Esd Caution; Battery Replacement - Anritsu Spectrum Master MS2711E User Manual

General Information

1-13 ESD Caution

The Spectrum Master, like other high performance instruments, is susceptible to electrostatic
discharge (ESD) damage. Coaxial cables and antennas often build up a static charge, which
(if allowed to discharge by connecting directly to the Spectrum Master without discharging
the static charge) may damage the Spectrum Master input circuitry. Spectrum Master
operators must be aware of the potential for ESD damage and take all necessary precautions.
Operators should exercise practices outlined within industry standards such as JEDEC-625
(EIA-625), MIL-HDBK-263, and MIL-STD-1686, which pertain to ESD and ESDS devices,
equipment, and practices. Because these apply to the Spectrum Master, it is recommended
that any static charges that may be present be dissipated before connecting coaxial cables or
antennas to the Spectrum Master. This may be as simple as temporarily attaching a short or
load device to the cable or antenna prior to attaching to the Spectrum Master. It is important
to remember that the operator may also carry a static charge that can cause damage.
Following the practices outlined in the above standards will ensure a safe environment for
both personnel and equipment.

1-14 Battery Replacement

The battery can be replaced without the use of tools. The battery compartment is located
on the lower left side of the instrument (when you are facing the measurement display).
To remove the battery:
1. Slide the catch toward the bottom of the instrument.
2. Pull the top of the door away from the unit.
3. Lift out the battery door.
4. Remove the battery pack from the instrument by grabbing the battery lanyard and
pulling out.
Replacement is the opposite of removal. The battery key side (slot below the contacts) should
be facing the front on the unit and slide in first.
When inserting the battery the battery label should face the back of the instrument
Note and the guide slot on the battery should be below the contacts. If the battery door
does not latch closed, the battery may be inserted incorrectly.
