Power Modes and Batteries

Power Modes

The MX9 has three power modes: On, Suspend and Off.

On Mode

The Display

When the display is On:

•the keypad, touch screen and all peripherals function normally

•the display backlight and keypad backlight are on until the Backlight timer expires

The MX9

After a new MX9 has been received, a charged main battery inserted, and the Power key tapped, the MX9 is always On until both batteries are drained completely of power.

When the main battery and Super-cap battery are drained completely, the unit is in the Off mode. The unit transitions from the Off mode to the On mode when a charged main battery is inserted or external power is applied and the Power key is pressed.

Suspend Mode

The Suspend mode is entered when the unit is inactive for a predetermined period of time or the user taps the Power key. MX9 Suspend timers are set using the Power control panel Advanced tab.

Wake-up Events - all configurable via Power Management API call:

•Any key on the keypad

•Stylus touch on the touch screen

•Handle trigger press

•Connecting to AC adapter

•Power button tap

•USB connection

•COM port control CTS

•Real time clock

•Bluetooth device reconnect / disconnect message

When the MX9 wakes up, the Display Backlight and the Power Off timers begin the countdown again. When any one of the above events occurs prior to the Power Off timer expiring, the timer starts the countdown again. The MX9 needs to be placed in Suspend mode before hotswapping the main battery.

Off Mode

The unit is in Off Mode when the main battery and the Super-cap battery are depleted. Insert a fully charged main battery and press the Power key to turn the MX9 On.

TSuspend

The Suspend mode is entered when (1) the unit is inactive for a predetermined period of time, (2) the user taps the Power key, or (3) Start > Suspend is chosen. Inactivity means that no devices are causing interrupts to reset the power state.

The Suspend timer is set using Start > Settings > Control Panel > Power Properties > Schemes tab.

By default, any of the primary events listed below will wake the unit and reset the User Idle, System Idle, and Suspend tim- ers. Wake up events are all configurable via a Power Management API call.

When the unit wakes up, the User Idle, System Idle and the Suspend timers begin the countdown again. When any one of the above events occurs prior to the Suspend timer expiring, the timer starts the countdown again.

The first wakeup key press or touch is not sent to the operating system or running application. The first key press or touch is only used to wake up the unit and reset the timers. Once the unit has transitioned from the Suspend mode to the On mode, the unit, keyboard and touch screen function normally.

The transition to the Suspend power state occurs during the following events:

•Timeout of the User Idle, System Idle and Suspend inactivity timers.

•The Power key on the target device is pressed.

•An application program calls the Suspend function.
