Bird AT-800 Antenna Tester

Fully charged batteries will provide a minimum of 2

hours continuous operation with the backlight on.

Charging time is typically 8 hours. The batteries are

being charged when the Antenna Tester is connected

to AC, with the AC mains adapter, or DC, with the

automobile cigarette lighter adapter cable. The unit

does not have to be on to charge the batteries.

Note:

For optimum battery life, charge the

batteries only after the low battery indication is
displayed.

Batteries and Long Term Storage

Do not store the instrument for long periods of time

without recharging the batteries. When the instru-

ment is stored for long periods of time without use, the

batteries will loose their charge and also loose the abil-

ity to reach full charge when put into service. To

restore the battery charge, perform a full charge for 8

hours. If the batteries are not fully charged after eight

hours, completely discharge the batteries then per-

form a full charge again. If necessary, repeat this dis-

charge and charge cycle up to three times. If the

batteries do not remain charged after three discharge-

charge cycles, replace the batteries.

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

If subjected to an ESD spike directly to the metal portion

of the case the unit may go into an interrogative state. A

power cycle of the unit may be required to return to
