The supplied rechargeable NiMH batteries are the preferred types for the maximum duration. Please take special attention in your choice of batteries!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. This connector is to be used only for factory service. 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. [. . . ] The user needs to pay special attention to the placement of the antenna, the antenna of the base station needs to have a "line of sight" to the antenna of the beltpack. All objects that are within that path will make the connection less reliable. This starts with the 19" rack itself, the maximum available distance behind the rack will be less than in front of the rack. The base stations WS 200 and WS 400 are available in versions with the antenna connectors at the front or at the rear panel. [. . . ]
