DEVICE DESCRIPTIONS

2Password (does not apply to paging consoles without selection keys)

3 or 4-digit passwords provide protection for paging consoles against unauthorized operation. Password protection can be established in two levels. The first level is the ‘normal’ user-level. In case this level is password-protected, the paging station cannot be operated except for launching an alarm. The second level is the setup-level. If this level is password-protected, the setup-mode is not accessible while unlimited ‘normal’ operation is possible.

Level 1 and 2 passwords are assigned and transferred to the individual paging stations during the PC- configuration procedure. As factory preset the level 1 password is set to ‘111’ and the level 2 password is ‘2222’; level 2 (setup-mode) is password-protected (factory pre-set).

To prevent a paging station from unwanted access, you have to enter setup-mode and select parameter 2 “password”. Depending on which function of the paging console you want to protect, by using the selection keys you have to enter either the 3-digit level 1 password or the 4-digit level 2 password. Protection is now activated and operation (1st level) and/or programming (2nd level) are not possible anymore. The blinking PROGRAM LED indicates this status.

The protection is canceled by re-entering the correct password while being in setup-mode.

3Pre-Gong Signal

It is possible to program a pre-gong signal that is heard before an announcement. The pre-gong signal is transmitted into the selected areas when pressing the TALK-button. You can begin with your announcement during the transmission of the pre-gong signal; you can talk “into” the pre-gong.

Using the arrow keys (<>) first select parameter 3. Now, you can ignite the pre-gong signal with the ‘￿‘ key or cancel it by using the ‘￿‘ key. The pre-gong function can also be activated or deactivated during PC- configuration.

4Buzzer

The integrated buzzer can be programmed as acoustic alert signal. During failure, malfunction, or as general alert a buzzing sound is heard. When an alarm has been launched, the buzzing can be heard for the whole period of the alarm.

First, select parameter 4 using the arrow keys (<>). Now, you can activate the buzzer by pressing the ‘￿‘ key. Pressing the ‘￿‘ key deactivates the buzzer. The buzzer function can also be activated during PC- configuration.

5Compressor

The paging stations’ microphone pre-amplifier incorporates compressor / limiter circuitry. While the limiter is constantly activated, the compressor can be switched ON or OFF. When the compressor is engaged, low- level signals are amplified to a higher degree, which results in constant talking levels although the distance between the announcer and the microphone varies. Besides, you have to keep in mind that also environmental noise is amplified. Thus, on-site testing with and without compressor will reveal which results in the better performance.

First, by using the arrow keys (<>), select parameter 5. Pressing the ‘￿‘ key activates the compressor. Pressing the ‘￿‘ key deactivates the compressor. It is also possible to activate the compressor during the PC- configuration procedure.

6Time / Date (does not apply to paging consoles without selection keys)

The connected paging stations allow setting the date and time of the PROANNOUNCE system.

First, by using the arrow keys (<>), select parameter 6. Using the selection keys 1 to 10 – with the 10-key representing the “0” – you can enter the correct time. Date and time are indicated in the following format: tt.mm.yy hh:mm. They have to be entered in that sequence

7LCD-Contrast

Paging consoles with display allow the user to individually adjust LCD-contrast and viewing angle. This allows optimum legibility from the user’s location.

First, by using the arrow keys (<>), select parameter 7. Now, you can adjust the LCD-contrast via the ‘￿‘ or ‘￿‘ keys.
