Prior to the wiring of the terminal blocks for power input and contact signal
output circuits, make sure that the power cord is unplugged. You are
warned against working on live circuits as they involve fatal electric shock
hazards.

Ground the Bell Timer Model QBT-30 by connecting a grounding
conductor to its grounding terminal. This is important for the prevention of
electric shock hazards in case of troubles such as earth leakage fault.
The grounding work must be Class D or higher in rating.

After wiring the terminal blocks for power supply and contact signal output
circuits, be sure to replace the terminal board cover for the protection of
operators against electric shock.

SEIKO bell timer Model QBT-30 serves as an analog clock. In addition, QBT-30 is capable of being
programmed to play melodies automatically at preset times and/or deliver contact signal output to
external circuits. A weekly programming system is used to specify the sequence of these operations on
a day-of-the-week basis.
If SEIKO TimeLink(R) transmitter-receiver or LF radio receiver available as optional feature is used, it is
possible to receive the standard radio wave automatically at regular intervals to keep accurate time for
QBT-30 at all times.
