4 751G Color Mobile Computer User’s Manual
External Headset Jack
The external headset jack connects a mobile phone style headset to the
751G for use in noisy environments. The jack is a 2.5 mm, three-
conductor jack, with autosensing of the headset jack insertion which
disables the internal speaker and microphone. The external headset jack is
located on the bottom of the 751G next to the Hirose docking connector.
Battery
If your computer shuts down because of low battery conditions, your
computer does not operate. This is done to ensure that data is protected.
Although the battery does protect the data against loss for several hours,
you should connect your computer to a power source when you first detect
a low battery condition.
In short, put the 751G into a suspend (sleep) mode before you remove
the main battery.
The 751G comes with a 14.4 Watt-hour, 7.2V, replaceable Lithium-Ion
(LiIon) battery. To view the status of this battery from the 751G, tap Start
> Settings > Control Panel. Double-tap the Power icon, then tap the
Battery tab. Tap OK to exit this applet.
Note: Your computer has an internal backup super capacitor, a temporary
power storage device, that protects data for up to ten minutes. It also shuts
down the 751G if the main battery suddenly goes away (removed from the
computer). Depending on the processes running, it may not have adequate
power for a graceful shutdown. If so, the 751G performs a cold-boot the
next time power is applied.
