CAUTION: Electronic equipment is sensitive to Electrostatic
Discharge (ESD). Observe all ESD precautions and
safeguards when handling the timecode generator.
CAUTION: It is necessary to use an external diode when driving
inductive loads (e.g., relays). The diode should be
situated as close to the load as possible, and connected
across the load so that it is reverse-biased when the
output is low. The user is responsible for choosing the
proper diode. It should be capable of suppressing the
induced energy from the collapsing magnetic field.
