Q. Where can I find the Option Number on my product?

A. If available on the product, the Option Number will be listed on the ratings label. Option Numbers do not appear on all Lester Electrical products. In this situation, the easiest way to find the Option Number, is to look at the original invoice. We understand that this may not always be possible, especially considering the considerable size of the secondary market for Lester Electrical products. Luckily, most Option Numbers refer to specific DC cordsets, AC cordsets, charge profiles, branding, etc, so the owner's manual is often the same for all options. If there is any doubt, however, as to what the Option Number is for your product, please contact a Lester Electrical customer service representative at 402-477-8988 or by email at

Q. I get errors that say "A font required for font substitution is missing." and "Cannot find or create the font 'WASP39LC'. Some characters may not display or print correctly."

A. These messages are not uncommon. The font that is missing, WASP39LC, is a licensed font used to print the bar code normally found in the upper right hand corner of the first page. This bar code is used for tracking purposes in our packing and shipping process. The error message just indicates that the font is not installed on your computer. Clicking "OK" on both of these messages will not result in losing any data or text from the body of the manual. The bar code is not necessary for you to print out a copy or save a copy of the document.
