Section 12 - Maintenance
12.1 Battery Replacement
To replace the batteries, remove the OSA from the protective boot by pulling the bottom of the boot down and
back allowing the bottom of the unit to be lifted out. The battery door is located on the back side of the unit.
Replace the batteries with only high quality AA NiMH batteries. Spare battery packs are available with a charging
unit for extended battery operation. If you install NiMH batteries that are dead or less than 1 volt each, charge these
batteries for one hour before using the OSA. For proper maintenance, batteries require a monthly recharge.
Warning
To Prevent Fire or Shock Hazard:
• Do not install battery types other than those specified by the manufacturer
• Do not use the charger without the batteries installed
• Do not expose the battery charger to rain or excessive moisture
• Do not use the AC adapter when there are signs of damage to the enclosure or cord
• Ensure you are using the correct charger for the local line voltage
• Do not use any other charger than the one provided with this instrument
• Failure to follow these caution statements may void the warranty of this equipment
Note
For maintenance, batteries require a monthly recharge.
