This WS 19 will form part of an existing or new intercom system in combination with a WS 200 or WS 400 base station. [. . . ] The WS 19 uses a high discharge current that the batteries need to sustain over the whole lifespan. Batteries that can only supply a high current for a short time will be exhausted very quickly. When the batteries reach the end of their capacity the beltpack will warn you with 4 short tones, the interval of the tones will shorten when the batteries wear out. 17 Dipswitch This dipswitch controls four functions of the WS 19, these are: A B C D Talk function only momentary Talk function disabled. Battery save mode. The dipswitches are turned on by sliding them towards the side panel of the beltpack, they are turned off when slid to the battery compartment. Do not connect anything to it and do not short circuit any of the pins. 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, eg. 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. C) turn the sidetone trimmers counter clock wise. Turn down the OWN VOICE volume trimmer at the side panel of the beltpack. (clockwise) Switch on the TALK function of the beltpack (TALK button). 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 8. 2 BELTPACK SETTINGS Select with the channel select switch at the rear of the beltpack the channel to match the WS 200 or WS 400 setting. When the beltpack is switched on then a single short tone should be heard and both led's on the front panel of the unit will flash for half a second. If you press the CALL or TALK button the led's on the front panel will be lit and the corresponding TX/RX unit of the base station will show a green ACTIVE led. 9. 0 8. 3 SIDETONE ADJUSTMENT This system is designed to offer a 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 listening beltpacks can talk at a time and have a full duplex connection. [. . . ] - due to the high bridging impedance offered by each station, the number of stations 'on line' has no influence on the level of the communications signal. 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 19 POWER CONSUMPTION current (at 9 V DC) 200 mA quiescent 280 mA signaling 450 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.
