Battery Usage
The HMT140 has a built-in battery meter. This meter is
based on a count of its transmissions. To determine battery
life remaining, the meter records the amount of power used
during transmission relative to the power remaining.
Viewing Battery Life Remaining
The HMT140 Utility displays the estimated battery
expiration and the estimated battery life percentages on the
Status
page.
Note:
The shorter the transmit period, the shorter the
battery life.
CAUTION:
When replacing batteries, the meter must be
reset to recognize the new battery status.
To view battery life remaining:
On the
Status
tab, view the batter meter status in the
Est. Life
field.
To reset the battery meter after installing new batteries:
Note:
To install new batteries, see Battery Replace-
ment on page 48.
