledge of electronics and radio frequency transmission.
