A.H. Systems Model EHA-51B Active Monopole and Loop Antenna

CHARGING THE BATTERY

Position the input voltage selector to the proper voltage (either 110 – 120 Vac,

60 Hz or 220 – 240 Vac, 50 Hz). Be sure to check the available voltage and

adjust the voltage selector as needed before use. The amplifier ON-OFF

switch must be in the OFF/CHARGE position to charge the battery. Every

hour of charge will result in two hours of operation for up to 10 hours of

charging. Charging for up to 24 hours will not damage the battery. Using the

battery charger to operate the amplifier directly is not recommended.

REPLACING THE BATTERIES

Remove the four 6-32 flat head screws from the bottom of the base unit.

Disconnect the battery lead from the PC card. Re-connect the lead from the

new battery pack assembly to the PC card. Snug the four 6-32 flat head

screws.
