Sleep Mode
After a period of inactivity (no button pushes, no data wheel turns, no display updates), TranzPort
automatically goes into low-power sleep mode — all of its lights (including the display backlight)
are turned off, and the display is cleared.
Turning the data wheel does not interrupt sleep mode. When TranzPort is in sleep mode, simply
press any button to resume operation. This button press will not be recognized as a command by
the computer. The display briefly shows the firmware version and battery level, and then
TranzPort automatically reconnects with the computer (if it’s still within range) and updates the
display and lights.
The sleep mode delay time is set to 15 minutes by default. To adjust the length of inactivity before
TranzPort goes into sleep mode, press and hold SHIFT, and then BACKLIGHT, and turn the data
wheel. You can set the sleep mode delay time between 1 minute and 60 minutes.
Battery Life
When you press the BATTERY button, the display shows the current battery level for a few
seconds, and then reverts back to the previous display. The battery level is shown as a bar graph
with up to 10 asterisks enclosed in a pair of brackets. If no asterisks appear in the display, you
should replace the batteries with four new batteries.
TranzPort can be powered with a wide variety of AA-size batteries. It comes with four alkaline
batteries, however you can use four non-rechargeable “zinc-carbon” batteries, which are less
expensive, but only have about a third of the energy storage. You can also use four rechargeable
AA-size NiMH or NiCAD batteries. (Note that when using fully charged rechargeable batteries,
the BATTERY display may not show all ten asterisks since they charge to a slightly lower voltage
than fresh alkaline batteries.)
TranzPort does not have an on/off switch since it uses very little power when it goes into sleep
mode. A new set of alkaline batteries would last for several years if the TranzPort was left in
sleep mode.
With backlighting off, TranzPort provides about 100 hours of active use on one set of alkaline
batteries. With backlighting on, that time is somewhat reduced. So, if you use TranzPort for 2
hours a day, 5 days a week, without backlighting, a set of four batteries should last about 10
weeks.
