LectriCalc(tm) is so easy to use, you don't need a lengthy user's manual.

________________________
Installation:

To run LectriCalc(tm) on your Palm-style Personal Digital  Assistant (PDA),
install LectriCalc.PRC and LPlusDat.PDB using your PDA's desktop install
program.

UPGRADING FROM ElectriCalc 1.0 or 1.1: this new program does not replace
your existing ElectriCalc software on the handheld computer. If you no
longer need ElectriCalc, just delete it from your device.

UPGRADING FROM LectriCalc/LectriCalcPlus 1.2 or above: these files replace
your old files on the device. Just install them. No need to delete your old
program files first.
--------
After "hotsyncing" the files to your PDA, you will see a new icon, 
a little calculator with "lightening" around it, on the PDA screen. 
This is the icon you tap to start LectriCalc(tm).

TO EXIT LectriCalc(tm), tap your PDA's "Applications" button, which generally
looks like a little house, located to the left of your PDA Graffiti area.

Registering your software:

To convert the trial version to fully operational software, you need a
registration code, available through PalmGear.com or Handango.com. Visit
http://www.geocities.com/arkansoft for links to the sales sites.

After obtaining your registration code, install LectriCalc.PRC and
install LPlusDat.PDB (if you haven't already).

Tap the LectriCalc icon on the handheld computer to start LectriCalc.

It will say "Trial Version" at the top of the screen.

Tap the [Register] button in the lower right area of the screen.

When the Register screen appears, tap the numbers and letters on the screen
to enter your registration code.

After entering your registration code, tap the [Submit Registration] button
in the lower left area of the screen.

  If you get an Error message "Invalid registration code"
  tap the [OK] button then check the code you entered (it
  appears above the [Submit Registration] button) and
  determine where you made a mistake in data entry.
  Then tap the [Reset] button to clear your incorrectly
  entered code and try again.

If you enter the code correctly, the [Submit Registration] button will
return "Registration successful. Thanks!".

Tap the [OK] button and your new program is registered and ready to use.

Using LectriCalc(tm):

	NOTE: Look for (i) information icons on some LectriCalc(tm) screens. 
         	Tapping them will bring up helpful information about the 
		screen you're currently viewing.

The LectriCalc(tm) main menu features several different calculators. Tap the one
you want to work with.

_______________________________________________________________________________

1. Voltage Drop Calculators: Use the dropdown menu to select for standard
   voltage or low voltage lighting applications. 

   a) Low Voltage Lighting
      This calculator is designed for use in design and installation of low
      voltage lighting applications. As you run power through a cable, voltage 
      drops off based on the length of the cable and the cable size. If cable 
      runs are long, or if cable diameter is small, voltage drop can become 
      significant enough to cause problems. For instance, if voltage drop is 
      over 1.5 volts on a 12-volt system, lights attached to the cable can 
      appear dim and yellow instead of bright and white. 
      The Voltage Drop Calculator can calculate a number, based on data you 
      enter, to give you an idea of what size cable must be used to carry power
      a given distance.

      OPTIONAL: If most of the wattage on the cable is drawn from the first half
          of the cable run, tap the radio button beside 
          "Most fixtures on 1st 1/2 of cable", to adjust calculation accordingly.
          If most of the wattage draw is in the last half of the cable, tap the 
          checkbox "Most fixtures on 2nd 1/2 of cable", to adjust the calculation
          accordingly.

      To use the calculator, enter the total wattage of fixtures attached to the 
      cable and the length (in feet) of the cable, then tap the [Calculate] button 
      to perform the calculation. Voltage drop results for different cable sizes is 
      show in the lower area of the screen. Acceptable cables sizes will be in
      a darker font.

      To exit the calculator, tap the [<] button in the upper right corner of the 
      screen.

   b) Standard Voltage
      This calculator is for more advanced applications. 

      IF YOU ARE USING the Imperial (English) measurement system, you must tap a
      radio button to indicate if you're calculating for DC, Single-phase AC, or
      3-phase AC. Enter Amps, one-way cable length from power source to the load,
      and, if desired, a Power Factor. For unity power factor, leave the setting at
      the default 1.0.
      Optionally, check the Aluminum checkbox if you're working with aluminum wire
      instead of copper.
      Tap the Calculate button to perform the calculation.
      The amount of voltage drop, percent drop, and resulting operating voltage will
      be reported for various wire sizes. Use the [<] and [>] buttons in the upper
      right corner of the screen to see more screens of data.
      If any cable in the calculation generates a voltage drop over 4%, you will 
      see a reminder of that. Voltage drop appears in bold font for cables that
      produce voltage drop that doesn't exceed 4%.

      IF YOU ARE USING the metric measurement system, use the dropdown lists to 
      indicate cable size and type, then enter the number of watts you're dealing
      with, source voltage and length of cable in meters. Tap the calculate button
      to see the results. Excessive voltage drops (those over 4%) will be marked
      on the output screen.

2. Amperage Calculator: Use the dropdown menu to select the type data the calculation
   will be based on. Then tap the [Amps] button, supply the requested information
   and tap the [Calculate] button to perform the calculation.  

   To exit the calculator, tap the [<] button in the upper right corner of the screen.
________________________________________________________________________________

3. The other two buttons let you find Wattage/Kilovolt-Amps, Kilowatts and Horsepower
   based on data you enter.

At the bottom of the screen, you can tap the Reference area to bring up a menu of
helpful data. 

You can tap the lightbulb icon to find the candle power of a light
source at a given distance from the light source. 

Tap the stack of money to find a
calculator to help you estimate the cost to run lights or equipment per day/week/
month/year.

  NOTE:
  Instead of entering kilowatt hour cost directly, you can tap the little calculator
  button to the right of the cost field, then enter data from your utility bill and 
  tap the "Insert" button to have the computer calculate the KWH cost and plug it into
  the energy cost calculator for you.

_______________________________________________________________________________

4. Beaming
   You can beam LectriCalc to another handheld computer by using the "Beam" choices
   on the dropdown "top menu" available at the top of most LectriCalc screens.
   Be sure to send both the LectriCalc program and the reference database.

5. Measurement Preference
   Select Ft/M on the program's dropdown "top menu" to switch back and forth between
   measurements in feet and meters, as needed.
