Chapter 3 Installation
The following paragraphs will explain how to connect
the Bird Antenna Tester for various operations. See
“Component Description” on page 2 if needed.
Power Supply
The AT-800 can use an external power source. Using
the ac adapter or the 12V cigarette lighter adapter
cable will also charge the battery. Using the ac
adapter, charge time is about 8 hours. Using the ciga-
rette lighter adapter cable, charge time will depend on
the car battery charge. Battery life is 2 hours continu-
ous operation, minimum, with the backlight on. “Lo
Batt” is displayed when the batteries require charging.
Note: This unit is shipped with the batter-
ies not charged. Charge batteries for at least 8
hours before use.
Note: For optimum battery life, only
charge the batteries after the low battery indi-
cator is displayed.
CAUTION
Follow guidelines for battery charging.
Avoid constant charging of batteries for long periods
of time. Overcharging can result in reduced battery
efficiency, service life, and possible permanent
damage.
CAUTION
Only use the AC adapter provided with the AT.
Do not use the adapter with the batteries removed.
