Touch Operations

Touch Screen Operation

The touch screen replaces a mouse in normal Windows operation. Wherever you touch the screen with your finger or stylus, the computer interprets it as a mouse click. Due to the nature of the touch screen, it is sometimes hard to drag objects across the screen and it is also hard to move the pointer around the screen without selecting the object below the cursor. This should be taken into account when applications are being developed for touch screen devices.

The touch screen unit comes standard with Windows XP Pro, Pen Office Calligrapher and My-T-Pen on screen keyboard software and therefore may not offer some of the Tablet PC functionality of a pen unit running XP Tablet PC Edition such as screen rotation. It is also very difficult to capture a signature on touch screen units.

Caring for the Touch Screen

With minimal maintenance, the touch screen will last many years. When operating the touch screen, you should not use an abrasive or metallic pointer. The touch screen is easily scratched if an abrasive stylus is used. We recommend using your finger or a plastic tipped stylus. Be careful not to let sand or grit sit on the screen. Cleaning of the touch screen can be done with a regular plastic cleaner such as Plexus.

Battery use and care

The Lithium Ion batteries used in your Hammerhead computer offer the best technology available today. These 'Smart Batteries' provide Hammerhead users with the greatest power density and the most accurate gas-gauge possible. To achieve the best possible performance from your batteries, we recommend using and maintaining the batteries in accordance with the instructions provided below.

Getting started with your new batteries

Your unit comes with a Lithium Ion battery that is shipped (uninstalled) in the box with the unit. The unit may also have a non-working battery shell in the second battery slot that shows you how the battery is to be installed. Due to current regulations regarding shipment of Lithium Ion batteries, your battery(s) will arrive in a partially charged condition, typically with a maximum charge of 30% to 50%. You need to install your battery before turning on the unit. We also recommend that you fully charge your batteries before using them. If you do not plan to deploy your computer immediately, please be aware that the batteries self-discharge at a slow rate, typically less than 10% per month at normal temperatures.

How to install new batteries

The Hammerhead RT has the capability to run on one or two batteries in the field. The unit does not require both batteries to run. The two-battery design allows users to hot swap batteries without turning the computer off.

To install or replace a new battery, turn the round knob on the back of the unit. The knob holds the batteries in place and is designed so the batteries cannot be taken out at the same time. Simply turn the knob until the quarter piece exposes the corner of the battery that is to be replaced. A lip on the battery aids for easy removal. Install the new battery by placing it into the compartment and turning the knob to cover the edges of both batteries.

When to recharge batteries

The green LEDs on the upper right front of the unit indicate the power status of the battery. At full charge, all five LED indicators will light a solid green. Each LED represents approximately 20% of the total charge.
