1-4 Battery Replacement General Information

ESD Caution
The LMR Master, like other high performance instruments, is susceptible to ESD damage.
Coaxial cables and antennas can easily build up a static charge, which (if allowed to discharge
by connecting directly to the LMR Master without first discharging the static charge) may
damage the instrument input circuitry. Operators must 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 LMR Master, Anritsu
Company recommends that any static charges that may be present be dissipated before
connecting coaxial cables or antennas to the LMR Master. This may be as simple as
temporarily attaching a short or load device to the cable or antenna prior to attaching to the
LMR Master. Remember that the operator may also carry a static charge that can cause
damage. Following the practices outlined in these standards helps to ensure that a safe
environment exists for both personnel and equipment.
1-4 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). Refer to
Figure 1-1. To remove the battery:
1. Slide the catch toward the bottom of the instrument.
2. Tilt 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) must be
facing the front on the unit and slides in first. Press the battery inward firmly to seat the
contacts, then reinstall the door.
Note
When inserting the battery, the battery label must face the back of the instrument,
and the guide slot on the battery must be below the contacts. If the battery door
does not latch closed, the battery may be inserted incorrectly.
