Basics on how to use the transmitter
CTT33 transmits 33kHz (32,768Hz) signal always when it is on. The default output power is sufficient for most needs.
If BOOST mode is selected (BOOS LED on) output signal is higher but batteries are also drained faster.
When PULSE LED is on continuously, output signal is continuous. Press PULSE button once or twice to choose 4Hz or
8Hz pulsed signal correspondingly. With receiver pulsed signal is often easier to distinguish from noises. Two pulsed
signal modes enable using the two transmitter method for locating wire cuts.
Feeding cords are used to connect the transmitter to the target. Standard cords are safe when properly used but
safety precaution must be followed all the time when working with live wires. If galvanic connection and feeding is not
possible, inductive signal feeding with a clamp-on transformer may be used instead.
Warnings concerning the transmitter
When operating with mains targets, always use contact proof and right safety class cords and
adapters, and follow safety instructions.
CTT33 transmitter may be connected to max. 230V rms voltage!
If either transmitter output terminal is connected to a live target, dangerous voltage or current
may appear on wires connected to the other output, unless they are properly grounded.
Avoiding interference with telecommunication or electric network is always the responsibility of
the user.
Risk of electric shock: Always disconnect feeding cords before opening the battery lid or
enclosure.
