4.11
Use caution when working with telephone lines. They can
support dangerous voltages. 50VDC is often present, and
100VAC may be present during ringing. Additionally, tele-
phone lines may support dangerous levels of common mode
voltages. In some circumstances, user injury may result.
4.12
Use caution when working with any long unconnected wire
or cable. Under some conditions, unconnected wires may
“float up” to dangerous potentials, and touching them may
result in user injury.
4.13
Use care when using the HOUND 3 to probe any wire or cable.
An unexpected dangerous voltage may be present, which
may result in injury to the user.
4.14
Potentials applied to the HOUND 3’s probe may appear,
greatly reduced, at the earphone jack. This could pose a shock
hazard to the user, if for example, the probe is brought in
contact with a high voltage potential.
4.15
The HOUND 3’s metal probe can accidentally short out a cir-
cuit that is being tested. Use care when testing live circuitry,
or an accidental short may result in equipment damage or
user injury.
