Operation
Detecting Live Circuits (VOLTAGE method)
The RT30 can be directly clamped on installed building wiring and will detect the voltage applied to the wiring.
1. Slide the transmitter power switch to the VOLTAGE position. The POWER
LED will switch on.
2. Slide the Receiver power switch to the ON position. The POWER LED and the SIGNAL OK LED will switch ON.
3. Place the Romex TM /nm cable (AC wire) directly into the wire clamp slot or, alternatively, connect the external voltage detector probe into the external probe socket and then clamp the probe to any cable, extension cord or appliance cord.
4. If the cable is “live” (voltage present), the VOLTAGE/LIGHT amber LED on the transmitter will switch on and the
DETECT LED on the receiver will switch on.
5. If desired, switch the receiver power switch to the audio OFF position to disable the audible tone.
6. When the voltage is removed (by opening the splice or the circuit breaker, for example), the Detect LEDs will switch
OFF and the detect beeper will switch OFF.
Note: Use of the External Probe overrides the setting of the Power/Mode Switch. The Lighting method cannot be used while the External Probe is attached.
Detecting Live Circuits (LIGHTING method)
In situations where access to circuit wiring is limited, the RT30 can also detect room lighting changes (ON to OFF).
1. Slide the transmitter power switch to the LIGHT position. The
POWER LED will switch on.
2. Slide the Receiver power switch to the ON position. The POWER
LED will switch on.
3. Cover the Light Sensor on the transmitter and press the Light
Setpoint button.
4. Expose the Light Sensor to the light source. The
VOLTAGE/LIGHT LED on the transmitter and the DETECT LED on the receiver will switch on
5. When the lights are turned off the VOLTAGE/LIGHT LED on the transmitter and the DETECT
LED on the receiver will switch off, indicating the light has been switched off and power has been removed.
Note: Before use, always test the light on/off operation for proper sensitivity and detection.

Maintenance
Battery Replacement
When the Power LED begins to dim, or the transmitter and receiver stop communicating, the batteries may need to be replaced. Each unit uses two (2) ‘AAA’ batteries (MN2400 or equivalent).
The battery doors can be removed using a Philips screwdriver to loosen the attaching screw.
You, as the end user, are legally bound (EU Battery ordinance) to return all used batteries, disposal in the household garbage is prohibited! You can hand over your used batteries / accumulators at collection points in your community or wherever batteries
/ accumulators are sold!
Disposal: Follow the valid legal stipulations in respect of the disposal of the device at the end of its lifecycle
FCC Part 15 (RT30)
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.
