2.3.3
Low Battery Warning
The TPT is designed to operate for approximately 8 hours on a fresh set of batteries. After
approximately 7½ hours, the operator will get two battery indications; an audible “BATTERY
LOW” SynVoice warning through the headset, and a blinking red LED, BATTERY LOW, on the
front of the unit. After 20 minutes of additional use, the SynVoice will announce “BATTERY
EMPTY” through the headset. Shortly thereafter the TPT will automatically turn off.
2.3.4
Charging the TPT
When the low battery warning sounds, the operator may either install a fresh set of batteries or
recharge them. Alkaline batteries must be replaced for continued use. NiMH batteries can be
recharged while still in the TPT unit. Simply place the unit into an open holder on the TSS and
power the TSS up. As the batteries are charging, the LED will blink with an alternate red/green
color. The LED will illuminate with a steady green light when the batteries are fully charged.
Note
NiMH batteries must be recharged within 8
hours of “Battery Empty” or automatic
shutdown. Failure to do so may render batteries
unable to be charged in the Support Station.
See Figures 2.3.4-1 and 2.3.4-2 for unit dimensions and additional battery installation information.
