Chapter 3 Installation

The following paragraphs will explain how to connect

the Bird Antenna Tester for various operations. Refer to

the component description diagram on

page 2 if needed.

Power Supply

The AT-500 can use an external power source. Using

the ac adapter or the 12V cigarette lighter adapter will

also charge the battery. Using the ac adapter, charge

time is about 8 hours. Using the cigarette lighter

adapter, charge time will depend on the car battery

charge. Battery life is 2 hours continuous operation,

minimum, with the backlight on. “Lo Batt” is dis

played 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.
