1-14 ESD Cautions
The MS202xA and MS203xA, like other high performance instruments, are susceptible to
ESD damage. Very often, coaxial cables and antennas build up a static charge, which, if
allowed to discharge by connecting directly to the MS202xA or MS203xA without first
discharging the static charge, may damage the instrument input circuitry. Operators should
be aware of the potential for ESD damage and must 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 standards apply to the MS202xA and MS203xA, it is
recommended that any static charges that may be present be dissipated before connecting
coaxial cables or antennas to the MS202xA or MS203xA. This may be as simple as
temporarily attaching a short or load device to the cable or antenna prior to attaching to the
MS202xA or MS203xA. 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
help ensure a safe environment for both personnel and equipment.
1-15 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. Slide the battery door down (towards the bottom of the
instrument) to remove the door. Remove the battery pack from the instrument by pulling
straight out on the battery lanyard. Replacement is the opposite of removal.
