2. Safety Summary
2.11. Do Not Remove Covers or Panels
To avoid personal injury and risk of electric shock, do not open the CT100B case unless replacing
the battery and do not operate unless the case is fully intact.
WARNING: Disconnect power, USB, Ethernet, and test cables prior to
opening the CT100B case to replace the battery. Failure to do so can render
an electric shock.
2.12. Connecting Cables to the Test Port
To avoid damage to the CT100B and the very sensitive sampling electronics associated with the
front panel BNC or SMA connector, do not connect it to any cable or device that can be driven by
active circuitry or is subject to transient voltage spikes.
WARNING and CAUTION: The instrument should never be used to test
any cable or device carrying live electrical signals, as this carries a risk of
electric shock. This could also damage the sampling electronics and will
void the Warranty.
CAUTION: Always properly ground the conductor(s) of any cable or wiring
to remove any static charge prior to connecting it, either directly or indi-
rectly through attachment to another cable, to the CT100B’s front panel
test port connector. Failure to do so can damage the instrument’s sensitive
sampling electronics and will void the Warranty.
2.13. Battery Replacement and Disposal
The CT100B contains an internal battery pack. The internal battery pack is 2700 mAh, NiMH,
12 AA cells, 14.40 volts, 38.88 Wh. There is also a 120 mAh lithium button cell of 2.8 volts and
0.336 Wh. Depending on the state or local jurisdiction, these batteries may require special disposal
and/or recycling. Contact your local authorities for safe disposal in your area, or you may return
them to MOHR for recycling.
WARNING: The battery pack must be replaced with MOHR pn: CT100-
AC-B2700. Use of any other battery pack will damage the instrument and
pose a danger of fire.
