2.3. Using NiCd Rechargeable Batteries:
Each TED needs 6 NiCad rechargeable. You cannot charge the batteries inside the device. To load
the batteries you need a separate charger. The LED (3) shows the battery capacity during the
normal operation.
Blinking of LED (3):
The LED has in the signal strength
test a different function (see point 3.5).
The TED switches automatically off, as soon as the battery voltage is lower than 5 Volt!
Empty Battery Warning:
TED-TX: TED-TX: When the LED (3) switches to red on the TX, it sends along with the next
impulse or data string a message to the TED-RX. The TED-RX then turns on an alternat-
ing high and low sound to indicate that the TED-TX needs new batteries.
TED-RX: When the LED (3) switches to red an alternating high and low sound indicates that the
TED-RX needs new batteries. Make sure you check both units every time you hear teh
alternating sound.
Working duration of batteries:
The measurements shown bellow are made with NiCad batteries (type Panasonic 700 mAh) at
room temperature (25°C, 77 F). Please notice that the capacity of batteries drops fast at low tem-
peratures (at -20°C (-4F) only about 80 % capacity).
Color of LED (3) Battery Capacity
green 15 to 100%
border between green and orange about 15 %
orange 5 to 15 %
border between orange and red about 5 %
red less than 5 %
