SGA/SGV Generators and MXT Transmitter: Technical Specifications
Controls:
All operation is by push button control as follows:
- On/Off
- Power Level:
SGA 2 available power levels via High and Low Power buttons
SGV 4 available power levels via Increase and Decrease buttons
MXT cycles through 4 available power levels
- Frequency: (MXT only) cycles through 3 available output
frequencies using one push button
- Pulse/Continuous Output: toggles between pulse
or continuous output using one push button.
- Audio/Mute: toggles between high or low level audio output
using one push button
Indications:
Audio
- Audio Feedback on button push.
- Audio pitch drops with increasing load current in connected mode
- Audio pitch changes with power level in induced mode.
- Audio output pulses to indicate Pulsed Mode.
- Low battery indicated by interrupted Audio and output signal.
Visual (SGV and MXT only):
Multi-segment Liquid Crystal Display.

Note:
Performance figures stated can be affected by site parameters such as
ground conditions, temperature, and strong electromagnetic fields.
All C.Scope Generators/Transmitters are in compliance with the
essential requirements and other relevant provisions of Council Directive
1999/5/EC. Compliance has been demonstrated by testing representative
samples to the harmonised standards EN300-330 and EN301-489.
The essential radio test suites have been carried out and the equipment
is in conformity with all applicable directives.
All C.Scope Generators/Transmitters comply with the RoHS directive,
2002/95/EC.
