    							- 11 -  Appendix E.  Frequently Asked Questions (FAQ) 
    Below is a list of questions we have been asked 
    over and over again, together with the standard 
    answers supplied. 
     
    1. My converted FM1200 does not generate 
    tones, how come? 
    Step through the Status Menu (H-5). If you see: 
    Tone CPU not active, you have either made an 
    error in mounting the tone system PROM (32-pin 
    PLCC 27C256R), or the wire link next to the tone 
    CPU is not set to the ground position. Check 
    your solder work carefully using a continuity 
    tester. 
     
    2. Is it possible to omit the tone PROM, it 
    seems such a hassle to mount! 
    Sure, but you will be unable to use any of the 
    functions that require tone processing (DTMF, 
    CTCSS, 5-tone calling, 1750 Hz, etc.). 
     
    3. Can I use the FM1200 70cms for 9k6 packet 
    radio? 
    We are not packet radio users but were told that 
    9k6 is not possible because the varicap-based 
    automatic RF tracking system inside the FM1200 
    will faithfully counteract any frequency change 
    beyond normal deviation caused by modulation 
    signals. 1k2 packet radio is possible without 
    problems using a modem hooked up to the 
    microphone connector. 
     
    4. Other stations tell me my deviation is too 
    low, how can I adjust it? 
    They are probably listening in 25 kHz bandwidth. 
    If yours is an S FM1200, (examine the type 
    number) then you can rely on it that the peak 
    deviation has been accurately set to ±2.5 kHz by 
    the factory, as required for 12.5 kHz channel 
    spacing. Similarly the R radio will produce ±4.0 
    kHz peak deviation, and may in rare cases 
    require some reduction if used on 12.5 kHz 
    spaced nets. Open up the microphone and check 
    electret microphone front is clean and element is 
    properly seated in its holder. 
     
    5. Does your conversion defeat the Philips 
    PDP and CDP programming tools? 
    Yes. Having converted the radio it will no longer 
    recognize the PDP or CDP. 
     
    6. Is your firmware and displayware suitable 
    for 4-metre (E0-band) FM1000s? 
    No, it is not. The E0 band version of the 
    FM1100/1200 radio is extremely rare in the 
    Netherlands. An update may be developed in the 
    future. 
     
    7. Is your firmware and displayware suitable 
    for FM1000s with a basic or standard 
    console? No, it is not. The text and graphics used by the 
    conversion exceeds the capacity of the standard 
    head, which only allows a number of fixed 
    symbols to be used and does not have a numeric 
    keypad. The basic console does not even have a 
    display so its use is out of the question. We 
    suggest upgrading the radio by getting your 
    hands on a numeric keypad head. 
     
    8. Where can I obtain the complete 
    documentation of these wonderful radios? 
    A documentation package is available, consisting 
    of (1) FM1100 Service manual, (2) Numeric 
    Keypad Manual and (3) FM1200/1300 Service 
    Supplement. The lot weights approx 1 kg. Price 
    Euro 20 incl. P&P. Please contact Jan, PE1CSI 
    on email [email protected]. 
     
    9. On my radio, the display test does not work 
    to start with. Im getting solid black blocks 
    only. 
    This problem may be caused by a faulty or 
    incorrectly fitted display EPROM, or LK4 (A15 
    jumper) in the display console being set to the 
    wrong position. If the display EPROM is an 
    27C128 or 27C256, the centre pad of LK4 should 
    be connected to +5V (left-hand position). If a 
    27C512 is used, LK4 should be connected to A15 
    (default position, right-hand). 
     
    10. I have just acquired an FM1000 radio at a 
    local rally. Can I use it with your conversion? 
    This is the most annoying question we get. There 
    is no such thing as an FM1000. The designation 
    FM1000 refers to a family of more than 50 
    different transceivers rather than an individual 
    type. First do your homework by analysing the 
    type code printed on the label at the rear of the 
    radio. Use Appendix B for reference. 
     
    11. I have available a boxful of FM1000 parts 
    and other Philips PMR bits, what should I do 
    with it? 
    Contact Jan Buiting, PE1CSI, proprietor of the 
    Philips Mobile Radio Collection, on email 
    [email protected]. Jan will give you a Freepost 
    address so you can turn your surplus into a 
    donation to the Collection and pay no postage. 
     
    12. Is your firmware and displayware suitable 
    for VHF or UHF FM1100s? 
    Not completely. Watch for postings in the 
    [FM1000] Newsgroup, or [uk.amateur.radio].
