Calibration Mode; Dip-Switch Configuration - AUDIOropa T-Sign Bedienungsanleitung

Calibration mode

1. Turn off »T-sign« by unplugging the DC connector or disconnecting the power supply
from the mains electricity.
Wait a few seconds until it has shut down.
2. Turn the light intensity knob to minimum.
3. Turn on »T-sign« by plugging the DC connector in or by reconnecting the power supply.
4. After the initial one- or two green flashes (depending on program selection), turn the light
intensity knob of the »T-sign« to maximum. This must be done within two seconds after the
green flash(es) are seen.
5. »T-sign« now indicates that it is in calibration mode by two short green double-flashes.
6. When in calibration mode, the »T-sign« shows the magnetic field strength in real time
where it is mounted. The calibration mode is used to adjust the sensitivity, so that the
»T-sign« changes color from green to red when the magnetic field strength at its location
reaches 400 mA/m at 1 kHz.
If you don't have access to a measuring device, adjust the sensitivity while sending a strong
signal to the hearing loop (as received at a normal listening position within the audience
area) so that the »T-sign« turns red when the transmission is loud.
Depending on the setting, the »T-sign« will be more or less prone to change to red when a
strong signal is received.
7. Finally, disconnect the power supply, wait approximately five seconds and then recon-
nect the power supply again.

DIP-switch configuration

• DIP-sw 1: Automatic control of light intensity related to environmental light (off/on)
• DIP-sw 2: Reduced sensitivity for weak signals under 3 dB (off/on). This can be a helpful
feature when high sensitivity is needed in combination with some interference in the
vicinity.
• DIP-sw 3: Change indication of strong signal from a steady red light to flashing red
light (off/on)
• DIP-sw 4: Program selection 1 & 2
