Operating well below receiving frequencies producing blank-spots on frequency tuning range. There are available 24 Volts Band Expanders, also most 24 Volts vehicles have a 24 Volt to 12 Volt converter to run the stereo system.Ĭommon to all FM Band Expanders are Radio Station Double-Ups caused by shifting 20Mhz of bandwidth into 14Mhz of bandwidth ( 88Mhz to108Mhz shifted into 76Mhz to 90MHz ) and overlapping Japanese band FM Band and International FM Band ( 88Mhz to 90Mhz ) eg: Radio Station 105.4Mhz and 95.4Mhz will both tune into the car radio at 85.4Mhz.Ĭommon to all Band Expanders frequency harmonics generated by Crystal oscillator.

Is it important to run Band Expander on 12 Volts?īand Expander is designed to run on 12 Volts. Listed below are a number of frequently asked questions.ġ.

Note: The display number on the radio unit will not be changed. Please ensure the unit is clear of any moving pedals, heater controls etc. If your vehicle is fitted with a Diversity antenna system connect the Band Expander to the main aerial and disconnect the sub - aerial, but we recommend fitting a Band Expander on each aerial input. NB. Your FM Band Expander is earthed via your existing antenna. Preferably use theĪccessory feed that supplies the radio. Your car using the black quick tap connector supplied. Connect the red power lead from the FM Band Expander to +12 volt power supply on

Plug the male plug from the FM Band Expander into the antenna socket on the radio.ĥ. Plug the antenna lead into the female socket on the FM Band Expander.Ĥ. Disconnect the antenna lead from the back of your car radio.ģ. Remove radio from dash or obtain clear view of antenna input socket to radio.Ģ. To obtain maximum efficiency from your unit please follow the simple installation instructions below:ġ. The supply for 12V DC (+) voltage to the red wire, negative to the black wire It attaches in-line with the antenna input on the stereo and will receive all stations from 88Mhz to 108Mhz, different from Japan radio frequency from 76Mhz to 90Mhz. It achieves this by shifting the transmission frequencies into the band that the Japanese radio will detect. The radio band expander enables the orignal equipped radio in Japanese imported cars to receive radio transmissions in other countries.Įlectronic circuit with both active and passive connections. Shift the Japanese version in line with the wave band universal Japanese car
