USER’S GUIDE

Chapter 1. Overview

Thanks for using this 2004 LCD Smartie Asset by Sure Electronics. It features an easy-to-install aluminum alloy housing which makes this product shapely and durable to be used in many applications. It’s also populated with a mirror screen which blocks your eyes from seeing the inside but ensuring perfect display effect when the item is powered. Its basic functions include displaying system information of your computer, such as Everest status, MBM status (Your CPU temperature, fan/cooler speed, etc.), BBC world news (or any other RSS feeds), WinAmp status (currently playing tracks title, length, position, etc), network status (speed, total bytes, etc), CPU speed, free disk space, memory usage, E-mail details, game status and many others. Features like ambient temperature display, conversion between ℃and ℉, feedback current LCD contrast ratio, backlight brightness level, tips function and product info are added. In addition, users may adjust the contrast ratio of LCD display and backlight brightness.

Chapter 2. Tips for Usage

1 If the contrast ratio, backlight brightness and displaying contents vary after running

LCD Smartie application, it proves that LCD display has successfully received the info from LCD Smartie.

2 The backlight brightness can be adjusted only when the backlight is turned on.

Otherwise, the backlight brightness cannot be adjusted once the backlight is turned off. LCD display will turn the backlight off upon receiving the command of “Turn backlight off” even when the communication is in progress. Therefore, the backlight brightness cannot be adjusted by the slider bar and users need to click “Backlight off” first and click “Backlight On” again. Please refer to item 4 in Quick Start for details.

3 Katakana will be displayed if the characters sent by your computer exceed the

range of common ASCII code. 4 Please refer to 5 Do not use LCD Smartie and Sure-LCD simultaneously. 6 Tips will not be displayed once the power is off. If you send newly-created tips to

MCU, previous tips will be replaced. 7 You may refer to help of application for use of Sure-LCD.
