Vectron User manual 1.1 Important comments for application! Initiation Remove devices from packaging. Keep packaging material for future shipment purposes! Accu blocks are not inserted in HW 90196 at time of delivery. After unpacking of box accu blocks have to be inserted in HW 90196. A final functional test of the HW 90196 and its peripheral devices should be performed before delivery to customer. Application • • • • Safety • Do not operate in close range of strong electromagnetic fields.
User manual Vectron 1.2 Bring-in service (repair of devices) In case of a necessary repair the device should always be send in with all equipment in original packaging to Höft & Wessels. The equipment may faciliate trouble-shooting as sometimes defective peripheral devices can be the cause for malfunctions.

Vectron User manual 3.4 Power consumption Following table shows an approximate overview of power consumption of mobile terminal HW 90196 at different operating states (BIOS terminal:‘09905, firmware radio module: #09907). The measured values during operation depend on the current accumulator voltage. The measurement has been taken with an accumulator voltage at 3,8 V while discharged accus provoke higher currents.
User manual Vectron 4. Power supply of HW 90196 with accu block HW 19196 The power supply of HW 90196 is realised by an accu block which is inserted in the device. The accu block HW 19196 consists of a module of 3 NiCd-cells with a total capacity of 1000 mAh. The accu block HW 19196 has been specifically designed for use in the HW 90196. Contacting is realised by two high-current contacts which are sunk in sockets to avoid unintentional short-circuits. High-current contacts fig.
Vectron User manual 4.2 Charging condition of accu block The loading capacity of accu block should always be used to full extend. Keep HW 90196 in operation until the message „attention! Recharge batteries!!!“ is indicated in the display. After this the device can still be used for a while, however only essential inputs should be entered and the accu block be recharged afterwards. If the accumulator voltage drops below a permitted value, the device switches off automatically.
User manual Vectron 4.4 Maintenance of accu block If accu blocks are stored, they should be re-charged on a regular basis. After a period of 6-8 weeks, even a new accu block is discharged to such an extent due to self-discharge that it is no longer possible to operate a HW 90196 with it. About how to store device and accu block see also 1.1 „Important comments for application“. IMPORTANT! A stored MDE which is not used, has to be recharged once per month.
Vectron User manual 5. Operating system Preface Those functions which are explained in this chapter are installed as standard features in the operating system of the HW 90196 and are independent of the type of application program. The user will usually not have to deal with the operating system, as during normal operation only the displays of the application program are presented. These are explained in detail in the corresponding documentation of the application program.

The power consumption during printing depends much on the print image. The pulse motor will be supplied with power for 15 seconds after each printout (see 2), holding the printout tight for easy tear off.
User manual Vectron 6.2.2 Function indication LEDs A list of all LED-combinations will be shown in the following. The green LED usually indicates the accu charging condition: • on = „ok“, • flashing = „low“ oder „discharged“. The red LED indicates several error conditions: • off = „ok“, • on = „no paper“ resp. „open casing flap“, • flashing = „no radio connection“. Additionally, the green LED flashes every 2 seconds, if the printer is at sleep mode.

Vectron User manual Each basestation has assigned a fixed generic hopping pattern. Co-located basestations may use the same generic hopping pattern or different generic hopping patterns without restriction. Endpoints support the whole set of generic hopping patterns. When an endpoint establishes a connection to a basestation it detects, during the synchronization procedure, the generic hopping pattern to be used. 10.5.
User manual Vectron 10.6.2 Monitoring of the environment Both sides, basestation and endpoint regularly and independently perform RSSI scans of all accessible hopping channels and time slots. The basestation broadcasts on its dummy bearer a list of allowed hopping channels and time slots. Any endpoint maintain a list of quietest channels, i.e. preferred values (l,k) for setting up a connection. 10.6.3 Setting up a connection Connection setup is always initiated by the endpoint.
Vectron User manual 10.7 Interference avoidance strategies 10.7.1 Interference within the system The medium access procedures provide sufficient mechanisms so that there is no relevant interference within a system. Only endpoints send out a signal that are synchronized to the basestation. In a synchronized system only signals interfere that use the same bearer b(i,l,k).
User manual Vectron 10.7.3 Interference from other sources Other frequency hopping systems may cause occasional packet loss which is solved through packet retransmission. The same applies to CW interferers. In case the interference pattern of a specific interferer tends to disturb specific time slots or hopping channels, the system will avoid these channels. Since the hopping is fast and is spread over the whole band it may stand even interference from microwave ovens.
Vectron User manual 10.8 Specific requirements from FCC chapter 15 10.8.1 15.203 Antenna requirement An intentional radiator shall be designed to ensure that no antenna other than furnished by the responsible party shall be used with the device. The use of a permanently attached antenna or of an antenna that uses a unique coupling to the intentional radiator shall be considered sufficient to comply with the provisions of this Section. The antennas of the product are permanently attached. 10.8.2 15.
User manual Vectron 10.8.6 15.247 Operation within the bands ... 2400 – 2483.5 MHz ... (a) Operation under provisions of this section is limited to frequency hopping and direct sequence spread spectrum intentional radiators that comply with the following provisions: (1) Frequency hopping systems shall have hopping channel carrier frequencies separated by a minimum of 25 kHz or the 20 dB bandwidth of the hopping channel whichever is greater. The product uses a channel spacing of 1.
Vectron User manual (h) The incorporation of intelligence within a frequency hopping spread spectrum system that permits the system to recognize other users within the spectrum band so that it individually and independently choses and adapts its hopsets to avoid hopping on occupied channels is permitted.
