After Sales Booster Kit BSH–1 Technical Documentation Introduction General The Booster Kit comprises the following main items: Booster BSH–1; Mounting Bracket MBM–3; Front Cable SCE–2; Extension Cable SCE–3; and RF Extension Cable XRH–1. The Booster Kit upgrades the signal output level of the phone to that of a full–powered mobile ie approx. 3W. Note that only the Booster unit is covered in this booklet; the three cables and the mounting bracket are included under non–serviceable accessories.

The booster operates as follows.
After Sales Booster Kit BSH–1 Technical Documentation I/O Map EEPROM Contents The first sixteen (16) bytes carry the RF booster identification part (text string ” RF booster 1.0 ”), the next ten (10) bytes carry power level compensation values and the last ten (10) bytes, RSSI compensation values. When HFJ wants to read the contents of EEPROM, it has to disable the HOOK/SDA and TXI/SCL lines first. After 10 ms, read operation the lines will be back to normal.
Booster Kit BSH–1 After Sales Technical Documentation Power Level Control Circuit The pulse–width modulated control signal TXC is initially fed through a CMOS buffer D300 before being converted into a d.c. voltage by an RC filter network comprising R301, R302, C300 and C301. This analogue signal is fed through rectifier diode V603, and then to the non–inverting input of a comparator N300.
After Sales Booster Kit BSH–1 Technical Documentation Supply Voltage Circuits The supply from the vehicle battery is applied to connector X500. The voltage is first fed through a fuse, followed by suppressor V212 which protects the booster from overvoltages and transients. The voltage is then fed through a filter (L210, C213) eliminating potential interference generated by a vehicle’s electrical system (e.g. alternator).
