Manual

Open a book and pick up where you left off

In PocketBook Library, long-press an EPUB or FB2 book and choose Open with → CoolReader. If that choice is missing, follow the Library setup instructions.

Opening CoolReader from Applications reopens your last available book. On a fresh installation, it opens the welcome book. To switch to another book you have already read, open CoolReader’s Main menu → Recent books. You can also return to Library to choose a different book.

Turn pages and open the menus

Use the reader’s page-turn buttons, or tap the middle-left and middle-right parts of the screen. Horizontal swipes turn pages when Page Turn Swipes is enabled.

To change these actions, open Settings → Controls → Tap action or Long tap action. Choose a screen region, then assign an action. You can also change the region sizes and turn swipes or pinch zoom on or off. Existing personal settings may differ from the defaults above.

Find a chapter or go to a page

Open the quick menu and choose Contents to jump to a chapter. The available headings come from the book; a book without a chapter list may have little to show here.

In the touch menu, drag the progress bar to move through the book, or tap its page text to enter a page number. If your reader shows the grid-style quick menu, choose Go to page. Page numbers can change when you change the font, spacing or screen orientation.

Save and revisit bookmarks

Open Bookmarks from the quick menu and select a saved entry to return to it. Hold an entry to open its actions: Set bookmark, Go to bookmark or Delete bookmark.

In the touch toolbar, holding the bookmark icon adds a bookmark to the current page. Holding it again on an already bookmarked page removes that bookmark. A short tap opens the bookmark list.

Search inside a book

Choose Search in the quick menu, type a word or phrase and confirm. Use the search navigation controls to move between matches. Close search to return to normal reading.

Search looks for text inside the current book, not book titles in Library. If nothing is found, try a shorter word or check the spelling.

Look up a word

Choose Dictionary in the quick menu, then select a word on the page. The dictionary view uses dictionaries installed on your PocketBook. Choose the dictionary you need in that view; if no suitable dictionary is installed, add one through the reader’s usual dictionary setup.

Keep a passage

Open Cite from CoolReader’s Main menu. Use its selection controls to extend or shorten the highlighted passage, then confirm to save it. Open Citations in the Main menu to revisit saved passages. Holding a citation opens its jump and delete actions.

Make the text comfortable

Open Settings → Font & text to choose a font, change its size or weight, and adjust line spacing. The font sample lets you preview changes before applying them.

• Font size: use +/− to make the text larger or smaller.
• Font weight: 0 is Normal, 0.5 is Medium and 1 is Bold. Values between them give finer control; higher values make the text heavier. The range is 0–1.75 in steps of 0.25.
• Line spacing: increase it for more space between lines, or reduce it to fit more text on a page.
• Document embedded fonts: keep this on to use fonts included in the book. Turn it off if you want the book to use your chosen reader font.

Choose Done to apply your changes. Back returns to the previous settings group. Cancel on the main settings screen discards changes you have not applied.

Check the label at the top of Settings: This book, Reader defaults or Format defaults. It tells you which settings you are editing. A book with its own saved settings can look different from your defaults.

Adjust the page layout

Open Settings → Page layout.

• Page margins: set the space around the text.
• Hyphenation: choose the book’s language when available, or turn hyphenation off if you prefer whole words.
• Footnotes at page bottom: show supported notes beneath the main text. Results depend on how the book marks up its notes.

More detailed controls are under Advanced. If a book’s own formatting is preventing your preferred layout, check Advanced → Style settings → Document embedded styles. Turning it off can also change headings and other book formatting.

Screen, rotation and reading progress

Settings → Screen & sleep contains orientation, screen refresh, standby and status-line options. Choose Orientation to switch between portrait and landscape.

Under Status line settings, choose whether to show page numbers, reading percentage, time, battery and chapter progress. Optional frontlight indicators show whether the light is on, its brightness and its warmth level. Use the reader’s lighting controls to change brightness or warmth.

If faint traces of previous pages remain on the screen, try a more frequent full refresh in Display update mode. Full refreshes clear the screen but cause a visible flash.

Save your place and close the book

CoolReader saves your reading position as you use it and when you leave the app or put the reader to sleep. Reopening the same book should return you to that position.

Use the app’s normal exit before connecting USB or replacing application files. Keep a backup of your settings and history when upgrading. Sudden power loss can still lose the most recent page turn.

Check for updates

Connect the reader to Wi-Fi, then open Settings → About & updates → Check for updates. Version shows your installed version. You can turn automatic checks on or off in the same group.

Follow the update instructions before installing an update. If CoolReader cannot start, use the USB installation instead.

Add books over Wi-Fi

Use Easy Connect’s FTP server to copy books from your computer without a USB cable. Refresh the PocketBook Library after the transfer, then open the book with CoolReader.

When something does not look right

• The chosen font is not used: turn off Document embedded fonts. If the book still overrides your settings, check its embedded styles under Advanced.
• A change did not stick: choose Done, reopen Settings and check the scope label. Another book may use its own settings or different format defaults.
• The page number changed: changing the text layout can change pagination. Use a chapter or bookmark to find the passage again.
• A tap does something unexpected: check Tap action and Long tap action under Controls.
• CoolReader fails to open or repeatedly loses your place: note the book format, reader model, firmware and steps, then report the problem. Keep system/cr3-pb.normal.log and system/cr3-pb.crash.log if present.
