4-1 General Information
The following information relates to the care and handling of the Anritsu 633-75 battery pack and Lithium-Ion
batteries.
• The battery supplied with the Spectrum Master may need charging before use. Before using the
Spectrum Master, the internal battery may be charged either in the unit using the AC-DC Adapter

(2000-1374).

• Recharge the battery only in the Spectrum Master or in an Anritsu approved charger.
• When the Spectrum Master or the charger is not in use, disconnect it from the power source.
• Do not charge batteries for longer than 24 hours; overcharging may shorten battery life.
• If left unused a fully charged battery will discharge itself over time.
• Temperature extremes affect the ability of the battery to charge: allow the battery to cool down or warm
up as necessary before use or charging.
• Discharge the battery from time to time to improve battery performance and battery life.
• The battery can be charged and discharged hundreds of times, but it will eventually wear out.
• The battery may need to be replaced when the operating time between charging becomes noticeably
shorter than normal.
