Enable Proximity Attention Sensor:

Select this option

to enable or disable the proximity attention sensor. The

sensor is used to wake up the HMT140 and to cause the

HMT140 to send a data packet to the host.

Display On Time:

Select the length of time the display

stays on when the HMT140 is battery-powered (choose a

minimum length of time to save battery power).

HMP110 Polltime:

If your device uses an HMP110

Probe, select how frequently the HMT140 polls the

HMPT110 probe (leave at the default setting, two min-

utes).

Low Battery Alert:

Specify at what percentage of battery

life remaining you want the Low Battery indicator to dis-

play and notify the host software. For more information

see, Viewing Battery Life Remaining on page 37.

Stop Xmit at Battery Remaining:

Specify at what per-

centage of battery life remaining you want the HMT140

to stop transmitting data to the host (to save battery

power). Once this threshold is reached, the HMT140

functions normally except it will not transmit data using

the Wifi radio.

Use the Display Contrast

interactive control to set the

HMT140 display contrast. When the Up, Down or Set

buttons are clicked, the HMT140 Utility will attempt to

set the contrast.

Note:

The contrast value can only be set when you click

Set. The value is not set with the Update or

Retrieve buttons.

Click Update. The HMT140 Utility will send these

settings to the HMT140 and then reboot. After the

settings are successfully configured, a dialog displays

Configured!

If there was an error sending the settings,

the HMT140 Utility will display the error in a popup

dialog window. The center panel in the bottom status bar

will display the update status.

Select the Status tab to check that the settings appear as

configured. Click Get if they do not appear

automatically.

Disconnect the HMT140 Configuration Cable from the

HMT140 and wait eight seconds.
