User Manual WS 19 / Issue 1 © 2002 ASL Intercom, Utrecht, Holland. 7 8. 0 SETTING UP A CONNECTION 8. 1 BASE STATION SETTINGS A) The base station must be set up properly according to the user manual. Give each TX/RX unit of the base station its own channel by rotating the `Channel select' switch. Try to avoid concurrent channels to be physically next to each other, e. g. in a setting of two WS 400's try to set them in this order: 2, 4, 6, 8, 1, 3, 5, 7 If you use a WS 200 with only two beltpacks use channels 1 and 6. B) Connect the base station to the partyline intercom or 4 wire system and make sure the interface mode switch at the back is set accordingly. 8. 2 BELTPACK SETTINGS Select with the `Channel select' switch at the rear of the beltpack the channel according to the WS 200 or WS 400 setting. When the beltpack is switched on, a single short tone should be heard and both LEDs on the front panel of the unit will flash for half a second. If you press the CALL or TALK button the LEDs on the front panel will be lit and the corresponding TX/RX unit of the base station will show a green ACTIVE led. 8. 3 SIDETONE ADJUSTMENT Turn down the OWN VOICE volume trimmer at the side panel of the beltpack (counter-clockwise). Talk in the microphone and listen to your own voice, you might hear a small delay in the signal. Now turn down the volume of your own voice by adjusting the SIDE TONE trimmer at the base station of the TX/RX unit to which the beltpack is connected. Adjust the trimmer so that the level of your own voice is as low as possible. Now turn up the volume of your own voice by adjusting the OWN VOICE trimmer to a level that you like. 8. 4 FULL DUPLEX AND HALF DUPLEX USE Although the system is designed to be used in full duplex use, there is a possibility to use the system in half duplex mode too. Half duplex allows more than 1 beltpack on the same frequency and therefore, on one TX/RX unit of a base station. Every beltpack will be able to listen to the base station, but only one of the beltpacks can talk at a time and have a full duplex connection. As long as one of the beltpacks has a full duplex connection, the others are not able to CALL or TALK. In this mode it is useful not to adjust the sidetone trimmer on the base station, turn it fully counter clockwise. [. . . ] It develops a DC potential over the line impedance, which will be sensed by each station and interpreted as a Call signal. 13. 0 TECHNICAL SPECIFICATIONS WS 29 POWER CONSUMPTION current (at 9 V DC) 200 mA quiescent 240 mA signaling 260 mA at max. impedance gain presence filter frequency response V electret mic 200 ohms 40 dB - 70 dB +6 dB at 5 kHz 200 Hz - 12 kHz (-3 dB) +9 V DC HEADPHONES DRIVER AMP max.
