Your unit is ready to wire into your lighting system, but you must
select an appropiate resistor for R11.  Various resistor values are
shipped with the unit, and a 200K is intalled as delivered.  The 200K
is correct for a 5.2 volt bulb.  You must change the resistor if you
are using a different voltage bulb by unplugging the 200K and
replacing it as follows (unless you are using a 5.2 volt bulb):

       Voltage     R11           Bulbs
 -----------------------------------------
      5.5 V        220K        HPR36
      5.2 V        200K        HPR50, 425
      4.8          160K        K-15 Krypton
      3.75         100K        Petzl standard and halogen, HPR-41, K-3
      2.8           47K        HPR52
      2.33          33K        K-1, K-2, K-4, K-222, PR-2, 243

Your unit is otherwise ready to go.  DO NOT adjust VR1.  It has been
set already and does not need to be touched again, regardless of what
value for R11 you select or how many times you change it.

Once the resistor is changed then the unit is ready to wire up.  See
the wiring section of the instructions.  Note also that if the power
is connected backwards to the unit R10 will burn out immediately,
however nothing else will be damaged.  This 2 cent part will save the
rest of the unit from damage, but if you don't have a soldering iron
and a replacement resistor this could prove frustrating.  My
suggestion is to be careful about battery polarity so this doesn't
happen.  However, if it should happen, don't despair, I will fix it
for free if you send it back to me with a self address stamped
envelope for its return.

Also, if you have purchased the low power version there are two
resistors (R3 and R8) which are not on the board.  This is not a
mistake, as these resistor are not needed with the CMOS 555's.
