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.
T
Suspend
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.
