Getting Started
Introduction
The Nickel Metal Hydride (NiMH) Battery supplied with the Site Master is shipped in a
discharged state. Before using the Site Master, the internal battery must first be charged for
three hours, either in the Site Master or in the optional battery charger (Anritsu part num-
ber: 2000-1029).
Charging a New Battery
New batteries normally require three to five charge and discharge cycles before attaining
maximum performance. The NiMH battery supplied with the Site Master has already com-
pleted three charge and discharge cycles at the factory and full battery performance should
be realized after your first charge.
Charging the Battery in the Site Master
The battery can be charged while still installed in the Site Master.
Step 1. Turn the Site Master off.
Step 2. Connect the AC-DC adapter (Anritsu part number: 40-115) to the Site Master
charging port.
Step 3. Connect the AC adapter to a 120 VAC or 240 VAC power source as appropriate
for your application.
The green external power indicator on the Site Master will illuminate, indicating
the presence of external DC power and the battery will begin charging. The indi-
cator will remain lit as long as the battery is charging. Once the battery is fully
charged, the battery indicator will turn off. If the battery fails to charge, contact
your nearest Anritsu service center.
Charging the Battery in the Optional Charger
Up to two batteries can be charged simultaneously in the optional battery charger.
Step 1. Remove the NiMH battery from your Site Master and place it in the optional
charger (Anritsu part number: 2000-1029).
Step 2. Connect the lead from the AC-DC adapter to the charger.
Step 3. Connect the AC-DC adapter to a 120 VAC or 240 VAC power source as appro-
priate for your application.
Each battery holder in the optional charger has an LED charging status indicator. The LED
color changes as the battery is charged:
Red indicates the battery is charging
Green indicates the battery is fully charged
Yellow indicates the battery is in a waiting state (see below).
