CLEANING
Occasional cleaning may be required, depending on use. It is
recommended that you create a “Clean” button somewhere on the Home
page of the T4. This button should link to a page that does not contain
commands or macros that could be inadvertently executed while cleaning
the unit.
BATTERY AND DOCKING STATION
The T4 uses a Lithium-polymer rechargeable battery. This battery does not
exhibit any type of “Memory Effect” from being charged too often. Since
the T4 can safely be charged after each use, a docking station is included
for convenience. If left out of the docking station, the T4 will remain in
sleep mode for 1 – 2 months before shutting down. At that point the
battery must be recharged.
If the T4 battery capacity is reduced to approximately 25 percent, the low
battery LED located on the front bezel of the T4 will illuminate red.
Alternatively, if the keypad backlights are programmed to be disabled, a
low battery icon will appear in the top center of the display:
The low battery icon will change color to red if the battery capacity
becomes critically low:
At this point the T4 must be placed into the docking station to recharge the
battery.
The docking station LED illuminates red to indicate a charge in progress.
The LED will turn green when the battery in the unit is fully charged.
A fully discharged battery will take approximately 4-5 hours to completely
re-charge.
